Gripset C-1P – Flexible Cementitious Membrane

Gripset C-1P is a one-component, fibre-reinforced cementitious waterproofing membrane engineered for both positive and negative pressure applications. Designed with advanced polymer technology and graded aggregates, it provides excellent crack-bridging, flexural strength, and long-term durability in continuously wet or immersed environments.

This versatile membrane can be applied by brush, roller, trowel, or spray and is suitable for use on concrete, masonry, and render. C-1P withstands hydrostatic pressure up to 5 bar positive and 1.5 bar negative, making it ideal for retaining walls, basements, tanks, and under-tile waterproofing. It complies with AS 4858 and is approved for potable water applications under AS 4020.
