Repairing Foundation Wall Leaks

National/American was contracted to diagnose and provide a solution to a recurring foundation wall leak on a townhouse building in Central New Jersey. The repair was a turnkey operation from design, utility mark-outs, waterproofing and drainage repairs to excavation and backfilling. Working within a two-day weather window we repaired faulty waterproofing, removed a former repair,  replaced footing drains, sealed utility penetrations and reconfigured underground leader pipes. This precision excavation is a precursor to dozens of interior basement repairs.
