COSMO INJECTION 1K is a one component polyurethane , hydrophobic resin , which reacts with water to produce a flexible grout suitable for waterproofing and sealing cracks and joints of concrete surfaces , and for effectively stopping water leaks.

Recommended for use on concrete elements subject to structural movements.

Application is by one component injection pump.


Stopping water leaks in such structures as:

  • Foundations ,
  • Below-grade structures, e.g. garages ,
  • Tunnels & underpasses ,
  • Sewage systems ,
  • Tanks ,
  • Waterways & dams.

5 lt , 20 lt ,

  • Effective sealer of cracks & voids in concrete , especially in joints.
  • Of low viscosity: Deep penetration with minimal pressure.
  • Produces a flexible & completely hydrophobic foam.
  • Easy to apply: One component with a very reasonable pot-life.
  • Highly resistant to fungi and other microorganisms.
  • Friendly to the user and the environment: Contains no solvents or propellant gasses – safe to store , transport and use.
