PRODESO MEMBRANE SYSTEM is an uncoupling and waterproofing system for difficult floors, terraces, balconies and horizontal surfaces of all dimensions without movement or expansion joints in the screed. The membranes are placed over the floor before the ceramic tile or natural stone surface is laid. There are many good reasons for using this type of membrane, which Progress Profiles has designed and made to guarantee maximum flexibility, protection and safety inside and outside the home. First of all, it is quick to lay and drastically reduces work times. The floor surface can be installed as soon as the membrane is in place. Next, it is versatile and can be used on all types of floor, indoors and out, irrespective of dimensions. Finally, it is safe under all conditions and in all weathers, and facilitates the laying of all kinds of floor. It even waterproofs the substrate in the case of overlaying on cracked or imperfectly cured floors with a risk of vapour stress.
