Leak Injection
Water ingress and moisture leads to significant damage, particularly in buildings lacking proper waterproofing.
Common problem areas include construction joints, movement joints, service penetrations, cracks, and compromised concrete.
We specialise in leak injection remediation waterproofing which addresses these vulnerabilities to extend the service life of your structure.
Our skilled operatives have extensive experience across a wide range of remedial applications, including:
Attenuation Tanks
Underground Car Parks
Tunnel Works
Bespoke Structures
Structural Repairs
WetGuard ensures that project- specific injection materials are selected and applied effectively.
Problems we solve
Our Technique
Our remedial services are tailored for each specific structure and typically include:
Targeted injection systems
Specialised grouting techniques
Crack repair and joint sealing
Waterproofing reinforcement for defective areas
Our targeted injection involves:
Drilling angled holes (typically at 45°) on both sides of the joint to intersect at the midpoint
Injecting water-reactive resins into the joint, allowing them to fill voids and seal active leaks
We use RASCOflex AY108 Acrylic Resin Gel, a soft but compact gel that expands on contact with water. The resin does not bond to concrete but creates a waterproof seal by increasing in volume, effectively displacing water and preventing further ingress, even under pressure.
Once the leak path is fully sealed under pressure, packers are removed and the injection points are patched.
