NCL PU GROUT is a low viscosity hydrophobic hydroactive two-part rigid Polyurethane injection resin designed to seal water infiltration through concrete deficiencies such as cracks, cold joint, segregation, porosity and other imperfections especially in underground infrastructure.

The curing profile of NCL PU GROUT is controllable by modifying the Hardener proportion to suit different site condition. Thus, NCL PU GROUT is suitable for sealing all type of concrete structure with various severity of leakages from minor moisture intrusion to gushing water.

Once cured, NCL PU GROUT forms a permanent watertight seal and excellent barrier against moisture and water seepage caused by hydrostatic pressure.

NCL PU GROUT is a low viscosity Two-part Polyurethane Injection Resin which consists of Part A – Resin/Base and Part B – Hardener. Part A and Part B are pre-mixed before application.

NCL PU GROUT can be injected using single-line high-pressure injection machine e.g. NCL SWM1000, NCL SWM1100, NCL DHP-M1000 or NCL DHP-M2000. The resin and hardener shall be mixed homogeneously before use. Refer to Method Statement for complete guide.


The hydrophobic injection resin first displace water then react, expand and foams to dense closed-cell rigid watertight seal in concrete structure.

It is recommended to keep container tightly closed in a cool (20 - 25°C), dry and well-ventilated place. Partly used drums/pails should be properly sealed to prevent ingress of moisture. To increase the material life expectancy, partially used drum/pail can be filled with nitrogen gas and sealed tightly to prevent contamination. When the material is stored properly, the shelf life is approximately twelve (12) months from the production date.

Waste disposal should be in accordance with all applicable local and national regulations. Kindly check with the local authorities on proper disposal method. Empty drums/pails should be punctured to clear the content. Care must be taken to prevent environmental contamination from the use of this material.

  • Ingestion: Do not induce vomiting. Treat symptomatically and get medical attention immediately.
  • Inhalation: Remove from exposure. If there is any difficulty in breathing, get medical attention immediately.
  • Skin Contact: Remove contaminated clothing. Immediately flush affected area thoroughly with mild soap and water.
  • Eye Contact: Immediately flood eyes with plenty of water for a minimum of 15 minutes holding the eyes open.
