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.
The efficiency and work ethic of your staff is reflected in the finished product of which we are totally satisfied.
