PU / Epoxy Injection
Targeted resin injection that seals active cracks and stops leaks.
PU and epoxy injection is a precise repair method that seals leaking cracks by injecting resin directly into the defect.
What Is PU / Epoxy Injection?
When water is leaking through a crack, injection delivers the solution exactly where it is needed. Polyurethane (PU) resin reacts with water and foams to fill and seal active, wet cracks. Epoxy resin is rigid and high-strength, used where the crack also needs to be structurally bonded back together. The correct resin is selected based on whether the crack is moving, wet or structural.
Common Applications
Injection is used to stop leaks in basement walls, water tanks, lift pits, retaining walls, construction joints and any concrete crack that is actively passing water.
Key Benefits of PU / Epoxy Injection
- Seals leaks at the source
- PU resin works in wet, active cracks
- Epoxy resin restores the structural bond
- Minimal disruption — no demolition needed
- Effective where surface coatings cannot reach
