Single Component Semi-Rigid Polyurethane Foam

Information

grouting chemical for concrete DHP-4000 is Hydrophobic Type and 2 component type quick setting Foam. It is specially manufactured for crack leakage and where water pressure is severe. Due to field conditions, you can control the reaction speed by using catalyst. It foams in 15 seconds at minimum. Therefore, it is applied where it requires quick setting such place like civil engineering field and underground structures. Since it is hydrophile property, it even reacts with small amount water. And the foam that the reacting is finished will not be influenced by water and moisture Hydro

Feature

  • Hydro reacted waterstop Foam is quick setting type therefore it is very easy to remove.
  • Reacting speed can be control by using catalyst according field condition.
  • Since it is hydrophile property, it reacts with small amount of water and forms hydro discharged and watertight foam. And waterstops minute crack thoroughly.
  • This is hydrophobic property type product. And after it finishes foaming, water and moisture will not penetrate into it. No contraction phenomenon.

Purpose

  • grouting chemical for concrete Waterstops for crack leakage spot and joint section of all the concrete structure that accompanies any movements.

grouting chemical for concrete Use for the cracks water stop of concrete structures and waterstop 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 cracked leakage section of structure that has vibration.
  • Waterstops for leakage of concrete joint section.
  • Waterstops for leakage section where humidity and dryness is mixed up together.
  • Waterstops for severe leakage section of concrete structure.
