The Armor Membrane


The Armor membrane is the last line of protection in the Dri-Shield System of protection for expansion joints. The steel mesh has been added to strengthen the membrane against the mechanical shock and compression of applied heavy loads. Centered on the expansion joint gap, it provides the strength and stability to perform effectively.


The Armor membrane is a 4mm prefabricated polyester reinforced Atactic Polypropylene (APP) modified bitumen product specially designed for heat-welded applications.

Premium Resins

Manufactured with premium APP resins, and incorporating distilled bitumen and the latest generation of polyolefin techno polymers

Reinforced Fiber

The membrane is reinforced with a non-woven continuous fiber polyester mat, in combination with a steel reinforcing mat

Stabilized Fiberglass

Stabilized with fiberglass thread to give the membrane a high longitudinal stability

Silica Finish

The top finish is silica sand


Armor Membrane is a perfect waterproofing membrane due to the following key features.


Armor Membrane is puncture and tear resistant which ensures its durability when used in waterproofing systems.


The ability to be quite flexible allows the Armor Membrane to be installed anywhere. This is why it is used extensively for curb line flashing.

Elongation Properties

Armor Membrane has superior elongation properties.

Tensile Strength

High tensile strength enables the Armor Membrane to endure heavy pressures and harsh temperature conditions ensuring reliability and efficient waterproofing results.
