MasterShield WP 720

SBS Modified Bitumen Waterproofing Membranes

Material Description

MasterShield WP 720 are elastomeric waterproofing membranes, manufactured in an advanced continuous calendaring process by saturating and coating a synthetic carrier with a waterproofing compound made of a special grade of bitumen, modified with SBS polymers. While the SBS polymers enhance the thermal, mechanical, and aging properties of the membrane compound, the mechanical characteristics of MasterShield WP 720 are established by the non-woven continuous filament spun-bond Polyester which acts as the reinforcement that provides the membrane with its particular tensile strength, tear resistance, puncture resistance and elongation properties. The upper surfaces of MasterShield WP 720 is covered with an anti adhesive finish material, whereas the lower surface is laminated with a thermofusible polyethylene film.

Areas of Application

• MasterShield WP 720 are multi-purpose membranes for waterproofing applications subjected to different mechanical stresses, movement and significant weathering conditions, can be used as a single layer in specific applications.

• MasterShield WP 720 membranes are particularly recommended for foundations & underground structures.

Characteristics and Benefits

• Fully bonded system
