The Waterproofing Specialists Behind TheSealExperts

TheSealExperts exists to do one thing exceptionally well: keep water where it belongs. Under the umbrella of Kaisha International, we manufacture and supply a complete range of injection resins, protective coatings, grouting machines, dispensing guns and injection packers for waterproofing and structural repair.

From a leaking basement to a tunnel, a terrace to a water-retaining tank, our products are engineered to seal water at its source and to be used together as a coherent system. We work closely with applicators and engineers — and we back every product with technical guidance and free samples so you can trial before you commit.
