The protection products install an invisible barrier that prevents the degradation of bases (roofs, walls, facades, paving). They protect against bad weather, (rain, ice, etc.), whilst reducing and limiting the incrustation of stains, (greasy substances and micro-organisms), that occur over time. The application of a waterproofing agent product allows the strengthening of porous materials and increases their lifespan without changing the appearance nor the structure of the materials. These products are biodegradable, without solvent or silicone and let the materials breathe.
