Many foundation contractors provide free evaluations of foundations; however, they are in the business of selling you piers. As engineers, we have no incentive to sell you unnecessary repairs.

It is not uncommon to have a crack in your foundation; even new homes can have foundation cracks. Typically foundation cracks under 1/16 of an inch do not have a significant impact on the performance of the foundation. However, cracks 1/8 of an inch or larger may weaken the slab. Larger foundation cracks can be repaired by injecting structural epoxy. The bonding strength of some epoxies can actually be stronger than the concrete.

The majority of foundations built in Dallas Fort-Worth are built on expansive clay soil. The soil will expand and contract with changes in the its moisture content, causing the foundation to move. The more consistent the moisture remains in the soil, the less movement will occur in the foundation.
