Before

The roof surface was exposed to moisture penetration, surface cracks, and water ponding. Over time, these issues can lead to structural damage, insulation deterioration, and costly repairs. Without proper waterproofing, the building remains vulnerable to leaks and weather impact.

  • Visible surface cracks
  • Water seepage and damp patches
  • Reduced structural protection
  • Risk of long-term damage

After

After Installing

With the application of Weidun® 001 PE Smooth Bitumen Membrane, the surface is fully sealed and protected. The multi-layer membrane system ensures strong adhesion, enhanced durability, and long-lasting resistance against water penetration and harsh environmental conditions.
