Two-component hybrid aromatic polyurea resin that cures very quickly into an elastic membrane with crack-bridging capacity. This product can only be applied using two-component spraying equipment and can be combined with different geotextiles to obtain on-site, seamless liners. It can also be pigmented with aluminum particle pigments to obtain sun-reflective properties. The product is highly resistant to meteorological phenomena, especially hail, and acts as a radon gas barrier, which is naturally generated in the earth's crust.
