Water Impervious


Benex is classed as being Impervious to water which makes it the ideal all solution for Basements and retaining walls as it requires no further treatment and negates the need for tanking.


The resistance of buildings to moisture penetration from wind driven rain is dependent upon both the permeability of the masonry and the effectiveness of water proofing details of doors and windows. While most leakages in buildings result from the latter factors, the correct details to prevent such failures are well documented. Whatever the thickness, a single leaf masonry wall is generally not regarded as being sufficiently impervious by AS3700 without further protection.

Benex however has been independently tested by the CSIRO* using

ASTM 514-06 and found to pass this water permeability test

for more than 24 hours
