Foundation Crack Repair

Every home is going to have cracks in its foundation. What’s important is figuring out when a crack is simply the house settling or whether it’s an indication of something more serious.

Identifying the direction and size of any crack will help you determine whether it’s something you can fix on your own or whether you need to call in the experts.

Pay attention to the crack’s direction
If your crack is horizontal, then breathe easy. Usually horizontal cracks are the least troublesome. Vertical cracks or those in the shape of a staircase are more worrisome since they usually signal a more serious problem.

Size does count
The real test of any crack is its size and placement. Smooth, even hairline, cracks are usually not serious and a quick repair is all that is needed to prevent them from turning into something more serious. Any crack with an accompanying slant or bulge–in any direction–is serious. The same goes if the crack is large enough to put the tip of your pinky into or if it’s leaking water. These types of cracks need to be assessed by an expert before any repairs can be done. In this case we would call in our structural engineer

When horizontal cracks are a problem
Horizontal cracks are most common in concrete block and brick foundations, but they can also show up in poured concrete foundation. Usually they are the result of frost damage after freezing temperatures shrink the concrete, but they are also caused by excessive pressure on the foundation from wet soil. Long, horizontal cracks extending the full length of any outside wall should be investigated closely. A bulging crack can indicate a wall sliding off its footing or other stresses on a supporting wall.

Bowling Foundation Walls
Over time, concrete walls may start to buckle under outside pressure. Foundation anchors on the inside of the wall will prevent any further damage by adding additional support.

Basement Floor Cracks
Concrete floors can crack by sinking into soil, or by being forced upward by the soil itself. If your floor is heaving, there is also potential for damaging the surrounding walls. We can help identify the source of floor cracks and offer you a professional solution.

Heaving Foundations
Moisture, frost, and excess silt/clay can cause the soil underneath concrete floors & foundations to expand and cause damaging cracks. This is known as foundation heaving. Contact us today if you begin to see these types of cracks in your foundation.

Settling Foundations
Foundation settling can cause cracks and other types of damage to the exterior of your home. When the foundation sinks with the soil, your home absorbs the resulting effects. Cracked or broken exterior bricks as well as, chimney tilting are just some of the potential repercussions. However, a foundation pier system can correct this issue by transferring the excess weight deeper underground.

Foundation Wall Cracks
Wall cracks are usually a warning sign to more threatening problems with your foundation. Repairing both interior and exterior wall cracks begins with locating the primary structural problem and correcting the issue at the source. Only then, can the wall cracks be addressed.
