Waterproofing
Protect Your Structure From Water — Permanently.
Stop leakage, seepage and dampness for good.
Water is the number-one enemy of any building. Danchem provides professional waterproofing for roofs, terraces, basements, bathrooms, water tanks and swimming pools using tested materials and application techniques. We identify the true source, prepare the surface properly and apply the right system so leakage does not come back.

Every part of the job, covered.
Roof & Terrace Waterproofing
Liquid-applied membranes and cementitious coatings that stop rainwater seepage and resist harsh weather.
Basement Waterproofing
Protects underground spaces from groundwater and moisture using crystalline and membrane systems.
Bathroom & Toilet Waterproofing
Full sunken-portion and wall waterproofing so water never reaches the slab or the walls of the room below.
Water Tank Waterproofing
Food-grade, non-toxic coatings that keep stored water clean and prevent leakage from cracks and joints.
Swimming Pool Waterproofing
Watertight barriers that stop water loss and protect the concrete shell of the pool.
External Wall & Damp Proofing
Weatherproof coatings and rising-damp treatment that keep interior walls dry and paint-friendly.
Expansion & Construction Joints
Flexible sealants and jointing systems that let the structure move without letting water in.
Heat Insulation Coating
Reflective, insulating coatings on roofs that also reduce indoor heat and cooling costs.

Frequently asked.
How long does waterproofing last?
Depending on the system used, waterproofing typically lasts 7–15 years. Premium PU and polymeric systems on well-prepared surfaces can go longer.
Why does leakage come back after previous waterproofing?
Usually because the source wasn't traced correctly, or surface preparation was poor. We diagnose first, then choose the system — that's why our repairs last.
Can waterproofing be done on an old, occupied building?
Yes. Most waterproofing work happens on the external surface (terrace, walls) or specific rooms and doesn't require you to vacate the home.
Do you provide warranty?
Yes. We provide a written warranty on our workmanship, and pass on manufacturer warranties on the chemicals used.
