Concrete leak sealing & injection · SEQ
We stop water coming through concrete.
Cracks, construction joints, lift pits, car park slabs, retaining walls and planter boxes — sealed from the dry side, without excavating. And when injection is the wrong answer, we tell you that instead of selling it to you.
Mon–Fri 07:00–17:00. Send photos any time — out of hours you will get a call first thing.
FIG. 1 — Negative-side injection through mechanical packers. The holes are drilled at an angle and offset from the crack so they meet it at depth; the resin fills the crack from inside the wall rather than being smeared across the face.

Before you ring anybody
Is injection even the right fix?
Often it isn't. Resin injection seals a defined path through concrete — a crack, a joint, a tie hole. It does nothing for a blocked ag line, a failed membrane, condensation, rising damp, or a wall that is still moving. Injecting any of those wastes your money and makes the real repair harder.
We have written up the fifteen situations where we will tell you not to inject, along with who you should call instead. Several of them send the work away from us.
Fifteen times we'll tell you not to injectWhat we run, and when
Polyurethane injection, in two grades. Which one comes down to a single question: will this crack ever dry out permanently?
- Hydrophobic PU
- Active leaks, and cracks that dry out over winter
- Hydrophilic PU
- Elements that stay wet all year round

Send three photos. We'll tell you what it is.
The whole wall, the wet area close up, and the ground outside on the other side of it. That is usually enough to identify a leak without anyone attending — and enough for us to tell you honestly whether this is our job or somebody else's.
