Repairing Foundation Wall Cracks

Whether the problem is expansive soils or unstable soils underneath your foundation, there are effective solutions that can permanently repair your foundation or structure.

Foundation Pier Systems are an excellent way to stabilize and potentially lift a foundation that is resting on soils that cannot support the weight of the home. Foundation piers are a permanent solution for homes that are settling, and they can be installed year-round.

Push Piers stabilize foundations by transferring the weight of the home deep below the foundation, reaching to bedrock or competent strata.

Helical Piers are an excellent way to stabilize foundations when there is sufficient knowledge of local soil conditions. They are advanced into the soils underneath the foundation via a helical blade.

Wall Anchor Systems are ideal for stabilizing and potentially straightening foundation walls that are buckling due to pressure from expansive soils.

Wall Anchors use the soils beyond the foundation walls to exert counterpressure on failing foundation walls. This holds the walls in place in the short term, and it allows your contractor to attempt to straighten the walls back to their original position over time.

What Are Wall Cracks
Cantey Foundation Specialists

Main reasons Foundation Walls Crack!

Curing Concrete
As concrete cures, it is common for small cracks to appear in foundation walls. These cracks are very common, and they’re not a sign of a major foundation problem. Shrinkage cracks tend to be very small “hairline” cracks that are usually 1/16″ wide or less. They generally occur near the center of a span and maintain a consistent width for the length of the crack. A Word Of Warning: Be careful not to assume that a crack in your foundation is merely a shrinkage crack! If you see cracks in your foundation walls, monitor them regularly. If the cracks widen enough that you can fit a dime in them, or one end of the crack grows wider than the other, you should consult a foundation contractor right away.

When the soils underneath your foundation fail to support the weight of your home, the foundation will begin to settle unevenly, and cracks will appear.

As vertical cracks form and the wall or corner of the house begins to rotate, you will typically see cracks that are wider at the top or bottom.

Foundation cracks that are caused by settlement are very serious, and they will only get worse over time as the home continues to move. If you are concerned that your foundation may be cracking due to settlement issues, it’s best to consult a professional right away.

If you have clay soils around your home, they can expand and contract significantly as they become wet.

Wet clay soils can expand enough to put literally thousands of pounds of pressure on a foundation wall. This can force the walls inwards, sometimes causing them to buckle and crack. Look also for walls pushing in at the bottom or tilting in at the top.

If left unrepaired, this kind of damage can worsen until the wall fails completely or is beyond repair. By addressing the problem of failing walls quickly, repairs can be completed in as little as a day.

Signs of Potential Issues from Wall Cracks

Stair-Step Cracks in Masonry

Cracks that follow the mortar joints in brick or block foundations and exterior walls, often indicating foundation settlement below.

Horizontal Cracks

Especially in basement walls, these often indicate significant pressure from the soil outside, causing the wall to bow or buckle.

Diagonal Cracks

Cracks that run diagonally up a wall, often originating from corners of windows or doors, suggest uneven settlement.

Widening or Lengthening Cracks

Any crack that is visibly growing in size or length over time.

Uneven Floors

Accompanied by sloping floors, dips, or bouncy areas.

Sticking Doors and Windows

Doors that jam, stick, or don't latch properly, and windows that are difficult to open or close, as their frames become distorted.

Gaps

Visible gaps between walls and ceilings or floors.

Bulging or Bowing Walls

Sections of basement or crawl space walls visibly pushing inward.

The Best Solution For The Problem

Foundation Piers, Wall Repair Systems & Crawl Space Supports to address various types of wall cracks stemming from structural issues, we utilize comprehensive and specialized solutions.

Foundation Push Piers

For cracks caused by foundation settlement, these heavy-duty steel piers are driven deep into stable soil or bedrock. They stabilize the foundation and can often lift the settled portion, thereby helping to close cracks in foundation walls and the upper structure.

Helical Piers

Similar steel piers with helical plates that are screwed into the ground to achieve stabilization. Used for foundation settlement, they also stabilize and can help lift foundations to reduce wall cracking.

GeoLock® Wall Anchor System

For bowing, buckling, or horizontally cracked basement and crawl space walls, these galvanized steel anchors use strong steel rods to connect the wall to earth anchors embedded in stable soil outside. When tightened, they stabilize the wall and can potentially straighten it over time, closing cracks.

CarbonArmor® and PowerBrace™

High-strength carbon fiber strips are bonded to the interior of cracking, bowing basement walls to prevent further inward movement. For more severe bowing, PowerBrace™ steel I-beams can be installed vertically against the wall, allowing for future adjustment and potential straightening.

SmartJack® Crawl Space Support System

For cracks in interior walls due to sagging floors over a crawl space, these adjustable steel support jacks are installed beneath floor joists and beams. They stabilize and lift the floor system, removing stress on interior walls and helping to close cracks.
CleanSpace

Crawl Space Encapsulation & Moisture Control

Addressing moisture in crawl spaces prevents wood rot and helps stabilize soil conditions, preventing wall issues caused by these factors.

Our Process for Repairing Wall Cracks

Thorough Inspection & Root Cause Analysis

A Cantey Foundation Specialist will conduct a detailed, multi-point inspection to accurately diagnose the type of wall crack and its underlying cause. This involves examining the crack pattern, the entire foundation, interior and exterior walls, and the crawl space or basement.

01

Customized Solution Design

Based on the diagnosis, we will develop a tailored repair plan. This plan will specify the most appropriate solution, whether it’s foundation piers, wall anchors, carbon fiber straps, SmartJack® supports, or a combination of these, to permanently address the structural issue causing the cracks.

02

Preparation and Installation

Our skilled crew will prepare the site and install the chosen system. This may involve excavating for exterior wall anchors or piers, preparing walls for carbon fiber application, or installing supports in the crawl space.

03

Structural Stabilization & Potential Realignment

  • For foundation settlement, piers are installed and typically used with hydraulic lifting equipment to stabilize and potentially raise the foundation, which can help close cracks in walls.
  • For bowing walls, wall anchors are installed and tightened to pull the wall back, or carbon fiber straps/steel I-beams brace the wall, preventing further movement and potentially closing cracks.
  • For interior wall cracks due to sagging floors, SmartJack® supports stabilize and lift the floor system, removing stress on the walls.

04

Site Restoration

After the structural repairs are complete, the work area is cleaned, and any excavations are backfilled, leaving minimal disruption. While we address the structural cause of the cracks, cosmetic repairs (patching drywall, painting) are typically handled by the homeowner or a separate contractor.

What types of wall cracks are serious?

While hairline cracks can be superficial, serious wall cracks often include: stair-step cracks in masonry, horizontal cracks in foundation walls, diagonal cracks, cracks that are widening or lengthening, or cracks accompanied by sticking doors/windows or uneven floors.
Yes. Cracks in basement walls, especially horizontal or vertical cracks, can be direct entry points for water, leading to leaks, moisture issues, and mold growth in your basement.
In most cases, yes. Our structural solutions are designed to stabilize the underlying problem (foundation, bowing wall, sagging floor) without extensive demolition of the walls themselves. Once the structure is stabilized, cosmetic repairs to the wall surface can be made.
Our structural wall repair solutions, including foundation piers, wall anchors, and carbon fiber straps, are designed to be permanent fixes. They come with robust, transferable warranties, ensuring long-term stability.
While our solutions effectively stabilize the structure and often cause cracks to close significantly or completely, especially if a foundation lift is achieved, some cracks may still require cosmetic patching by a finish contractor to become invisible. The primary goal is structural integrity.
