In addition to above-grade retaining structures, SAGE designs many types of temporary and permanent shoring and underpinning systems for excavation support, settlement and deflection mitigation, foundation retrofitting, and subgrade/foundation repair.

Our experience in shoring and underpinning design and field support makes SAGE uniquely qualified to accommodate challenging conditions such as difficult soils, unusual or large surcharge loads, little or no right-of-way, or nearby utilities.
