Bituminous Membranes

Proven performance for heavy-duty waterproofing.

Overview

Bituminous membranes remain the gold standard for robust waterproofing in both hot and cold climates. Our APP (Atactic Polypropylene) and SBS (Styrene-Butadiene-Styrene) modified sheets are engineered to provide maximum resistance to aging, thermal shock, and mechanical stress.

Key Features

Superior Aging Resistance

High-quality polymer modifiers ensure the membrane retains flexibility over its service life.

Excellent Heat Stability

Withstands high temperatures during application and in extreme climates.

High Tensile Strength

Heavy-duty polyester reinforcement provides resistance to puncture and tearing.

Applications

  • Multi-layer roofing systems for commercial projects
  • Tanking and foundations in high water table areas
  • Bridges and parking decks with heavy traffic
  • Lining of irrigation canals and reservoirs

Installation Guide

For torch-applied bituminous membranes, correct substrate preparation and flame application are critical for a watertight bond.

  • Substrate must be primed with Awazel D-Primer.
  • Unroll and align the membrane before torching.
  • Maintain 10cm side laps and 15cm end laps.
  • Avoid excessive torching to prevent modifier damage.
