Aquacrete are proud to launch our latest range of Aussie made products, a waterproof membrane called Flexi-Liner™

Flexi-Liner™ is a unique product range and the class III single component cementitious is the only type of its kind in the world, exceeding 650% elongation after 21 days, just mixed with water.

All Flexi-Liner™ cementitious membrane products just mix with water, are non-toxic, earth-conscious, and LOW VOC <1mg per litre of product, the lowest possible result.  We approached the waterproof membrane market with the view that if we couldn’t do it better, then we wouldn’t do it at all.

A major factor was identifying how unique we were and how we could contribute to benefit an alarming issue, that for 1% of the cost to build the project, failures of the waterproof membrane contributed to 80% of the cost of remedial works.

You will find Flexi-Liner™ to be a competitive product and it will do what we says it will do provided the recommended installation methods and instructions are followed.

Our products are rigorously tested and approved through recognized accredited testing facilities to comply with local and international standards.

Flexi-Liner™ products can be applied by trowel, brush, roller, or sprayed depending on the application, however, it is important that correct water is added and WFT, (Wet Film Thickness) is applied. Users will not need a primer or a wet surface to apply, however it can be applied to a wet surface with no pooled water.
