Project Overview
This was a commercial roof waterproofing project for a running restaurant located in DHA Phase 2 Islamabad. The main goal was to permanently stop water seepage and protect the interior structure from rain-related damage.
Main Problems Identified:
- Active roof leakage during rain
- Multiple cracks in RCC slab
- Failed old waterproofing coating
- Water seepage in ceiling corners
- Improper roof drainage flow
Site Inspection & Technical Analysis
Before starting work, the Hazir Pakistan technical team conducted a detailed inspection of the rooftop to identify leakage sources.
Inspection included:
- Crack mapping on concrete surface
- Water ponding areas
- Drainage slope condition
- Parapet wall joint leakage points
- Previous coating failure zones
After analysis, a PU-based waterproofing system with fiber mesh reinforcement and multi-layer coating system was recommended for long-term durability.

Waterproofing System Applied
The project was completed using a high-performance PU waterproofing system suitable for commercial rooftops exposed to heat, rain, and temperature changes.
Step 1: Surface Cleaning
Roof surface was thoroughly cleaned to remove dust, loose particles, and old weak coating material.
Step 2: Crack Repair & V-Grooving
All visible cracks were opened, cleaned, and filled with high-strength crack sealing material.

Step 3: Fiber Mesh Reinforcement
Fiber mesh was applied on cracks, joints, and parapet wall corners for extra structural strength.
Step 4: Primer Application
A strong bonding primer was applied for proper adhesion between concrete and PU coating.
Step 5: First PU Waterproof Layer
First layer of PU coating was applied evenly across the roof surface.
Step 6: Second PU Waterproof Layer
Second layer was applied after curing time to form a seamless waterproof membrane.
Step 7: Protective UV Topcoat
A UV-resistant protective coating was applied for long-term weather protection.
Project Challenges
Since the project site was an active restaurant, Hazir Pakistan ensured:
- No disruption to restaurant operations
- Safe working near kitchen exhaust areas
- Fast-curing material selection for efficiency
- Clean and controlled application process
The project was completed successfully within the planned timeframe without affecting business activity.
Final Results
After completion of the waterproofing system by Hazir Pakistan, the roof is now fully protected.
Achieved Results:
- 100% elimination of roof leakage
- Strong crack sealing system
- Seamless waterproof membrane formation
- Improved roof durability
- Long-term rain resistance achieved
- Protection of interior ceilings and walls
Why PU Waterproofing Was Selected
PU waterproofing was chosen because:
