Service 03
PU Grouting
Polyurethane injection grouting solutions for treating water leakage through cracks, construction joints and concrete structures where suitable.
Overview
PU Grouting
When water is actively leaking through a crack, a joint or honeycombed concrete, surface coatings alone are rarely enough. Polyurethane (PU) injection grouting seals the leak path from within.
Injection packers are drilled into the concrete along the crack and PU resin is pumped under pressure. The resin reacts with water, expands and forms a flexible, watertight seal deep inside the structure.
Benefits
What you can expect.
Stops active leaks
Water-reactive resins work even when the crack is wet or flowing.
Minimal demolition
Treatment is carried out through small drilled ports rather than large-scale breaking.
Flexible seal
Elastic PU accommodates small structural movement without re-cracking.
Our process
- 01
Site inspection
We map the crack or joint, check how active the leak is and confirm that PU grouting is suitable.
- 02
Surface preparation
Ports are drilled at calculated angles and spacing; injection packers are fixed along the leak path.
- 03
Professional application
PU resin is injected under controlled pressure until the leak path is filled.
- 04
Quality check & handover
Packers are removed, holes are sealed and the area is checked for any residual seepage.
