In the case of moisture problems in basement rooms, the proposed system consists of six components. First, completely remove the affected surface from the floor level, taking care to reach the brick or stone and removing the baseboards beforehand. At this point, begin applying the first component of the system, Diathonite Regularization, a pre-mixed mortar based on natural hydraulic lime and selected mineral aggregates with the appropriate particle size distribution. Its function as an anti-saline barrier assists in addressing moisture-related issues. Its composition and breathable characteristics ensure excellent water vapor permeability, allowing proper masonry transpiration and blocking the diffusion of salt crystals. To counteract moisture with counterthrust, the system then involves using WATstop, a three-component epoxy-cementitious waterproofing compound, an excellent solution for addressing negative or positive rising dampness. Before WATstop fully dries, apply the dehumidifying plaster Diathonite Deumix⁺ by hand or with a plastering machine on the surface up to 50 cm above the ground line. This mortar is then smoothed out using Argatherm, a finishing lightweight product formulated with very fine expanded mineral fillers. The system is finally finished with C.W.C. Stop Condense, a product designed to eliminate any type of condensation and mould, after priming with D20, a water-based acrylic resin bonding agent.
