Rainfall, Storms & Seasonal Moisture in Hempstead, NY

Foundation Types Common in Hempstead, NY Properties

The ground conditions around Hempstead and Hempstead, NY properties shapes how moisture moves and builds pressure underground. Clay-dominant ground conditions, which are prevalent throughout much of NY, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time. Identifying your specific soil type is why our assessments start outside the building, not inside the basement.
