Description:

Ultra-fluid, one-component polyurethane injection resin with adjustable reaction times, for waterproofing structures, grounds and rocks subject to intense water seepage.

Technical Charateristics:

Resfoam 1K-M is a one-component polyurethane resin, free of halogens, made up of a mix of isocyanates, special admixtures and an accelerator prepared according to a formula developed in MAPEI researchlaboratories.
In order to achieve different reaction times, before using, Resfoam 1K-M must be mixed with Resfoam 1K-M AKS (accelerator) in a dosage from 1 to 10% by weight of resin, according to the needs on the jobsite.
After mixing with the accelerator and in the absence of damp conditions, Resfoam 1K-M has a pot life of
approximately one hour. During its pot life, Resfoam 1K-M must be injected through special packers into the structure that needs to be waterproofed by a piston pump or a membrane for one-component products. When the resin comes in contact with water, it forms a semi-rigid waterproof polyurethane foam. Thanks to its high fluidity, Resfoam 1K-M penetrates into about a hundred microns wide cracks and can seal them even if they are subject to water seepage. Once set, after 40-80 seconds depending on the temperature and the amount of added accelerator, Resfoam 1K-M ensures
