Site Drainage

Trusted Foundation Repair for Residential & Heavy Commercial

Over time the soils around you home may settle, heave or erode. This change in contour can result in negative drainage toward your home which may lead to water intrusion, water damage, and even foundation failure. Drainage does not just include the soils around your home but it also pertains to patios, porches, decks, sidewalks and any other type of surface that can trap water or carry it away from the home. Repairs can vary from simply regrading the existing soils up to a complete redesign of the site to include changes in landscape materials and in ground drains.

Straight Line Construction offers a variety of drainage solutions. Call or click today for a free on-site evaluation. Below is a list for some of our site drainage solutions.

  • Regrading of existing soils
  • Import, backfill and grading of new soils
  • Concrete leveling (Mud Jacking and Poly Foam Lifting)
  • Concrete removal and replacement

Perimeter Drains

Trusted Foundation Repair for Residential & Heavy Commercial

Water seems to always find a way in! Basic exterior drainage plays a large part in protecting your home from water intrusion but many times drainage is not enough. A perimeter drain (Interior or Exterior) may be the correct solution to your water problems. If water is making its way to the base of your foundation, we can install the drain on the inside or outside of the wall and footing to capture water, divert it to a collection pit and pump it up and away from the foundation.

If you are experiencing problems with water intrusion, leaking basement walls, or wet basements, contact Straight Line Construction today for a free on-site evaluation.

Below is are just a few of the services we offer to help correct water problems in and around your home.

  • Exterior Perimeter Drain (set outside the footing)
  • Interior Perimeter Drain (Set inside the footing)
  • Waterproofing compound applied to the exterior walls
  • Protection board laid over the waterproofing compound to reduce the chances of rocks and roots wearing off the compound
  • Waterproofing membrane that prevents water from getting to the foundation walls and if it does, creating a channel for the water to make its way directly to the exterior perimeter drain at the bottom of the exterior footing

Soldier Pile and Lagging

Trusted Foundation Repair for Residential & Heavy Commercial

Soldier Pile and lagging is an earth retention technique that retains soil, using vertical steel piles with horizontal lagging. Steel Piles (steel I-Beam or W section) are installed at regular intervals along the excavation perimeter. Lagging can vary (wood, steel or precast concrete panels) and are inserted behind the piles front flanges as the excavation proceeds. The lagging resists the load of the retained soil and transfers it to the piles. The walls can receive additional lateral support from anchors or bracing.

Soil Nail and Shotcrete

Trusted Foundation Repair for Residential & Heavy Commercial

When permanent shoring is required to maintain soils and slope, Soil Nail and Shotcrete is an excellent choice with many advantages to counter sliding, bearing failures and stabilize sloughing soils. Soils Nails are drilled into the face creating a tension element. A plate and wire mesh form are tied into the nails along the face of the area. Shotcrete is then blown over the form creating a continuous solid structure to support the soils and resist soil pressure.

Call us today or fill out our contact form for more information. Our consultants are available to schedule a comprehensive consultation and evaluation of your project.

Advantages:

  • Creates a reinforced earth mass
  • Can be installed in 4’ to 5’ lifts to allow for steep or vertical excavation
  • Provides External and Global Stability
  • Shotcrete Flash may be used to prevent sloughing or soils collapse
  • No backfill and compaction required
  • Several installation methods from tight confined spaces to large vertical slopes
  • Used in conjunction with vertically installed piers and piles to stabilize and or extend existing foundations

Auger Cast Piles

Trusted Foundation Repair for Residential & Heavy Commercial

Auger Cast piles are installed by rotating a continuously flighted hollow shaft auger (CFA) of approximately 12” to 36” in diameter to soil depths of up to 100’. High strength cement grout is pumped under pressure through the shaft as the auger is slowly withdrawn. Reinforcing steel placement occurs immediately after the auger is withdrawn and extends into the concrete cap. Auger Cast Piles are best suited for Deep Foundation elements, Cantilevered Shoring and Tie-back Shoring.

