Foil Aluminium Membrane Sheet | Premium Roof & Wall Waterproofing in Lahore

Introduction: The Importance of Waterproofing

Waterproofing is a critical aspect of construction in Lahore and across Pakistan. High temperatures, heavy rainfall, and humidity can severely damage roofs and walls if proper protection is not applied. Water penetration leads to:

Structural cracks
Mold and mildew formation
Corrosion of reinforced concrete
Increased maintenance costs

A high-quality waterproofing solution is necessary to prevent these issues. Foil Aluminium Membrane Sheets are among the most effective materials for long-lasting waterproofing and heat insulation, protecting roofs, walls, and other structures from environmental damage.

Prevents punctures and wear from foot traffic or heavy equipment

Troubleshooting Common Issues

Even with high-quality sheets, certain issues may arise. Here’s how to resolve them:

Air Bubbles or Wrinkles
- Cause: Improper torch application or rapid rolling
- Solution: Reheat membrane and press firmly; ensure overlaps are properly sealed
Partial Adhesion
- Cause: Surface not cleaned or damp during installation
- Solution: Remove loose areas, clean thoroughly, and reapply primer + membrane
Tearing or Puncture
- Cause: Sharp objects, heavy loads, or foot traffic
- Solution: Patch with a new sheet, seal edges with tape or mastic
Heat Reflection Inefficiency
- Cause: Dust accumulation or oxidation of foil layer
- Solution: Clean regularly to maintain reflective properties
