Hydrophobic PU foam
Reacts with water on contact, expanding to seal the leak path within minutes.
Injection & Repair
Leak Sealing Injection UAE
Polyurethane injection for active water leaks.
Leak-sealing injection stops active water ingress in cracks and joints from the inside of the structure. A water-reactive polyurethane foam is injected through packers to block the flow path, followed where required by a flexible resin for a permanent, elastic seal — no excavation of the outer face is needed.

Overview
Hydrophilic and hydrophobic polyurethane resins are injected into actively leaking cracks and joints — reacting with water to expand and form a flexible, watertight seal under hydrostatic pressure.
Systems & specifications
Key advantages
Hydrophobic PU foam for high-flow water arrest
Hydrophilic PU gel for flexible permanent sealing
Acrylate resins for fine cracks and capillaries
Specialist injection through packers and lances

Our diagnostic process
We find the root cause before we quote.
Every repair starts with a structured site investigation — so the fix is permanent, not cosmetic.
- 01Source mapping (entry vs exit)
- 02Leak rate measurement
- 03Joint and penetration survey
- 04Crack width and movement check
Repair methods
The right technique, not a one-size repair.
02
Hydrophilic acrylic gel
Permanent flexible sealing in moving joints and around penetrations.
03
Combined sealing
PU foam for immediate stop + acrylic gel or epoxy for permanent durability.
Emergency response
Emergency call-out — UAE response within 4–8 hours for active leak events.

Frequently asked
Leak Sealing Injection — answered.
Common questions from UAE consultants, clients and contractors. Need something specific? Speak with our technical team.
Hydrophobic PU reacts with water, expands and cures to a closed-cell foam that is stable in dry and wet cycles — used for high-flow leaks. Hydrophilic resin absorbs water and stays flexible — used for fine, moving joints that remain damp.
