WPA 100

Cementitious Waterproofing Membrane


WPA 100 is a single component, fibre reinforced, rapid
drying, cementitious waterproofing membrane. It is based on
special cements, modified with polymers, selected graded
aggregates and special waterproofing additives to produce a
flexible waterproofing compound. WPA 100 is suitable for both positive and negative side waterproofing applications and is capable of withstanding significant strain.

WPA 100 has excellent adhesion to concrete, cement render
and most common Fibre Cement sheeting types. WPA 100
is to be used in conjunction with WPA Elastoband SG or
WPA Butyl Tape for maximum performance and ease of
