Crack Injection & Leak Sealing in Dubai & Sharjah

PU and epoxy injection that stops water coming through cracks and joints in concrete — basements, lift pits, tanks, slabs and retaining walls sealed from inside, without breaking out the structure.

Crack Injection & Grouting

Survey first · fixed quote in 24h

  • Survey of cracks and joints, with photos
  • Drilling and injection-port installation
  • Water-reactive PU injection for active leaks

Sound familiar?

  • Water is running through a crack in the basement wall.
  • The lift pit keeps filling with water.
  • A crack in the slab leaks every time the area above is washed.
  • Previous surface repairs over the crack keep failing.
  • Cracks in the concrete have rust staining around them.

Every one of these has a lasting fix — once the source is found.

The Survey

What we check before quoting crack injection & grouting

Most failed waterproofing jobs treated the stain, not the source. These are the points we check on every survey before we recommend a system or a price.

Wet or dry crack

Actively leaking cracks get water-reactive PU foam or gel; dry structural cracks get epoxy — the wrong resin will not hold.

Crack width & depth

Width and depth determine port spacing and resin, so the injection fills the whole crack, not just the surface.

Moving joints

Construction and cold joints that move need a flexible injection, not a rigid one that will crack again.

Rebar exposure

Rust staining and spalling are checked so reinforcement can be treated as part of the repair.

The Scope

What's included

One fixed quote covers the full system for this service — preparation, membrane, details and testing — with no line-item creep once work begins.

  • Survey of cracks and joints, with photos
  • Drilling and injection-port installation
  • Water-reactive PU injection for active leaks
  • Epoxy injection for dry structural cracks
  • Surface sealing and port removal
  • Follow-up check, photo record, and a return visit if it leaks
How It Works

From first photo to flood-tested

Start with photos on WhatsApp. We confirm the source, quote one fixed price and prove the finished work before handing it back.

  1. Photos on WhatsApp

    Send photos or video of the crack and the water coming through.

  2. Survey & fixed quote

    We check the crack type and length, then send one fixed quote within 24 hours.

  3. Inject

    Ports installed and the right resin injected until the crack is filled and sealed.

  4. Check & handover

    Checked under water pressure, then handed back with photos — and we come back if it leaks again.

Questions

Crack Injection & Grouting FAQs

The questions Dubai and Sharjah owners ask us most about this service.

Typical 2026 rates are AED 120–280 per linear metre for pU or epoxy injection — active leaks and structural cracks, depending on crack width, depth and access. Short runs have a minimum call-out, confirmed in the quote.

Yes — that is exactly what water-reactive PU injection is for. It expands on contact with water and seals the crack while the leak is active.

PU is flexible and water-reactive, used to stop leaks. Epoxy is rigid and very strong, used to bond dry structural cracks back together. Many jobs use both, in the right places.

Every rain makes a leak worse. Fix it properly, once.
