We specialize in Polyurethane (PU) injection, a proven method for sealing active water leaks in concrete structures. PU injection is ideal for treating cracks in ceilings, walls, and slabs by injecting a high-pressure, expanding resin that fills voids and blocks water pathways from within.

For more persistent or severe leakage issues, we recommend a combined waterproofing system:

• PU injection from below to stop active leaks and seal internal cracks
• Flood infusion treatment from above to penetrate and seal the surface capillaries, enhancing waterproofing from the top layer down

This dual approach addresses both the source and the symptoms of water ingress, ensuring a more durable and long-term solution.

As part of our service, we also make good all affected ceiling areas, including plaster repair and repainting, to restore your property to its original condition with minimal disruption.

Our team ensures high-quality workmanship with a strong focus on clean execution, effectiveness, and customer satisfaction.