Call us today or fill out our contact form for more information. Our consultants are available to schedule a comprehensive consultation and evaluation of your project.

Advantages:

  • Use of temporary casing or slurry to support the drill hole is unnecessary
  • Drilling is one continuous process and faster than drilled shaft as the drill bit doesn’t have to be lowered into the hole multiple times to complete excavation

Disadvantages:

  • Torque requirement to install CFA is much higher when compared to drilled shaft; therefore, field conditions may dictate shorter installation depths
  • Limited to soils and very weak rock profiles

Push Piers

Trusted Foundation Repair for Residential & Heavy Commercial

Push Piers sometimes referred to as resistance piles (not to be confused with a Driven Pile). They are used to underpin the foundation of an existing structure. Each pile is pushed into the soil with hydraulic cylinders by using the weight of the structure as a reaction force. The structure must have sufficient weight to allow enough force to be applied to the pile to reach load-supporting strata.

Call us today or fill out our contact form for more information. Our consultants are available to schedule a comprehensive consultation and evaluation of your project.

Benefits to using Push Piers:

  • Ability to install piers in areas with limited access
  • Hydraulics are run off a power pack that can access remote or difficult to reach areas
  • Each Pier is driven individually to the required specifications
  • Powerful hydraulic ram’s can quickly install pipe shafts into the soil
  • Can be used for stabilization and attempt to lift the structure

Stem Wall Repair

Trusted Foundation Repair for Residential & Heavy Commercial

The Stem Wall is the structure around your home that helps join the base of your building with all of the vertical walls built on the base. Your Stem Wall can be compromised if moisture begins to seep through the concrete and come in contact with the internal rebar reinforcement. As the steel rebar begins to rust, the surface area expands, and the pressure can blow out the concrete and reduce the strength of the foundation wall. Failure to address and treat the rebar (not just surface patching the concrete) may result severe damage to the foundation wall and loss of support for the upper structure.

The most common signs of the rusting rebar inside the foundation wall are cracking, spalling and flaking of the exposed concrete. In some cases, the rust can even stain the outer concrete surface.

Straight Line Construction can help. We take special care to address all the issues affecting your Stem Wall in order to provide a permanent solution. We address the specific issues affecting your home and complete the repair by patching all removed concrete areas with a non-shrink cement product that contains a rust inhibitor.

Call us today or fill out the form here for a free in-home evaluation.

Pier and Beam

Trusted Foundation Repair for Residential & Heavy Commercial

As older homes settle, shift and breath throughout their life, the individual foundation supports can move at slightly different rates. Extreme moisture variations in the soils can also cause the supports to heave or settle. Shifting soils can result in minor problems or result in a complete failure of the entire support mechanism. These changes can cause drywall cracking, sinking or heaving floors, cracked floor tiles cracked fireplace hearths and more.

Straight Line Construction has a variety of ways to repair out of date or failing supports. Some circumstances are easily corrected by installing simple posts and other problems may require a new support beam and base.

Call Straight Line Construction today for a free on-site evaluation or fill out the form on this site. Our team will expertly evaluate your home and offer affordable solutions. Below are just a few of the common repair services we offer for Pier and Beam failure.

  • Steel Adjustable Columns
    • Replace old wood, concrete, block, stone, brick or undersized supports

  • New Concrete Base and Adjustable Column
    • Remove undersized or non-existent base and set new adjustable columns

  • Helical Pier or Micro-Pile, Concrete Cap and Adjustable Column
    • For maximum performance, replace a failing or undersized base with a helical pier followed by a new cap and adjustable post.
    • Can also be used to replace heaving supports from future movement

  • Beam Replacement
    • We can strengthen or replace your existing support beams
    • Additional beams and bases can be added to reduce squeaking, bouncing and sagging floor joists

  • Joist Strengthening or Sister
    • Add additional support to reduce squeaking, bouncing and sagging floor joists

New Home Construction Foundations

Trusted Foundation Repair for Residential & Heavy Commercial

Foundations for new homesPre-construction helical piles can be installed during the construction process. Pre-construction piles can be used in residential and commercial applications for those who desire long term peace of mind for their structure. Investing in a deep foundation system for your home will help prevent settlement and heaving issues, preserving the value of your home for generations to come. Pre-construction piers can lessen the impacts of substandard soils often found in our region of the country. Foundation piers are easy to install, affordable, can be installed in two days or less in a new construction environment, and can be completed in any type of weather conditions.

