Robbins and Company utilizes the Grip-Tite Push Pier System for structural foundation repair where the actual foundation is lifted and supported by large steel brackets that slip under the foundation footing. Each bracket is supported by a steel tube hydraulically driven down to bedrock or proper load bearing strata, stabilizing the foundation and preventing further settling. Each pier is individually anchored and tested for successful load bearing.

Grip-Tite has over 70 years of experience invested in developing a superior product. The engineered design has passed the rigorous testing required to obtain a legacy report from the International Code Council.
