Soil Conditions & Foundation Types in Hempstead, NY

The soil composition common in this part of NY directly determines how water behaves near foundations. Clay-dominant ground conditions, which are prevalent throughout much of NY, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time. Understanding what you're dealing with underground changes everything about what solution will actually work.

Structures predating modern waterproofing codes frequently have drainage systems that weren't sized for current rainfall intensity.