Rely on Straight Line Construction Co. and Ram Jack to develop the most stable and cost-effective solution for your new construction foundation.

Underpinning

Trusted Foundation Repair for Residential & Heavy Commercial

When your home or portions of your home rest on soils that are subject to settling, migration or swell, the only fully permanent and warranted solution is structural underpinning. Both helical piers and micro piles are options to transfer the support of your home through the active zone of problematic soils into a more stable layer of soil.

In instances of heaving due to expansive soils beneath your home, we will place helical pier or micropile supports, undermine the entire foundation, and place a void form to create a “breathing space” between the soil’s active zone and your foundation. Once the foundation has been supported and void forms placed, our crew will lift or lower parts of the foundation using the Ram Jack foundation bracket system. The lift is often performed simultaneously with mud jacking in order to preserve floors, fireplaces, etc, and to fill any voids resulting from the lift itself. This process will return your home to as near its original state as possible. Once complete, any removed concrete will be re-poured, and we will return landscaping to its original state.

See more detailed information on helical piers and micro piles.

Concrete Slab Leveling

Trusted Foundation Repair for Residential & Heavy Commercial

Sloping floorsMud jacking, commonly referred to as concrete leveling or slab-jacking, is used to deal with the effects of settlement in concrete slabs used for driveways, porches, and sidewalks. If your concrete is sinking, the slab may have been placed on under-compacted dirt or there may be a factor such as sub-surface erosion or shrinking soils at work.

Mud jacking involves drilling a hole through the concrete and injecting a specially designed grout mixture under the slab. This mixture consolidates the soil, fills any potential voids, and raises the slab. Despite being a common repair in the upper Midwest for many years, mud jacking should only be attempted by professionals. In order for mud jacking to work properly, the technician performing the work must be experienced and have the proper equipment.



Benefits of Mud Jacking



  • It’s a green repair since it reduces the amount of concrete sent to landfills.
  • It can be done in nearly any weather conditions.
  • There is close to zero damage to landscaping.
  • Nothing needs to be moved since the pump can lift the slab and other loads on top of it.



Example of Combined Compaction Grouting and Mud Jacking



If a front porch has sagged over time due to loose backfill behind the basement walls, Straight Line Construction can mitigate the settlement issue by performing this process:



  1. Drill holes through the slab and drive grout pipes through the holes into the loose soil. Pressure pump grout to displace and compact the surrounding soil until it is stabilized.
  2. Lift the sagging slab by pumping low mobility grout just below the surface until the slab returns to as close to its original elevation as possible.
  3. Fill any remaining void spaces with a higher mobility grout to prevent future cracking or settlement. Patch holes and clean work area, leaving little evidence of the work performed.

Common Signs of Distress

Trusted Foundation Repair for Residential & Heavy Commercial

Problems caused by expansive soils usually can be traced back to one thing: water. Excessive water in the soil causes it to swell, whereas too little water saturation causes soil to shrink. When all the soil under a foundation swells or shrinks in a uniform manner, problems are not likely to occur. If only portions of the soil shift, the movement differences can cause cracking and other damage.

Increased Moisture

Expansive soils are more likely to swell than to shrink, and this swelling can come from a variety of sources. Plumbing leaks, improperly drained surface water, and a high water table all can cause moisture gain in the soil.

Decreased Moisture

When a foundation is laid, the soil may be near its optimum moisture level. Due to drought or other circumstances, though, the soil can lose enough moisture to begin settling. This moisture loss occurs most heavily around the perimeter of the building.

Poor Pre-Construction Compaction of the Building Pad

Shallow foundations are dependent on the top layers of soil to provide bearing capacity and maintain stability. If this soil is not properly compacted before the foundation is laid, the foundation will shift as the soil settles.

