Shelterbit Vented Base Sheet)

ARDEX WPM 115 (Shelterbit Vented Base Sheet) is an A.P.P (Atactic Polypropylene Plastomeric) type modified bitumen membrane vented base sheet consisting of a specially formulated bituminous compound of distilled asphalt modified with selected high grade visco-elastic polymers.

A protective heat sensitive polythene film covers both surfaces of the vented Base Sheet.

FEATURES AND BENEFITS

ARDEX WPM 115:

• Is a specially designed perforated base-sheet for use in a multi-layer waterproofing system.
• Virtually eliminates bubbles and blisters forming underneath the waterproofing layer.
• Allows vapour permeating through the deck to diffuse underneath the waterproofing where ideally aerators will be installed to allow the vapour to escape to atmosphere.
• Eliminates the creation of stresses in the waterproofing layers thus greatly reducing failures in the waterproofing caused by deck movements.
• Is the ideal solution for controlled partially attached first layer in a multi-layer system.
