Product Information

DHP-2000 Rigid Polyurethane Foam
High pressure water Waterstops · Leakage Crack Waterstops
1 Component Type Polyurethane Waterstops for Filling

Product Information

DHP-2000 is a single component hydrophobic water cut-off grout and soil stabilization grout based on a MDI (methylene-dephenylisocyanate) polyurethane.
Upon contact with water DHP-2000 reacts to a foam while expanding its volume up to 30 times. The cured material is semi flexible and of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell.


 ● Contraction rate after hardening is the lowest in this industry.
 ● By using small amount of distinctive additive that is invented by our research team,
         hardened foam won't get decomposed in water.
 ● Since it forms high density Closed Cell Foam, nor water and moisture can penetrate
    into it.
 ● It is very easy to remove hardened substances of flowed Foam Waterstop out of crack     spot.
 ● Since it has low viscosity, it is easy to inject


 ● All concrete structure's cracked leakage spot with no vibration for waterstop repair.

Application Area 

Use for the cracks water stop of concrete structures and water stop treatment for joint areas,wet areas and areas of considerable leaks, and can be used in the following areas.  ● Waterstops for leaking section of basement parking lot and underground concrete             structure.
● Waterstops for crack leakage section of structure caused by vibration.
● Waterstops for leakage of concrete joint section.
● Waterstops for leakage section where humidity and dryness is mixed up together.

  1. It is specially designed to endure high pressure that is applied. Injected resin won't flow backward and this packer is also specially designed not to leak resin around stabilized and fixed packer.
  2. This is 1 component type high-pressure injection equipment that is specially manufactured to fill on a leakage and fracture spot by using polyurethane foam and epoxy injection material.