Another source of concern arises when a foundation is located on different types of soil. This can cause portions of a house to settle differently than others. If half of a house is situated on clay and the other half is on rock, seasonal shifting will vary throughout the house. This variance can cause damage to not only the foundation but to the rest of the structure itself.

Interior signs could mean foundation problems:

  • Misalignment of windows and doors
  • Cracked sheetrock
  • Sticking windows and doors
  • Sloped floors
  • Cracked floors and tile

Exterior signs could mean foundation problems:

  • Cracked bricks
  • Gaps around windows and doors
  • Visible cracks in the foundation
  • Separation of any fascia board

Signs in the garage that could mean foundation problems:

  • Separation from door
  • Wall rotation

Signs in the basement that could mean foundation problems:

  • Leaning of the walls
  • Cracking in the walls
  • Water intrusion

Soil Conditions

Soils that have the potential to expand or contract are found throughout the United States. These soils create problems with the performance of buildings situated on them. Within a certain range of depth, expansive soils experience seasonal fluctuations in their moisture content. These fluctuations can cause shrinkage or heaving in the soil.

When there is an increase in water levels, the soil will swell and move upward. Conversely, when there is a moisture decrease, the soil shrinks and begins to pull away from the foundation. These issues are of greater significance when the homeowner has a shallow foundation such as a slab on grade.

Perfect soil conditions are not usually the reason houses are built in a certain area. Developers choose land for many reasons, including price and availability, proximity to schools, and proximity to commerce. The driving force behind developing a certain area is, of course, consumer interest in the area. If a profit can be made from selling homes in an area, that area is desirable to developers.

If you want to know if your house sits on expansive soil, the best way to learn is to check with a geotechnical engineer. A geotechnical engineer will make soil borings, take samples from your site, and provide a written report on his findings. Another way to find out about your soil is to check if your housing development has a prepared Soils Report, although this is not required in all regions of the country.

Foundation Basics

Trusted Foundation Repair for Residential & Heavy Commercial

Due to its direct contact with the ground, a building’s foundation joins the structure of the building to the soil and rock beneath it. Referred to as a ‘second foundation,’ the makeup of this soil directly impacts how well the structure performs over time.

Slab on Grade

When speed and monetary efficiency are of utmost importance, a slab-on-grade foundation is a great option. It is a shallow foundation that is made up of reinforced concrete. These foundations will shift up and down as the ground moves and do not allow for a basement.

Like any other shallow foundation, slab-on-grade foundations will be impacted by seasonal movement. This includes temperature changes, rainfall, freeze/thaw cycles, and drought conditions.

Pier and Beam

A pier and beam foundation is made up of a series of concrete piers that support wooden beams and floor joists. When soil movement occurs, groups of these piers will move separately from each other. This independent motion causes irregularities in the floor levels. Pier and beam foundations usually allow for a crawl space but not a full basement.

Basements

Usually constructed in northern climates where freeze and thaw are permanently dueling, basements allow the footing of a home to reach below the frost line. As a result, the basement floor usually sits below where a majority of climate-related shifts occur. Despite that construction, basements are not immune to heaving floors and moving walls.

Deep Foundations

A deep foundation is exactly what you’d expect it to be – a foundation that goes deep enough to avoid seasonal changes.

There are many types of foundations other than the ones discussed here.

Tie Backs

Trusted Foundation Repair for Residential & Heavy Commercial

Tie Backs

On steeply sloping sites, pressure on retaining walls can cause major damage to built structures or slope failure. Straightline Construction can install micropiles, strand anchors, and helical piers to resist this downhill movement and reduce loads on retaining walls. By transferring loads from the wall or soil surface to the anchor, which extends beyond the “active zone” of the soil into the stable “passive zone” where it develops its resisting strength, walls and slopes are stabilized to prevent damage to structures.

Where retaining walls or foundations have been overburdened to the point of failure, we offer many repair options dependent upon the nature of failure, the structure’s size, the soil type, and the overall goals of the repair plan. Working with geotechnical and structural engineers, Straight Line Construction develops the most practical and best-fit plan to repair your home.

