Basement Waterproofing & Foundation Repair in Mercer County, NJ

Protecting Mercer County Homes Since 2006

Mercer County presents a wide range of waterproofing and foundation challenges due to flat terrain, clay-heavy soils, slow drainage, groundwater pressure, and a mix of older and newer housing stock. Homes throughout the county can experience basement seepage, crawl space moisture, settlement, foundation cracking, and long-term moisture-related structural deterioration.

Low-lying areas near the Assunpink Creek, the Delaware River corridor, and sections influenced by Millstone River tributaries can experience elevated groundwater during wet periods. In other neighborhoods, poor grading and runoff patterns can keep water collecting close to the home, increasing hydrostatic pressure against basement walls and floors.

Whether your home is in Hamilton Township, Robbinsville, Lawrenceville, Pennington, East Windsor, or elsewhere in Mercer County, Down Under Waterproofing provides reliable, long-term solutions for basement waterproofing, foundation repair, crawl space encapsulation, masonry repair, stucco repair, above-grade waterproofing, construction restoration, Bilco doors and egress windows, and retaining walls.
