A professional damp-proofing system designed to control rising damp in masonry walls in humid building environments — from diagnosis through restoration.
Rising damp shows itself in predictable ways — usually near floor level, and usually worse in the rainy season.
Paint film lifts and blisters as moisture pushes through from behind the surface.
White, powdery salts (efflorescence) crystallise on the surface as damp walls dry out.
Render turns soft, crumbly or hollow-sounding, often up to a metre above floor level.
A visible tide line or constantly damp band that returns no matter how often it's painted over.
Yellow-brown staining spreads across the lower wall, often with patches of salt where moisture evaporates.
Repeated wetting and drying darkens and cracks the render at the base of the wall until it begins to break down.
Masonry walls draw moisture up from the ground through tiny capillary channels within the block or brickwork — much like a wick drawing water upward. Without an effective barrier, that moisture keeps rising, carrying dissolved ground salts with it.
As the water evaporates from the wall surface, the salts are left behind — driving the paint failure, plaster damage and staining that homeowners notice first. The higher the moisture rises, the more restoration work is eventually needed.
A correctly diagnosed rising damp problem calls for a chemical damp-proof course — a barrier introduced into the wall itself, below the point damp is entering — paired with a wall reinstatement system designed to manage residual ground salts.
StopDamp+ is a professional rising damp treatment system for masonry walls. An advanced injection cream is injected into drilled holes in the mortar course to form a chemical damp-proof course inside the wall. BaseShield then protects the lower wall, and StopDamp+ Cement Mix, an anti-salt damp-proof additive, protects the new plaster. Together they form a proven long-lasting system.
StopDamp+ is for homeowners dealing with peeling paint, salt deposits or damp near the floor; building contractors and plasterers who need a reliable damp-proofing method; and property maintenance companies managing damp across several buildings. SoAqua Solutions supplies the products, offers diagnosis support and trains installers to apply the full system.
Injection Cream, BaseShield and StopDamp+ Cement Mix work together as a complete treatment — from establishing the damp-proof barrier to reinstating the wall above it.
A 310ml cartridge cream, applied with a caulking gun into drilled holes to establish the chemical damp-proof barrier within the wall.

Brushed on the wall, from floor level up, to help prevent moisture movement, ahead of reinstatement.

5 × Injection Cream cartridges, 1 × Cement Mix, BaseShield, caulking gun and drill bit — everything needed for a standard treatment run.
Explore product →Every StopDamp+ installation follows the same sequence — from removing damaged plaster to a finished, reinstated wall.
A treatment system engineered specifically to address capillary rising damp in masonry walls — not a general-purpose sealant.
Applied with a standard caulking gun for controlled, consistent dosing along the treatment line.
Injection, moisture shielding and reinstatement are designed to work together, not sold as disconnected products.
A clear, repeatable seven-stage process suited to sandcrete block and masonry construction.
Formulated for masonry performance in humid building environments.
Guidance from assessment through to reinstatement, backed by BBA Agrément certification.
A genuine StopDamp+ installation, not a staged demonstration.
A long, continuous run of internal corridor walls showing classic rising damp symptoms — tide-lined plaster, surface salts and recurring paint failure along ground-floor sections.
The full StopDamp+ sequence was applied along the entire run: damaged plaster removed, the injection line drilled and dosed, BaseShield applied to the lower wall, and the corridor reinstated with StopDamp+ Cement Mix.
