Foundation Types Common in Old Westbury, NY Properties

The soil composition around Old Westbury and Old Westbury, NY properties affects how quickly water intrusion happens and from which direction. Clay-dominant ground conditions, which are prevalent throughout much of NY, retain moisture longer and create sustained lateral pressure against foundation walls. Understanding what you're dealing with underground changes everything about what solution will actually work.
