Fast reacting, two-component injection resin

CE marking according to EN 1504-5

Product description

WILLPUR® WS- F  is a fast-setting 2-component injection resin based on polyurethane, free of CFCs and halogens. It is used for sealing and consolidating in dry and heavily water-bearing areas. Without contact with water, the product hardens very quickly to form a high-strength, non-foamed polyurethane resin; on contact with water, a rapid reaction takes place and the product hardens to form a compact, solid foam.

Product details

  • is used for the permanent consolidation of dry and water-bearing rock
  • reliably seals pressurized water inflows from rock, soil or structures
  • is used to consolidate coal and secondary rock in mining
  • closes cracks in the rock during tunnel driving and prevents water flow along the tunnel axis
  • permanently seals cracks in concrete and masonry such as in tunnels, canals, shafts, locks, underwater concrete floors and excavation pit enclosures
  • is used for force-fit injection in concrete and masonry
