Concrete Piers

Concrete piers are too big and blunt to be driven deep into foundation soils, so they usually don’t extend to competent supporting soils. These piers can crack under pressure, and they often install unevenly or crookedly under your home.

To install concrete piers under a home, the soil will first need to be excavated from around your foundation. Short, 6″-8″wide concrete cylinders are then pushed into the soil on top of one another, strung together by a wire. Shims are then placed between the top of the concrete pier and the footing, then the soil is backfilled. Blunt, wide concrete cylinders are difficult to push deep into the ground, making it very difficult to extend them past the poor supporting soils under your home. Concrete can crack and break when under pressure, and even in response to temperature changes, making concrete piers a flimsy repair method. Additionally, there is nothing to guide the direction for the pier, and no guarantee that they will be installed straight. So how will they support your home?

Because of these and other reasons, very few companies will recommend this kind of approach.
