What is Chemical Injection Waterproofing?
Chemical injection waterproofing seals water paths by delivering reactive gels into cracks, voids, and porous concrete without structural disruption. These chemicals react with moisture and expand, sealing the leakage paths from within and forming a permanent, flexible barrier against water ingress. This technique is especially suited for structures where traditional surface-based waterproofing is not feasible, such as:
- Basement walls and floors
- Underground car parks and tunnels
- Water tanks and sewage chambers
- Podium slabs and expansion joints
- Retaining walls and lift pits
- Roof slabs and wet areas
