Crack Injection Repair in Dubai & Across the UAE
Crack injection repair is a specialized waterproofing technique used to seal active or dormant cracks in concrete structures. Whether it’s a basement wall, water tank, or roof slab, timely injection prevents water seepage, restores structural integrity, and protects your property from long-term damage.
At Salman Syed Technical Services, we use polyurethane (PU) and epoxy resins to inject and seal cracks from the inside, without needing full surface demolition.
Why Crack Injection Is Essential
In the UAE, extreme temperature swings and settlement often cause cracks in concrete. Even hairline cracks can let in water, salts, or chemicals, leading to corrosion, mold, or structural failure. Crack injection repair allows us to seal the inside of the crack by injecting low-viscosity materials deep into the void, creating a watertight and lasting seal.
This method is especially useful for inaccessible or already finished areas where removal and re-waterproofing is not practical.
Best Applications for Crack Injection Repair
Basement Walls & Raft Slabs
Stops rising damp and lateral water seepage in below-grade concrete.
Roof Slabs & Beams
Used where cracks form due to thermal expansion or rebar stress.
Water Tanks & Underground Pits
Seals leaks in concrete tanks, including fire water tanks and treated water tanks.
Wet Area Walls
Cracks behind bathrooms or kitchens can be sealed without full tile removal.
Retaining Walls
Injected from the inside to block outside soil moisture pressure.
Lift Pits
Injection repair is the go-to method for sealing active leaks in lift pits without breaking the surrounding concrete, especially in operational buildings.

Frequently Asked Questions
How much does crack injection repair cost?
We charge AED 120 per injection packer. Total cost depends on the number of cracks, depth, and resin required. Site inspection is free.
Is this a permanent solution?
If the crack is non-structural and properly sealed, PU injection provides long-lasting waterproofing. For structural cracks, epoxy injection reinforces the concrete.
How long does the injection process take?
Most small-scale projects are completed in a few hours. Larger projects may take 1–2 days depending on extent.
Will there be any damage to finishes or paint?
Minimal. We drill small holes to insert packers, and patch them afterward. We avoid breaking tiles or surface finishes where possible.
Is this method suitable for water-retaining structures?
Yes. We regularly apply injection techniques for water tanks, sumps, and basement waterproofing where full membrane systems are not practical.
