Cutting-Edge Moisture Technology & Equipment

Our Residential Waterproofing Services & Methodology

Complete, permanent exterior basement waterproofing requires meticulous foundation excavation. This involves carefully removing the soil trenching deep down alongside your home’s foundation footers.

When you trust the trained, highly professional team at T&T Waterproofing & Drain Tile, we ensure the structural excavation is done with immense care to avoid any property damage.

  • Complete Excavation: We safely dig down to expose the bare concrete or block exterior.
  • Structural Repair: Once the foundation walls are fully exposed, any settling cracks, bowing, or damaged block seams are structurally corrected and bonded.
  • Membrane Application: A thick, industrial-grade positive-side waterproof membrane is seamlessly applied to the exterior concrete to permanently seal out groundwater.
  • Drainage Integration: We optionally lay an exterior Drain Tile System at the footer base to channel water miles away from the home.
  • Backfill & Tamp: We carefully backfill and grade the soil to maintain positive watershed away from your structure.
