Foundation Repair

A cracked foundation is a compromised building and hazardous living situation. We will repair the cracks in your foundation that permit the penetration of water in order to promote the structural integrity of your home.

The Foundation Types We Work With Are:

Poured Concrete Foundation

Poured concrete is prone to wall cracks. These wall cracks can look like lightning bolts and can allow water from the outside to come in. The most professional way to fix these cracks is to grind them out into a V-shaped groove, inject epoxy into the crack cleanly and finish the injection smooth to the foundation with hydraulic cement. The reason we grind the crack out further is to get as much epoxy into the crack as possible.

Depending on the state of the crack, it may be necessary to fix it from the outside using the same method. If this work is performed from the outside, we use tar to cover the hydraulic cement and then install thick 90 mil rubber over that. Once soil is backfilled the rubber protects tar, the tar protects hydraulic cement and the cement protects the epoxy.

Any type of foundation wall that is suffering from moisture problems would benefit from a french drain to help alleviate hydrostatic pressure and prevent further cracking and deterioration.

Cinderblock Foundation

Cinderblocks are hollow on the inside only giving vertical, not horizontal strength. They are prone to stair cracking, horizontal cracking, or vertical cracking which can compromise the structural integrity of the house. The most economical way to deal with structural compromised block wall is to install wall pins. Wall pins are installed by flooding the core pockets or core cavities with high PSI concrete (reinforced by steel rebar) that spans from the floor to the top of the foundation wall. Sometimes this work can be performed from the outside. Now there are other methods such as steel high beams or carbon fiber straps—these can be a remedy but they can also be an eye sore. 


Stone Foundation

Water is a natural solvent and as it sits against a stone foundation, over time the mortar between the stones begins to wear away. The mortar then turns to white powder and it falls right off, which is called efflorescence. One way of dealing with this is through a process called roughcasting, which is a similar process to stucco work. The main difference is that roughcasting will have a reinforced vapor barrier behind the roughcasting to block future moisture from deteriorating new finish. You will need to also install a modern french drain to do this. Why? Because gravity will naturally carry the water down and without the french drain, the water will build up and cause damage to your basement.

If the cost of roughcasting is too high, one alternative which is more cost effective but doesn’t last as long would be parging the wall. Parging is simply putting a new skim coat of concrete on top of the stone wall. This will eventually deteriorate over time as there is no vapor barrier.
