Crack Injection
Resin and grout injection that seals active leaks and restores monolithic strength.
The engineering brief
What crack injection involves
Cracks are injected either to stop water flow or to restore structural continuity — the objective determines the resin.
Polyurethane grouts seal actively leaking cracks; epoxy resins structurally weld dormant cracks back together.

Our process
How we deliver crack injection
Site Survey
Moisture mapping, substrate testing and photographic condition survey of every affected area.
Technical Proposal
Specification, system build-up, quantities and programme issued with consultant-ready documentation.
Surface Preparation
Mechanical grinding, shot blasting or high-pressure cleaning to achieve the specified profile.
System Application
Certified applicators install the approved system in controlled lifts with wet-film thickness checks.
Testing & Handover
Flood testing, adhesion pull-off tests, as-built records and a written warranty.
