Cracked Walls

Due to the fact the soil in Eastern Iowa and Western Illinois is primarily clay, which expands and contracts with the changes in the moisture levels and temperatures, many foundations will be weakened by this and crack. This crack then becomes an aggravating leak. How do we fix this?

Crack in Cinder Block Foundation

This foundation type typically was used in the 1960’s through the 1980’s. Once the basement is waterproofed and relief/weep holes are drilled at the base of the wall, there will be no more pressure, so water should not leak through the cracks. Cinder block walls are hollow, thus they cannot hold water if it is drained out of them! However, if the customer prefers, we can use mortar repair to fill these cracks in for aesthetic purposes. Some customers also have us apply a heavy duty moisture sealant to keep the block completely dry after the waterproofing work is completed.

Unstable cinder block walls will often continue to cracked if not reinforced. If you have cracked cinder block walls, this is often a symptom of bowed walls which can require a specific bowed walls solution.

Crack in a Poured Concrete Foundation

Urethane Crack Injection Repair

This foundation type typically has been done since the late 1980’s. It usually cracks vertically and a hairline type crack appears. These cannot be repaired using any type of hydraulic cement, caulk, or waterproof paint because there is too much pressure for these materials to hold and eventually the leak will reappear. However, a successful urethane injection can solve this issue. On the inside of the basement a 2-part epoxy material is used to cover the crack and injection ports are set approx every 8″-12″ up the face of the crack. Once the patching material hardens, urethane is injected into the ports. Urethane, when injected expands with the presence of moisture filling up the entire area.    The urethane travels the width of the crack from the inside out. The earth on the exterior keeps the urethane from escaping on the outside, and the patching material keeps it from oozing out on the inside. The urethane sets up very quickly and the wall crack is sealed from the inside out. No more water! Lastly, Urethane once it is set up has elasticity which will ensure the repair will last for a long time.

Epoxy Crack Injection Repair

Epoxy is used to repair cracks which are structural. Epoxy injections are most often done in conjunction with counter sunk staples for added reinforcement.  As mentioned above, urethane is used to repair cracks which are not structural cracks.

Waterproof Paneling

In cases where the foundation has several cracks we can affix a waterproof paneling, which is more cost effective than injecting all the cracks. The paneling will also protect against any future cracks that may develop.

Fortress Stablization Systems Carbon Fiber Countersunk Staples

In cracked foundations that are not primarily vertical, a more advanced repair system than urethane injection needs to be implemented. We use Fortress Stabilization’s Carbon Fiber Countersunk Staples to repair these more complex foundation issues.
