WHAT WE DO BEST

APP Membrane Installation

APP (Atactic Polypropylene) membrane installation is a widely used method for waterproofing roofs, foundations, and other structures. It provides a highly durable and flexible waterproofing solution, offering protection against water ingress and environmental factors.

What is APP Membrane?

APP membrane is a modified bitumen product that uses plastic modifiers to enhance flexibility, durability, and UV resistance. It is typically supplied in rolls and is installed using heat fusion methods. This type of membrane is ideal for areas exposed to harsh weather conditions.

Benefits of APP Membrane

Installation Process

  1. Surface Preparation: The surface must be clean, smooth, and free of debris or cracks. Any imperfections are repaired before installation.
  2. Primer Application: A primer is applied to the surface to ensure better adhesion of the membrane.
  3. Heating the Membrane: The APP membrane is heated with a blowtorch to soften the bitumen, allowing it to adhere to the surface.
  4. Rolling the Membrane: The softened membrane is unrolled onto the surface while applying even heat to ensure proper bonding.
  5. Sealing the Joints: Overlapping sections of the membrane are sealed using heat welding to ensure a watertight seal.
