About This Service
Injection grouting seals water paths inside the concrete rather than coating over them. Polyurethane resins react with water and expand to shut off active leaks in seconds, while epoxy resins structurally rebond cracked concrete. Because it works from the inside face, injection is often the only practical fix for basements, tunnels, lift pits, and joints where excavation is impossible.
It is a skill trade: drilling pattern, packer placement, resin choice, and pressure all decide whether the leak actually stops. Our injection technicians are trained on the systems we install and carry out verification checks after every treatment.
What’s Included
An injection treatment is precise and localized. The scope typically includes the following.
- Leak path tracing and crack mapping
- Drilling and packer installation along the defect
- PU resin injection for active water stoppage
- Epoxy injection for structural rebonding
- Construction and expansion joint treatment
- Packer removal, patching, and verification
Key Benefits
PU resins expand on contact with water and seal running leaks immediately.
Treats below-grade leaks entirely from the inside face.
Epoxy systems restore monolithic strength across cracked sections.
Only the defective metre is treated, keeping costs proportionate.

Questions We Get Often
Water is actively running through a crack. Can that be sealed?
Yes. Water-reactive PU resin is designed exactly for that: it chases the water path, expands, and shuts it off, often within minutes of injection.
Is injection a permanent fix or a temporary one?
Correctly executed injection with the right resin is a permanent repair for that path. We verify after treatment and it is covered by our warranty.
Can you inject leaking joints between two structures?
Yes, construction and movement joints are among the most common injection targets, using flexible resins that tolerate ongoing movement.
