Waterproofing and uncoupling membrane with a studded structure formed by an internal waterproof layer coated on both sides with non-woven fabric, which guarantees perfect adhesion and stability of the cementitious adhesive, ensuring maximum cohesion between the layer and the substrate and excellent stability of the overlying flooring. Decoupling layer for securing flooring against dimensionally unstable, highly stressed, cracked, not perfectly cured subfloors. It allows decoupling the screed joints from the expansion joints of the flooring, ensuring continuous tiling free from cuts necessary to respect the underlying screed fractionation joints. Advanced lamination technology that guarantees secure and durable anchoring of the flooring to the underlying substrate. Product for professional use.
