Polyurethane Injections

Polyurethane injections are an effective solution for numerous issues related to foundation repair, including cracks, leaks, and settling. This simple and non-intrusive method involves injecting a liquid polymer into the affected area, which then expands and hardens to seal and stabilize the foundation. Polyurethane injections are a quick and cost-effective alternative to other foundation repair solutions, such as excavation or rebuilding. If you suspect issues with your foundation, contact AGCS to see if polyurethane or Epoxy injections are right for your home or building.


Kevlar-reinforced strapping is a popular choice for foundation wall reinforcement due to its exceptional strength and durability. When attached to the exterior of a foundation wall, the strapping acts as a support against soil pressure and can also help prevent cracks and bulges. Kevlar is a highly resistant material that is able to withstand harsh weather conditions and is resistant to chemical and biological degradation which makes it superior to other reinforcing materials. This type of reinforcement is becoming more common in residential and commercial foundation repair due to its effectiveness and long-lasting results. Contact AGCS to see if Kevlar reinforced strapping is right for your foundation repair needs.


Depending on the cost analysis, and in serious cases, repairing the foundation from the exterior may be required. Repairing and waterproofing a foundation from the exterior involves a series of essential steps to ensure the structural integrity and protection against water damage. The process typically begins by excavating the soil surrounding the foundation to expose the exterior walls. Once exposed, any visible cracks, gaps, or deteriorated areas in the foundation are repaired using specialized materials such as hydraulic cement or epoxy injections. After the repairs, a waterproofing membrane is applied to the exterior walls, creating a barrier against water infiltration. This membrane acts as a shield, preventing water from penetrating the foundation. Additionally, a weeping tile system is installed at the base of the foundation to help redirect water away from the structure. The weeping tile consists of perforated pipes placed in a bed of gravel that collect and redirect water towards a designated drainage area, preventing water from accumulating around the foundation. The combination of proper foundation repairs, waterproofing membrane, and weeping tile system ensures a robust defense against water-related issues and helps safeguard the integrity of the building.

How Do You Know There Is A Foundation Issue​?

Signs Of Foundation Issues

Vertical Cracks​ - Foundation Crack Repair


Vertical cracks in a foundation wall can also be a cause for concern, although they may not always indicate severe structural issues like horizontal cracks. Here are some reasons why vertical cracks are considered problematic:

  1. Settlement or Foundation Movement: Vertical cracks can be a sign of settlement or movement in the foundation. This movement can occur due to various factors, such as soil settlement, inadequate soil compaction during construction, or changes in the moisture content of the soil. If left unaddressed, the vertical cracks can widen over time and potentially compromise the stability of the structure.

  2. Structural Stress: Vertical cracks can also be caused by excessive stress on the foundation. Factors such as poor construction practices, uneven load distribution, or lateral pressure from the soil can lead to vertical cracks. These cracks can weaken the integrity of the foundation, affecting the overall stability of the building.

  3. Water Intrusion: Similar to horizontal cracks, vertical cracks can serve as pathways for water infiltration. If water enters through the cracks, it can lead to moisture-related issues, including mold growth, deterioration of foundation materials, and potential structural damage. Water intrusion can exacerbate the cracks and contribute to further deterioration of the foundation.

Repair methods for vertical cracks in foundation walls include:

  1. Epoxy or Polyurethane Injection: This technique is also applicable to vertical cracks. Epoxy or polyurethane resins are injected into the cracks, filling the voids and creating a seal. This helps prevent water penetration and stabilizes the crack. However, it’s essential to identify and address the underlying cause of the crack to ensure a long-lasting repair.

  2. Crack Stitching: Crack stitching involves installing metal or carbon fiber stitching bars across the crack. These bars are embedded in the foundation using epoxy or other specialized adhesives, reinforcing the cracked area and preventing further movement. Crack stitching provides added strength to the foundation and helps distribute stress along the crack line.

  3. Wall Anchors or Tiebacks: In cases where vertical cracks are due to excessive external pressure, such as expansive soil or lateral soil movement, wall anchors or tiebacks can be used. These systems consist of steel rods or cables that are anchored into stable ground outside the foundation. They exert pressure against the foundation, counteracting the external forces and preventing further movement.

