A two-component, solvent-free, polyurethane injection resin that reacts to form a foam upon contact with water, expanding its volume, causing a strong seal.

Features

• the product reacts with water
• it is not a hydrophilic, but a hydrophobic type of resin, therefore the resulting foam does not absorb water, is not affected by the drying of water, does not shrink or swell
• only requires the use of one-component injection equipment; reacts with the outflowing water or the moisture present in the ground
• low viscosity, even during injection procedure, which ensures good and deep penetration
• the product does not shrink
• the stability of the chemical structure of the foam ensures high durability, high mechanical strength, and the ability to resist high water pressures
• eco-friendly
• the ability to regulate the gelation time by adding the appropriate amount of Maxurethane Injection CAT catalyst (not included in the kit)
• excellent performance; water does not dissolve the agent
• high degree of swelling, up to 15 times
• the product can be used both for cutting off the flow of water and for strengthening the soil

Application

Cutting off the water flow in:

• damaged, cracked or porous concrete
• structural and expansion joints in concrete
• brick structures
• sewage pipes, manholes, tunnels, dams
• sewage tanks and drinking water tanks
• filling large cavities and cracks in stone and concrete structures
• soil strengthening
