A 1,000 square foot roof sheds 623 gallons of rainwater from one inch of rainfall offering you the opportunity to collect thousands of gallons of “free” water for reuse in your garden.
Winter snow ground thaw and late winter rains can lead to higher ground water conditions, which can create foundation wall and below slab water infiltration.
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.
“I have tremendous respect for National/American Waterproofing and [owner] Bill Hoffman. The intangibles he brings to the job are limitless. He stands by his product, he stands by his crew, and he runs a tight ship. There’s nothing else I could ask for.”