  4. Underpinning: For more severe cases of vertical cracks caused by significant settlement or foundation movement, underpinning methods may be necessary. This involves strengthening the foundation by extending its depth or providing additional support beneath the existing foundation. Common underpinning techniques include helical piers, push piers, or micropiles, which transfer the load to more stable soil layers.

Again, it’s crucial to consult with a professional structural engineer or foundation repair specialist to assess the severity of vertical cracks, identify the underlying cause, and determine the most suitable repair method for your specific situation.

Horizontal Cracks​


Horizontal cracks in a foundation wall are generally considered problematic because they can indicate serious structural issues and potentially compromise the integrity of the entire structure. Here are a few reasons why horizontal cracks are a cause for concern:

Structural Integrity: Horizontal cracks in a foundation wall typically indicate that the wall is under excessive pressure or stress. This can be due to factors such as expansive soil, hydrostatic pressure from groundwater, poor construction practices, or foundation settling. Over time, these cracks can widen and compromise the overall stability of the building.

Water Intrusion: Horizontal cracks can serve as pathways for water to infiltrate the foundation. When water seeps into the foundation, it can lead to moisture-related problems such as mold growth, wood rot, and further deterioration of the foundation materials. This can weaken the foundation and impact the stability of the entire structure.

Differential Settlement: Horizontal cracks can also indicate differential settlement, which means that the foundation is settling unevenly. This can occur when different sections of the foundation settle at different rates due to variations in soil composition or inadequate soil preparation during construction. Differential settlement can cause the foundation to become uneven, leading to structural problems and potential damage to the building.

To repair horizontal cracks in foundation walls, several methods are commonly used:

Epoxy or Polyurethane Injection: This method involves injecting epoxy or polyurethane resins into the cracks. The resins fill the voids, bond with the surrounding concrete, and create a watertight seal. This technique helps prevent further water intrusion and can stabilize the crack, but it may not address the underlying cause of the crack.

Carbon Fiber Reinforcement: Carbon fiber straps or fabric can be applied to the surface of the foundation wall to reinforce and stabilize it. These materials are bonded to the wall using epoxy or other specialized adhesives, creating a stronger structural support system that helps distribute the forces exerted on the wall and prevent further cracking.

Steel Reinforcement: In more severe cases, steel reinforcement may be necessary. This involves installing steel beams or plates to strengthen the foundation wall and prevent further movement or cracking. Steel reinforcement is typically used when the structural integrity of the wall is significantly compromised.

Excavation and Waterproofing: If the horizontal cracks are caused by hydrostatic pressure or water-related issues, excavation may be required to expose the foundation wall. Waterproofing techniques, such as installing drainage systems, applying waterproof membranes, or using waterproof coatings, can be implemented to prevent water infiltration and alleviate pressure on the foundation.

It’s important to note that the appropriate method for repairing horizontal cracks depends on the specific circumstances and severity of the issue. Consulting with a professional structural engineer or a foundation repair specialist is recommended to assess the situation, determine the underlying cause, and determine the most suitable repair method.

Water in your basement

Water in your basement is a common issue that can be caused by a number of factors, including poor drainage, plumbing leaks, or heavy rain or snowmelt. However, if you notice water in your basement on a regular basis, it could be an indication of foundation issues. Foundation problems can cause cracks in the walls or floor of your basement, allowing water to seep in. Over time, this can lead to mold growth, a damp or musty smell, and even structural damage to your home. If you notice water in your basement, it’s important to have a professional inspect your foundation to determine the cause of the issue and recommend any necessary repairs. Ignoring water in your basement can lead to more serious and costly problems down the line, so it’s important to address the issue as soon as possible.

I spoke to Zachary about getting some cracks filled in on a 10 foot tall foundation wall, and he was incredibly responsive and got out there immediately to talk through options. This was in the middle of winter and he talked me through the importance of heating and hoarding and how that will affect the quality of work, and walked us through how their process works and how it will be waterproofed. Price was incredibly competitive and pricing was all discussed in advance with no surprises. I wouldn’t hesitate to give him a call for any future needs or to recommend him to family and friends. I am also pretty sure they left the work site cleaner than when they came. Cheers!

Most Common FAQs

The most common methods for fixing a foundation include:

Underpinning is a process that involves strengthening and stabilizing the foundation by extending its depth or providing additional support. Common underpinning methods include:

  • Helical Piers: These are steel piers with helical blades that are screwed into the ground to reach stable soil layers. They provide support and lift the foundation, addressing settlement issues.

