Solution

Basement Waterproofing & Tanking

Complete basement protection against hydrostatic pressure, monsoon water, and rising damp. Interior or exterior systems. Built to keep basements dry for 20+ years.

The Challenge

  • 💧
    Hydrostatic Pressure

    Water exerts pressure from below and sides. Simple sealers fail under sustained pressure from underground aquifers or heavy monsoon infiltration.

  • 🌧️
    Monsoon Conditions

    Seasonal flooding and heavy rain create wet environments that standard paints and membranes can't handle.

  • 🧂
    Salt & Efflorescence

    Damp concrete develops white salt deposits and mold. Cheap waterproofing doesn't prevent salt migration.

  • 🏗️
    Structural Integrity

    Water damage leads to rebar corrosion and concrete degradation. Prevention is cheaper than repair.

Two Approaches

🏠 Interior Tanking

Apply waterproofing membranes on the inside (easier, less disruptive). Works for most residential and commercial basements. Requires good drainage to prevent water buildup.

  • ✓ Cost-effective
  • ✓ Faster installation
  • ✓ No excavation needed
  • ⚠ Requires external drainage

🏛️ Exterior Tanking

Protect concrete from outside with membranes and drainage. Best for new construction. Prevents water from reaching concrete entirely.

  • ✓ Most durable long-term
  • ✓ Stops water at source
  • ✓ 25-30 year lifespan
  • ⚠ Requires excavation
