Ecospritz Gunite WLT is a ready-to-use, premixed, fiber-reinforced, shrinkage-compensated  mortar, whose main component is the Ecospritz special binder, based on Type IV/A – 42.5 pozzolanic cement with high resistance to sulfates. The product is not accelerated, allowing it to be finished appropriately with either a manual or power trowel since it remains trowelable for over 60 minutes. It can be applied in layers over 4 cm thick due to its thixotropic behavior. It is suitable for constructing the final structural overlays in tunnels, tanks, pipelines, underground walls and for securing unstable walls (minimum thickness 3 cm).
