Get Exterior Basement Waterproofing | Interior Basement Waterproofing. Basement waterproofing is the professional process of preventing water intrusion and moisture buildup in your home’s lowest levels. It combines exterior and interior methods—such as high‑performance waterproofing membranes, foundation waterproofing systems, precision **** injections, and drain tile installations—to form a complete moisture barrier. Our process begins with a detailed inspection using moisture meters and video camera diagnostics to identify leaks, cracks, and hydrostatic pressure points. We then apply durable coatings and install sub‑slab drainage or perimeter drain systems. Finished with a sump pump installation when needed, this comprehensive approach stops flooding, inhibits mold growth, and protects against long‑term structural damage—all backed by our 25‑year transferable warranty.
