When it comes to foundation wall cracks, it’s important to understand the root cause and whether it presents a danger to your home’s foundation and structural integrity.

If you have horizontal or vertical wall cracks, “stair-step” or diagonal cracks or bulging, buckling or bowing foundation walls, your home could be in need of foundation repair. Foundation wall cracks can occur for a variety of reasons, and each type has its own unique solution. 

For hairline cracks caused by the concrete curing process, often no repair is necessary. However, foundation walls cracking due to foundation settlement issues or expansive soils may require some repair work. At Thrasher, we’re experts in foundation and concrete repair - so no matter the problem, we’ve got a solution. To choose the right products to permanently stabilize your home’s foundation, we perform a thorough inspection of your property. After that, you can expect a thorough explanation of the foundation crack repair solution we propose and why.

Frequently Asked Questions

  • Cracked and uneven concrete that remains unrepaired will only get worse over time. In the short term, sunken or heaved concrete slabs present tripping hazards that you may be liable for as a homeowner. In the long term, without repair and proper sealing, the concrete will continue to crack and crumble, eventually requiring replacement. Properly maintaining your concrete by repairing and sealing cracks will extend the life of your concrete for years to come. 

  • When it comes to foundation crack repair, there are several factors we consider before proposing a solution, such as the location and size of the foundation cracks. At Thrasher, we’re experts in both foundation repair and concrete repair and maintenance. So, when we visit your home for the first time, you can expect a thorough inspection and a thorough explanation of the foundation crack repair solution we propose and why. 

  • NexusPro is a silicone-based sealant for joints and cracks specially engineered to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. Plus, the drying time is a fraction of that needed for other urethane-based caulking products.

  • If the cement is sinking or unlevel, we use PolyLevel® polyurethane foam to lift and level the concrete. Then, your cracked concrete and control joints are filled and sealed using NexusPro joint sealant. When we install NexusPro, we prepare and clean the concrete cracks, insert the product and then finish it off with native sand to give the whole surface a clean, finished look. Finally, the whole surface is protected from the elements with a coat of SealantPro™, which permanently bonds to your concrete. 

  • Foundation wall cracks and the impending structural damage is caused by the soil surrounding your home. When the soil absorbs water during wet, rainy seasons, it expands. Conversely, the soil will shrink during dry seasons and droughts. This pattern of expansion and contraction puts enormous pressure on the foundation walls, and can cause the foundation to crack, heave and shift. Poured basement walls typically fail from the top corners inward, resulting in longer diagonal cracks that emanate from the corners of the foundation wall. Block foundation walls most often fail horizontally in the middle, bowing in as the mortar joints break. The evidence of a failing foundation block wall, then, will usually consist of horizontal foundation wall cracks midway up a basement wall. You may also see stairstep cracks as the joints fail around concrete blocks at different levels. If you do see foundation wall cracks of this type, don’t panic — most foundations can be stabilized and even lifted back to their original position using specialized equipment. This is often less expensive and far less disruptive than total foundation repair.

  • Concrete can crack over time, often early on in its lifespan as it cures and shrinks. So, if you find a short, often vertical, hairline crack in your foundation wall — especially if it occurs near the seam where the forms were joined for the initial foundation pour — it may be nothing to worry about. However, foundation wall cracks can also be a sign of structural damage caused by the expansion and contraction of the soil surrounding your home. The pressure from expanding soils can cause your foundation to crack, heave and shift. Foundation cracks that are caused by settlement are very serious and will only get worse over time as the home continues to move.
