Elasto-plastomeric prefabricated waterproofing membrane whose compound is composed of distilled bitumen, plastomers, elastomers & polyolefin’s (APAO) obtained from metallocene catalysis polymerization, with molecular weight and selected tacticity. The membrane is reinforced with a woven non woven single strand composite spunbond polyester fabric, offering very high mechanical characteristics and excellent dimensional stability. The use of these recycled and regenerated raw materials and the special processes allow the realization of light waterproofing masses, with an excellent thickness / weight ratio (in the P 4 mm version the weight of the roll is about 40 kg). Probatec Pro, on the upper face, has a woven non woven polypropylene finish which improves the walkability and allows for immediate coating. The lower face of the membrane is finished with a PE film with striped embossing.The latter has the function of optimizing and maximizing adhesion of the membrane to the laying surface during hot application: respect at a traditional embossing, the surface is more uniform. The thousand lines per square meter operate a uniform marking and close-up of the PE film thus ensuring a homogeneous opening in the phase of application, obtaining the maximum adhesion to the application plan. Striped embossing facilitates the operator during the flaming because it requires less flame intensity and therefore less absorption of heat from the product itself, eliminating the problems of “Footprints” that occur on the upper face of the both smooth and slated products.
