Excellent Waterproofing

Forms a durable barrier that prevents water from penetrating the concrete surface

Breathable

Allows trapped moisture vapour to escape while preventing liquid water from entering.

Good Flexibility

Accommodates minor substrate movement and helps bridge small cracks without compromising the waterproofing layer. Tested to ASTM D412 for tensile strength and elongation.

Good Adhesion

Bonds strongly to concrete and cementitious surfaces, including damp substrates and green concrete. Pull-off adhesion strength tested to ASTM D7234.

Non-toxic

Formulated without harmful substances and certified to MS 1583: Part 1: 2003 by SIRIM QAS for suitability of use in contact with water intended for human consumption.

Excellent Chemical Resistance and Acid Resistance

Resists deterioration caused by soil chemicals, chlorides, sulphates, dilute acids and alkalis.

Anti-Carbonation and Anti-Chloride Ion Protection

Helps reduce carbon dioxide and chloride ion penetration, helping to increase the structure’s lifespan, protect concrete alkalinity and reduce the risk of steel reinforcement corrosion.

Green-Label Certified

Tested under SGLS Category 032 by SETSCO, supporting its suitability as a more environmentally responsible building material.

Waterproofing (First Coat)

NippoCEM FLEX 1K 902

A fibre-reinforced cementitious waterproofing element helps add thickness to reinforced concrete (RC) substrate for resistance against chemicals, carbonation, and chloride ion penetration. The one-component element makes this product simple enough to be mixed accurately until homogeneous consistency is achieved

Waterproofing (Second Coat)

NippoCEM FLEX 1K 902

Apply another coat of fibre-reinforced cementitious waterproofing in perpendicular motion to help add thickness to reinforced concrete (RC) substrate for resistance against chemicals, carbonation, and chloride ion penetration. The one-component element makes this product simple enough to be mixed accurately until homogeneous consistency is achieved.