  • Push Piers: Similar to helical piers, push piers are steel piers that are driven into the ground using hydraulic force. They stabilize the foundation by transferring the load to more competent soil or bedrock.

  • Micropiles: Micropiles are small-diameter piles drilled into the ground and reinforced with steel. They are used in situations where soil conditions are challenging or when additional load-bearing capacity is required.

This method is primarily used for concrete slab foundations. It involves injecting a stabilizing material, such as a grout mixture, beneath the sunken or uneven areas of the foundation to raise and level it. Slab jacking can help correct settlement issues and restore the foundation to its original position.

Cracks in the foundation can be repaired using various techniques, such as:

  • Epoxy or Polyurethane Injection: This method involves injecting epoxy or polyurethane resins into the cracks to fill voids, stabilize the foundation, and prevent water infiltration.

  • Crack Stitching: Metal or carbon fiber stitching bars are installed across the cracks using epoxy or adhesives, reinforcing the cracked area and preventing further movement.

Waterproofing the foundation helps prevent water intrusion and damage. Common waterproofing methods include:

  • Exterior Waterproofing: This involves excavating around the foundation and applying a waterproof membrane or coating to the exterior surface. Additionally, drainage systems, such as French drains or exterior footing drains, may be installed to redirect water away from the foundation.

  • Interior Waterproofing: Interior waterproofing methods include applying waterproof coatings or sealants on the interior surface of the foundation walls, installing a sump pump system to manage water, and implementing interior drainage systems to collect and redirect water.

Encapsulation is a process that involves sealing and conditioning the crawl space or basement area to prevent moisture and humidity issues. It typically includes installing vapor barriers, insulation, dehumidifiers, and proper ventilation systems.

Soil stabilization techniques can be used to address foundation issues caused by expansive or unstable soils. Common soil stabilization methods include compaction grouting, chemical stabilization, and soil replacement.

It’s important to note that the specific method or combination of methods used to fix a foundation depends on the underlying issues, the type of foundation, soil conditions, and the recommendations of a professional engineer or foundation specialist. A thorough assessment of the foundation’s condition is necessary to determine the appropriate repair approach.

Foundation repair is the process of repairingand strengthening a damaged or faulty foundation. This can include fixing cracks, leveling the foundation, and reinforcing thestructure.

Foundation problems can be caused by several factors, such as soil movement, poor construction, water damage, and natural disasters. Some of the most common causes are soil settlement, poor drainage, and tree roots. 

Edmonton experiences frequent foundation repairs due to the intense “freeze-thaw” cycles during spring and fall seasons. Water seeps into hairline cracks, and as it freezes and expands, the cracks widen. If left untreated, these cracks can eventually allow water penetration, leading to further damage.”

Some signs that your foundation may need repair include cracks in the walls or floors, doors and windows that don’t close properly, sloping or uneven floors, and water damage in the basement or crawl space.

Foundation repairs can be completed from the interior or exterior. Depending on the specific case, one may be more cost effective than the other. We always take each repair on a case-by-case basis to ensure we provide the correct solution for your property.


Yes, foundation problems can be fixed 

through a variety of techniques. The best solution for your foundation depends on the specific issues and the extent of the damage. 

The cost of foundation repair varies depending on several factors, including the location, the extent of the damage, and the type of repairs needed. Foundation repairs can cost as low as $1000 ranging to tens of thousands of dollars or more depending on the specific issue, size of the property, and other factors. We always try to come up with an appropriate solution that solves our clients problems while sticking within their budget


Foundation repairs can be challenging to undertake during the winter months due to several factors. The extreme cold temperatures make it difficult for construction materials, such as concrete, to properly set and cure. Additionally, the frozen ground can complicate excavation and make it more challenging to access the foundation. Frost heaving, where the soil expands and contracts due to freezing and thawing cycles, can also affect the stability of the foundation. However, certain types of foundation repairs, such as minor crack sealing or drainage improvements, can be done in winter conditions. It is important to note that foundation issues often become more apparent during wet months when water-related problems arise, highlighting the need for timely repairs. Consulting with a professional contractor is crucial to assess the feasibility and effectiveness of foundation repairs during winter and to ensure the best course of action to safeguard the integrity of your home.”

The time it takes to complete foundation repair depends on the extent of the damage and the type of repairs needed.
