Two-component injection resin based on polyurethane, 100% solids, solvent-free, high efficiency and very low viscosity. Upon contact with water (5% by weight), it forms a homogeneous, closed-cell porous structure. The material that makes up this structure is characterized by excellent waterproofing properties and high elasticity.

Features

• very low viscosity (even during injection), which ensures good and deep penetration of the substrate; the system is suitable for sealing cracks due to shrinkage
• ease of use, because application requires injection equipment intended for a single-component product
• permissibility of direct contact with drinking water
• it does not need water to react, so no water injection is necessary
• very good adhesion to dry and wet surfaces, as well as flexibility
• after the end of maturation, excellent dimensional stability, because no shrinkage or swelling (bulging) occurs regardless of dry or wet conditions
• good performance, the product is not soluble in water
• good chemical resistance and long-term, great mechanical strength
• Solvent-free, environmentally friendly product
• compatible with concrete, steel and other injection resins based on polyurethane

Application

• sealing concrete and masonry structures using the previously installed Maxurethane Injection Tube system or using standard injection packers
• cutting off water, sealing and flexible filling of gaps and cracks formed on dry and wet substrates: concrete that is damaged, cracked or has holes like a sieve; - stone and brick structures; underground structures such as tunnels, cloisters, arcades, retaining walls, foundations, etc .; water supply network: dams, reservoirs, canals, basins, etc .; sewage system: sewers, manholes, waste water tanks, etc.
• clogging the leakage of running water, flowing under low or medium pressure
• controlling the capillary rise of moisture in masonry
