Cemix Waterproofing Admixture is a premium waterproofing additive formulated to significantly lower the permeability of concrete, mortar, plaster and screeds. When added directly to your mix, it enhances water resistance and helps protect structures from moisture damage, dampness and surface deterioration.

Perfect for both home projects and trade applications, this admixture improves durability in areas exposed to rain, ground moisture or general damp conditions. It’s an excellent support product for waterproofing systems where long-term performance is essential.

TYPICAL APPLICATION/USES:

  • Water-resistant mortar for blockwork or bricklaying

  • Exterior renders and plasters
