Solid cement wall cracks
Most solid cement foundation wall cracks are not structural and only present a nuisance when leaking.
Leaking Foundation Crack Repairs
At Basement Waterproofing Solutions we have been repairing leaking foundation cracks for many years with a flexible repair system. This type of repair allows for crack movement and keeps your basement dry. Some epoxy injection systems developed in the late 70s attempted to seal the crack with a strong none flexible epoxy that was designed to eliminate all movement. We found this type of repair to be only temporary. Basement Waterproofing Solutions has repaired many of these failed crack repairs with our flexible system with a tremendous success rate.
When concrete dries, it has tendency to shrink sometimes causing a shrinkage crack. These cracks are very small like a fracture and usually start closer to the floor and do not crack completely up to the top of the foundation. These cracks are none structural and are easily repaired due to no additional movement from settling
These cracks, like shrinkage cracks do not present a structural situation or problem. They are generally wider at the top then at the bottom. Most settling cracks span completely from the top of a foundation to the bottom but in some instances, may not complete their way to the bottom of the foundation. Due to the continuous movement of expansion, contraction and settling, these cracks can be a bit more of a challenge to repair for a none professional.
These are horizontal seams sometimes on a slight angle up or downward. They are created during the construction of the foundation when the concrete is being poured into the wall forms. Sometimes there is a delay between truckloads of concrete. The 1st trucks concrete begins to harden before the next truck can dump its concrete causing a seam that can leak.
Structural cracks are defined as any crack that has jeopardized the structural integrity of a foundation. Generally there is a buckling, bowing or bulge within the foundation wall or a shifting of a certain section of the wall. In many cases it is difficult to see a bow in a foundation wall viewing it face to face but if you stand at one end of the wall with your head close to the foundation, you will be able to see if the wall is bowing when looking down the full length of the wall. Most structural cracking situations occur on block, brick or stone foundations but can also take place on a solid cement wall. Structural cracks usually run horizontally but can also run vertically. Horizontal cracks that cause the foundation to bow inward are usually caused by ground expansion from winter freeze/frost. In most cases excavating the entire exterior of this wall will allow the wall to flex back into its original position.
For over 30 years we have been installing steel reinforcement beams up against bowing foundation walls to prevent additional damage. We strictly follow an engineer’s plan that was designed for our specific needs back in the 80s.
Since then, we have adapted to industry changes and now offer the latest Carbon fiber technology for structural foundation crack repairs. We will design a custom plan utilizing steel beam construction or carbon fiber to suit the exact needs of your foundations structural situation.
