Seasonal rainfall, storm events, and periods of sustained moisture cause soil saturation around Wilmington, NC foundations โ which creates hydrostatic pressure that pushes water through even small cracks and porous concrete over time.
Our Wilmington, NC team designs waterproofing solutions specifically calibrated to the rainfall intensity and soil saturation patterns present in this part of NC.
Clay-heavy soils found in many NC communities retain water and increase lateral pressure against basement walls. Sandy or silty soils drain faster but can shift and undermine footings over years.
