PRODUCT TECHNICAL DATA SHEET THE PRODUCT RADONSTOP P is an plastomeric type membrane, obtained from distilled bitumen modified with elastoplastomeric (APP). RADONSTOP P is reinforced with “non-woven” spunbond polyester. 
 The product is a good barrier at RADON. The characteristics have been sessed by the CSI Institute with certificate n. 151/LFC/MAT/00. USES RADONSTOP P is used together in the double layer system. Designed for installation as radon gas protection and waterproofing for basements and foundations. Ideal as radon barrier for the indoor premises (basement, cellar and inner block walls and floor). We recommend the use of RADONSTOP P together with RADONSTOP membranes as double layer in the renovation of old buildings. FINISHES Upper surface RADONSTOP P membrane is available with sand, to ensure that the rolls unwind correctly. Lower surface RADONSTOP P has a polyethylene heat sensitive torch off film which prevents the rolls sticking together, allowing the gases to escape, besides giving a nice looking finish to the rolls. PACKAGING The rolls are generally 1 m wide and 10 m long. The upper tape indicates the product brand name and the lower tape the weight or thickness of the product. The rolls are supplied on wooden pallets and are held in place by a protective heat shrunk polythene covering. Each pallet has two Quality Control Tickets which enable an easy identification of the product and the retrieval of its technical characteristics when needed. TOOL REQUIREMENTS For the correct installation of RADONSTOP P type membranes, all that is required is a propane gas roofing torch with a gas bottle, reduction valve and at least 10 m of approved type hose, a round nosed trowel or spatula, a utility knife, and a pair of gloves. INSTALLATION The surface where the membrane has to be installed must be smooth , clean , dry and treated, if required, with primer coating (for example if the material has to be fully bonded) , to enhance the adhesion of the membrane to the substrate . The membrane rolls will be unrolled and laid out on the dry primer coating, then aligned before being rolled up again. The membrane is then slowly unrolled while the lower surface is heated using the propane gas roofing torch until the polyethylene torch off heat sensitive film melts and the bituminous compound starts melting . Side laps must be at least 80 mm and head laps 150 mm. After performing the overlap, the joint (while still hot) must be pressed, using a round nosed trowel, to ensure its good seal, and to level the molten bituminous compound that seeps from a correctly executed joint. The hot surface of the membrane should not be scraped using the trowel to avoid the exposure of the reinforcement.
