Basement leakage problems we solve
Identify your issue and see exactly how Sunroof fixes it – permanently.
⚠️
Signs your basement needs waterproofing
Don’t ignore these – they get worse over time
- Water seeping through walls or floor after rain
- Damp or consistently wet basement floor
- White salt deposits (efflorescence) on walls
- Mold, fungus, or persistent musty odour
- Cracks in foundation walls or floor slab
- Standing water after heavy monsoon rainfall
- Peeling paint or plaster on basement walls
- Rust stains from reinforcement bars showing through
⚠️ Ignoring basement leakage weakens the building foundation and leads to costly structural repairs. Early treatment saves significantly more money.

Methods & Process
Our basement waterproofing methods
We select the right system based on your basement type, leakage severity, and construction stage.
01
Best for active leaks
PU Injection Grouting
High-pressure polyurethane resin is injected directly into active cracks. The resin expands on contact with water, permanently sealing the leak even under hydrostatic pressure. No excavation needed.
02
Best for damp walls
Cementitious Waterproofing
Rigid, cement-based waterproof coating applied to internal walls and floor slab. Bonds chemically with concrete to block capillary water movement – ideal for existing basements without excavation.
03
Best for new construction
Membrane Waterproofing
Polymer-modified bituminous or HDPE membrane applied externally during construction or excavation. Provides a continuous barrier against groundwater, soil moisture and hydrostatic pressure.
04
Best for RCC structures
Crystalline Waterproofing
Chemical crystals penetrate deep into concrete, blocking pores and capillaries permanently. A self-healing system that reactivates whenever water is present – lifetime protection for RCC basements.
