Rising Damp & Mould Treatment
Treat rising damp and mould at the source — without demolishing your walls. Our chemical DPC injection system works inside the wall's masonry structure, not just on the surface.

What is Interior Wall Waterproofing?
Interior wall waterproofing addresses moisture that enters your home from below (rising damp) or through the wall fabric from outside. Unlike exterior treatments that work on the wall face, interior systems work within the wall itself — cutting off the moisture pathway at its source and stabilising the affected masonry for the long term.
The core treatment for rising damp is chemical DPC (damp-proof course) injection — a silane/siloxane cream injected into drilled holes along the base of the wall, where it cures into a continuous waterproof barrier inside the masonry. Above the DPC level, cementitious waterproofing slurry replaces the contaminated, salt-damaged plaster with a breathable, waterproof finish layer.
Where mould is present, a biocidal primer kills active spores and prevents regrowth for years — crucial during Kanpur's humid monsoon months when mould spreads rapidly on damp surfaces. All products used are safe for occupied residential and commercial spaces.
Signs You Need Interior Treatment
- ✓Tide marks or staining on lower sections of interior walls
- ✓Paint peeling from the bottom upward on inside walls
- ✓Persistent musty or earthy smell in rooms
- ✓Visible black or green mould patches on walls or ceiling
- ✓White salt crystals forming on plaster surfaces
- ✓Walls feel damp or cold to the touch even in dry weather
Our Process
Our 5-Step Approach
Rising damp cannot be fixed with paint alone — a correct diagnosis and systematic treatment is the only lasting solution.
Moisture Mapping
Electronic moisture meter readings taken at 300 mm intervals across all affected walls, building a precise map of damp zones, tide marks, and saturation levels to plan the treatment.
DPC Injection Points
Injection holes drilled at 120 mm intervals along a horizontal band 150 mm above floor level — the correct height to intercept rising damp before it climbs higher into the wall.
Chemical Injection
Silane/siloxane DPC cream injected under low pressure into each hole, filling the wall's capillary network and polymerising in situ to form a continuous chemical damp-proof course.
Cementitious Slurry Coat
Salt-contaminated plaster removed to a height of 1 m above the tide mark. Fresh salt-resistant cementitious slurry applied in two coats to re-plaster and waterproof the wall surface.
Mould-Inhibiting Primer
Biocidal, zero-VOC mould-killing primer applied over cured slurry. Safe for occupied rooms, this primer suppresses mould regrowth and provides the ideal base for finish paint.
