Rubber-elastic three-component hydrogel



WILLGEL® PRO is a three-component methacrylate-based hydrogel that cures to a rubber-like, flexible product.
Due to the water-like viscosity of the mixed product, WILLGEL® PRO easily penetrates all types of substrates, making it perfect for sealing fine cracks and stabilizing fine soils or porous rock/concrete. The product reaction time (curing) is controllable and adjustable, depending on the injectability and nature of the soil to be consolidated (e.g. temperature, size, depth of fissures and pore volume). The equipment used for acrylic gels can be cleaned with water, no special solvents are required."