Simple stabilization to prevent further movement is often the most cost-effective solution. For cases that require it, we provide more intensive methods which include some demolition and excavation to achieve significant recovery of the house or building.

Overall, our soil nail and tie back products and services include:

  • New construction of retention anchors for stabilizing slopes or retaining walls
  • Temporary soil nail and shotcrete excavation shoring
  • Reticulated micropile excavation shoring
  • Post-construction repair and recovery anchors

Pre-Construction Piers

Trusted Foundation Repair for Residential & Heavy Commercial

Pre-Construction Piers

It is important to protect new construction and prevent future downward settlement before it even begins. Piers installed during the pre-construction phase of a new home, commercial building, or residential addition lessen any impacts of substandard soil. They are cost-effective, easy to install, can be installed in two days or less, and can be completed in any type of weather conditions.

Rely on Straight Line Construction Co. and our network of geotechnical engineers to assess your site and soil conditions before construction starts. We can save you money by preventing future building settlement issues.

Polyurethane Injection

Trusted Foundation Repair for Residential & Heavy Commercial

Polyurethane Injection

Sometimes an alternative method to mud jacking is necessary to raise a foundation, backfill, or fill a void under a building. Perhaps an ultra clean method is required, there is heavy foot traffic that cannot be re-routed, or the material being drilled is decorative with a need for minimal disruption. Polyurethane foam injection is an effective alternative to mud jacking.

Straight Line’s precision lift foam is designed as a simple, clean placement of expandable foam injected in very small drilled openings to lift a foundation to its original location. The foam is non-hazardous, hydro-sensitive, produces little to no mess to clean up, does not require large installation equipment, has no special disposal requirements, and is a perfect solution for large slabs or locations where there is a need to maintain cosmetic integrity.

Pile Load Testing

Trusted Foundation Repair for Residential & Heavy Commercial

Pile Load Testing

As part of our Quality Control program, we perform pile load testing on a majority of jobs, especially when installing micropiles. These tests most often include axial tension tests, but we also are capable of testing helical piles in compression applications. We perform most testing on sacrificial test piles for design verification. Some clients and engineers require proof testing of a percentage of piles on certain jobs, which we can accommodate.

Straight Line Construction provides three primary types of testing:

Verification Testing

  • Pre-production test
  • Very short bond length
  • Pile is failed
  • Ultimate bond stress value is back calculated and used in micropile design

Performance Testing

  • Pre-production and production testing
  • Test designed bond length up to 2.5 times design load
  • Calculate apparent free length to determine if designed bond length is sufficient or if pile meets acceptance criteria

Proof Testing

  • Production testing on 10% or more of production piles to ensure installation quality
  • Test up to 1.67 times the design load
  • Verify the pile meets acceptance criteria

Micropiles

Trusted Foundation Repair for Residential & Heavy Commercial

Micropiles

When conventional methods will not work, such as in low headroom areas or places with restricted access, micro piles can serve as successful substitutes. Typically 2-6 inches in diameter, micro piles are small piles that can be used in nearly any soil type.

Since each project has different soil and load-bearing needs, we work very closely with engineers to ensure we use the most suitable design based on load requirements and soil conditions. As a result, we match the best micro pile solution from our toolbox to each project’s specifications.

Micro piles are used in both new construction and refurbishing of existing foundations and in either soil or bedrock. This versatility means minimal disturbance to the surrounding soil and structures.

Advantages of Micro Piles:

  • Appropriate in both tension and compression
  • Usable in nearly all ground conditions
  • Minimal vibration
  • Minimal installation space
  • Installable in awkward spaces
  • Achievable high grout pressure
  • Better anchoring and less settling
  • High-end corrosion protection and minimal grout cover
  • Less likelihood of shearing than a rod of the same cross section
  • Economical

Helical Piles

Trusted Foundation Repair for Residential & Heavy Commercial

Helical Piles

Helical piers are used in new construction when challenging soil conditions prevent a building’s foundation from being built in a traditional manner. They also are used to stabilize a house’s foundation that has settled or failed. Helical piers transfer the load of the house from the unpredictable surface soil into deeper, sturdier earth. They are used in tension applications, such as tower guide wires and tie-back retaining walls, and in compression applications, like settlement repair, lighting poles, and tower foundations.

