Our Services

Foundation Repairs
We assess and repair foundation issues—such as settling or bowing—using underpinning, helical piers, wall stabilization, and structural support systems.

Grading & Soil Preparation
We regrade soil and adjust slopes to divert surface water away from the foundation and address erosion risks before waterproofing begins.
Benefits of Our Foundation & Waterproofing Services
Dry, Healthy Basements
Interior systems intercept water and channel it to sump pumps before it causes damage.
Prevent Structural Failure
Crack injections and wall anchors stop bowing and restore load-bearing integrity.
Protection Against Soil Pressure
Grading and soil prep manage groundwater effects induced by heavy rain and clay soils.
Warrantied Workmanship
Many of our waterproofing and repair systems come with transferable lifetime warranties.
