Polyurethane Resin & Epoxy Injection

Waterproofing Solutions Australia only uses the best products available for crack injection waterproofing. We work with both polyurethane and epoxy resin injection systems, sourced from leading Australian injection suppliers and selected to suit the crack and the job.

Polyurethane resins are flexible and water-reactive — ideal for active water ingress, expanding on contact with water to seal the crack and accommodate minor movement without losing their seal.

Epoxy resins cure rigid and high-strength — used where the crack is non-moving and structural integrity needs to be restored, bonding the concrete back together rather than just sealing it.

Which system we use comes down to whether the crack is still moving, whether water is actively coming through, and whether the repair needs to be structural — not a one-size-fits-all approach.