Helical piers work similarly to a screw bored into wood. When they are rotated into the soil, the helix plates welded onto the tubular or square-shaped shaft help stabilize the structure above ground.

Advantages of Helical Piers:

  • Green installation
  • Ready to use immediately
  • Appropriate for sensitive areas
  • Zero ground disturbance
  • Installed quickly in one visit
  • Removed and reused with ease
  • No debris to remove from site
  • No cement curing time
  • Measurable results

Resistance piers, also known as push piers, are very strong cylindrical steel tubes used in conjunction with steel brackets to lift a sagging or settling foundation. Push piers usually are installed vertically but can be installed at an angle if necessary to stabilize a foundation. Resistance piers support light loads, some heavy loads, and are used in underpinnings.

Advantages of Resistance Piers:

  • Installable in all weather conditions
  • Vibration-free with limited side effects to nearby structures
  • Ready to use immediately
  • No debris to remove from site
  • Portable equipment usable in tight quarters

Straight Line Construction Co. is a certified dealer of Ram Jack’s patented helical piers for the residential industry.

Compaction Grouting

Trusted Foundation Repair for Residential & Heavy Commercial

Compaction Grouting

If your building site has loose, grainy soil or there are known sinkholes or voids under an existing building, we address those situations with a compaction grouting technique. Compaction grouting is especially effective when used on problem soil because it displaces loose soil and adds density to support the building above it. It can create a lift of any building that has settled because of problem soils.

In the compaction grouting process, we pump a viscous grout under high pressure into the ground. This causes the surrounding soil to compact. As the grout dries and expands, it pushes aside any loose soil which forms a grout column whose size varies based on the soil’s characteristics.

Grouting takes place in measured stages beginning at the bottom of a drilled shaft and moving upward through the soft and weak soil. On shallow applications, this process is reversed allowing a “cap” to form. This reverse method causes the upper portion of the treated area to become denser first, which helps contain the grout at the lower levels.

The pressure-treated soil has an increased uniformity throughout its entirety, especially when applied in a grid style. This uniformity increases soil stabilization and provides a solid support for buildings.

Compaction grouting’s greatest effect is seen in the weakest soil under a building.

When to Use Compaction Grouting:

  • Remediating soil during pre-construction
  • Lifting structures
  • Raising existing structures (roads, bridges, towers, etc.)
  • Filling subsurface voids and rock fissures
  • Filling sinkholes

Compaction grouting is sometimes used in conjunction with mud jacking.

Carbon Fiber Repair

Trusted Foundation Repair for Residential & Heavy Commercial

Carbon Fiber Repair

Bowing or cracking basement and retaining walls, un-reinforced historical structures, and overloaded columns all can be reinforced and repaired using a system of carbon fiber/Kevlar® straps manufactured by Fortress Stabilization. Fortress has developed a concrete reinforcement system using carbon fiber technology and Kevlar straps, which wrap structures and increase lateral and blowout strength.

Repairing Basement and Retaining Walls

In some structures, insufficient reinforcement or overburden from water saturation causes walls to bow or crack inwards and eventually fail if not repaired. Traditionally, a repair contractor would excavate fill from behind the wall, temporarily shore the house or other structure above, and level and reinforce the wall with tie backs and steel channel bolted to the inside. Since this method is costly and invasive, Straight Line Construction Co. prefers to use carbon fiber strapping when possible.

If caught early when structural movement is minimal, we can place straps in vertical strips along the wall to stabilize the wall and prevent future movement. We can fill and seal cracks using epoxy injection and in some cases combine it with steel staples to stabilize the wall.

Fortress Stabilization products are the best in the industry, which is why we stand behind this permanent system of fixing basement walls and retaining walls.
