Superfluid single component polyurethane injection resin for waterproofing concrete or masonry structures, grounds, and rocks subject to also intense water percolation with variable adjustable setting times.

Resfoam 1 KM is a single component polyurethane resin free of halogens that is able to react in the presence of water by forming a foam.

Resfoam 1 KM must be mixed with 10-20% Resfoam 1 KM accelerator.

Thanks to its high fluidity, Resfoam 1 KM penetrates several hundred micron thick cracks and can seal them even if they are subject to water infiltrations. After its reaction, which occurs after 40-80 seconds depending on the temperature and the amount of added accelerator, the Resfoam 1 KM foam becomes semi-rigid and watertight.

Where to use:

  • Waterproofing concrete structures and cracked masonry subject to water seepage, also under pressure.

  • Waterproofing rocks subject to water seepage.

  • Waterproofing permeable grounds saturated with water.


Resfoam 1K-M (resin): 20 kg plastic drums.

Resfoam 1K-M AKS (accelerator): 1 kg plastic drums
