The Problem

The signs are on your wall already.

Rising damp shows itself in predictable ways — usually near floor level, and usually worse in the rainy season.

01

Peeling paint

Paint film lifts and blisters as moisture pushes through from behind the surface.

02

Salt deposits

White, powdery salts (efflorescence) crystallise on the surface as damp walls dry out.

Damaged plaster

Render turns soft, crumbly or hollow-sounding, often up to a metre above floor level.

Understanding the Problem

What is rising damp, really?

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.

The StopDamp+ System

One coordinated system, not a single product.

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.

Stage 1

Injection Cream

A 310ml cartridge cream, applied with a caulking gun into drilled holes to establish the chemical damp-proof barrier within the wall.

Stage 4

BaseShield

Applied to the lower wall to block lateral moisture movement below the new damp-proof line, ahead of reinstatement.

How It Works

Six stages, one continuous process.

Every StopDamp+ installation follows the same sequence — from removing damaged plaster to a finished, reinstated wall. See the full installation guide →

01

Hack Off

Damaged, contaminated plaster is removed from the affected area to expose sound masonry.

02

Drill

A line of holes is drilled into the wall at the correct height and spacing to receive the damp-proof injection. Drill holes are then cleared of dust for better injection uptake.

03

Inject

StopDamp+ Injection Cream is applied into each hole using a cartridge and caulking gun, forming the chemical damp-proof course.

04

Baseshield

BaseShield is applied to the lower wall to block lateral moisture movement below the new damp-proof line.

05

Cure

The treated wall is left to cure, allowing the barrier to establish fully before reinstatement begins.

06

Replaster

The wall is reinstated using StopDamp+ Cement Mix, ready for final decoration.

Why StopDamp+

Built for the way masonry walls behave here.

✓

Designed for rising damp

A treatment system engineered specifically to address capillary rising damp in masonry walls — not a general-purpose sealant.

✓

Cartridge application

Applied with a standard caulking gun for controlled, consistent dosing along the treatment line.

✓

A complete system

Injection, lateral shielding and reinstatement are designed to work together, not sold as disconnected products.

✓

Practical installation

A clear, repeatable six-stage process suited to sandcrete block and masonry construction.

✓

Appropriate for local conditions

Formulated for masonry performance in humid building environments.

✓

Technical support

Guidance from assessment through to reinstatement, backed by BBA Agrément certification.

Anchor Project

A 255-metre corridor treatment

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.

Diagnosis First

Not every damp wall is rising damp.

Treating the wrong cause wastes time and money. Here's how to tell the difference.

Rising Damp

  • Concentrated near floor level, rarely above ~1m
  • Tide-line staining, often with salt deposits
  • Present year-round, worse in wet season
  • Treated with a chemical damp-proof course

Penetrating Damp

  • Can appear at any height on the wall
  • Linked to a specific defect — cracked render, leaking gutter, poor pointing
  • Often localised to one patch or wall
  • Treated by fixing the source defect

Condensation

  • Common in poorly ventilated rooms — bathrooms, kitchens
  • Surface moisture, black mould, no tide line
  • Changes with season and ventilation habits
  • Treated by improving ventilation, not injection
