What is Box Type Waterproofing?
Box type waterproofing involves treating all six sides (four walls, floor, and ceiling/top) of an enclosed structure to create a complete waterproof enclosure—like sealing a box from all sides.
The Problem
Underground structures like basements, lift pits, and water tanks face water pressure from all directions. Single-side waterproofing is insufficient as water finds alternate ingress pathways.
Scientific Method
Comprehensive treatment sequence:
- Surface preparation (cleaning, crack repair)
- Application of waterproofing membrane on all internal surfaces
- Special attention to corners and joints
- Multiple coats with proper curing between layers
- Protective render or tile finish
Application Areas
- Underground water tanks (potable & non-potable)
- Lift pits and elevator shafts
- Basement parking areas
- Swimming pool structures
- Pump rooms and sumps
Benefits
- Complete water ingress prevention
- Handles high hydrostatic pressure
- Suitable for potable water contact
- Long-term structural protection
