Injection Waterproofing
Cracks, Seepage, or Damp Walls? We’ve Got the Fix.
Our team delivers the best injection waterproofing in UAE using advanced PU systems for fast, durable, and hassle-free results.
What is Injection waterproofing?
Injection waterproofing is an advanced way of fixing leaks from the inside. Instead of coating the surface, we drill small holes and inject PU resin directly into cracks or joints. The resin reacts and forms a flexible seal that water can’t get through.
That’s why many clients trust us for the best injection waterproofing in UAE. We’ve used this system in basements, tanks, foundations, and other structures where traditional waterproofing just doesn’t work.
It’s especially useful because it tackles the actual weak spot in the concrete. No need to rip out tiles or concrete layers. Our PU injection waterproofing locks the leak right where it starts, giving long-term protection. With skilled installers and durable materials, Prompt Insulation makes sure the fix lasts, saving clients from repeated repairs.
Why Choose Injection Waterproofing?
Anyway, why should choose injection waterproofing instead of surface fixes? Because it goes right to the root of the problem, inside the crack or joint.
- Direct sealing: PU resin expands inside cracks, blocking leaks from the source.
- No demolition: Fixes leaks without breaking floors, walls, or tiles.
- Strong and flexible: Resin adapts to slight shifts in the structure, preventing future seepage.
- Works under pressure: Handles groundwater and heavy water flow in basements, pits, and tanks.
- Long-term savings: One durable fix saves you from repeated repairs.
Prompt Insulation has been trusted as a reliable Injection waterproofing Contractor in UAE, handling everything from small leaks to large-scale water ingress in industrial, residential, and infrastructure projects. We use high-grade PU materials and trained technicians to deliver results that stand the test of time.
Signs You Need Injection Waterproofing
Sometimes water problems creep up quietly, and before you know it, they’ve weakened your structure. Look out for these signs:
- Stubborn damp spots that keep reappearing even after repainting.
- Cracks are leaking water during or after rain.
- Salt deposits (that chalky white dust) on walls or concrete.
- Rust streaks are showing up near beams or rebars.
- Mold growth in corners, despite regular cleaning.
- Water seepage in basements is strong enough to leave puddles.
- Unexplained humidity that makes spaces feel clammy.
These aren’t just cosmetic issues; they’re early warnings of structural water damage. Injection waterproofing is one of the few methods that actually seals leaks at their root.

Injection Waterproofing Process
Here’s how the PU injection waterproofing process usually works, step by step:
Inspect the site

Width, depth, and direction are measured to choose the right injection approach.
Select material

Lastly, we check and test everything in front of you to show no signs of remaining seepage.
We work fast, non-invasively, and in compliance with safety standards, and therefore, you get a lasting fix without major disruption.
Case Study
Injection Waterproofing – Building G+5P+25 Floors Tower in Sharjah
Client Concern:
ABC reported ongoing seepage in the basement parking that damaged stored goods and raised safety worries for drivers and equipment.
Inspection Findings:
- Multiple hairline cracks and voids in joints, allowing steady water ingress.
- Localised damp stains and early signs of efflorescence near columns.
Challenges:
The parking area was in constant use; the client required a solution that avoided long shutdowns and protected vehicles and inventory during works.
Our Solution:
We proposed targeted injection waterproofing to seal the leaks from within, scheduled in phases to keep most of the parking operational and allow clients continued access.
Testing & Results
After injections, follow-up inspections and moisture monitoring showed the leaks sealed and no further water tracking. Vehicle owners reported no disruption to daily parking.
Outcome
ABC expressed relief and satisfaction at the quick turnaround and discreet work. Damage claims stopped, and maintenance costs fell.
