Hydrostatic pressure from saturated soil is what cracks concrete and pushes basement walls inward. Upper Merion’s clay soil makes this worse because clay holds water and creates constant pressure against your foundation. A French drain eliminates that pressure by moving water away before it saturates the soil.
If your foundation is already compromised, we’ll tell you during the inspection. You might need crack repair or structural reinforcement before or alongside your drainage installation. We work with structural engineers when needed and give you honest assessment of what your home requires.
