Idrostop watertight construction joints from Mapei Australia

Hydrophilic expandable rubber section for watertight construction joints; available in two sizes, 20x10 mm and 20x15 mm, labelled Idrostop 10 and Idrostop 15. Idrostop is a soft preformed flexible strip, with an acrylic polymer base specially designed to form watertight construction joints up to a hydraulic pressure of 5 atm.

Idrostop does not contain bentonite. Due to its chemical composition Idrostop gradually expands when in permanent contact with water, creating an active barrier against pressurized water (positive and negative).Idrostop strip can be applied to concrete, metal, PVC and natural stone with Idrostop Mastic, a ready to use solvent-free single component adhesive with a base of MS polymers.
