HT Green™ is a 300micron extra thick, super hi-strength, concrete underlay rated “HEAVY DUTY”. This ‘see through’, tear resistant polyethylene film has been extruded using special resins to promote tough properties within the membrane. Designed for floors that require a higher impact resistance than standard polyethylene films. HT Green is used as a concrete underlay and a moisture vapour barrier in areas of extreme conditions where protection and strength are required. HT GREEN is designed for floors that would potentially be down for longer periods than what a normal floor would take prior to concreting to allow more durability for extra foot traffic and is an added extra precaution for the disconcerting architect or builder.


HT Green Super Hi-Strength Concrete Underlay to meet the performance requirements of NZBC Clauses B2, Durability B2.3.1[a] 50 years and B2.3.1(b) 15 years, E2 External Moisture.
