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.
Manufactured with premium APP resins, and incorporating distilled bitumen and the latest generation of polyolefin techno polymers
The membrane is reinforced with a non-woven continuous fiber polyester mat, in combination with a steel reinforcing mat
Stabilized with fiberglass thread to give the membrane a high longitudinal stability
The top finish is silica sand
