Specification Clauses Where so designated on the drawing, surfaces shall have a self adhesive SBS modified bituminous waterproof membrane applied. The membrane shall have a total thickness 1.5 mm and incorporate a polypropylene mesh and a top layer protective film. The membrane must have a tensile strength of not less than 50 N/ mm2, and an elongation at break greater than 25%. The puncture resistance must be greater than 800 N (ASTM E154) and the adhesion to primed concrete must be greater than 4 N/ mm. The membrane must utilise a selvedge strip to ensure a bitumen to bitumen bond at the longitudinal joins. Such a product is Emer-Proof HD as supplied by Parchem. Areas shall be prepared and the membrane applied in accordance with the current Emer-Proof HD data sheet, paying attention to priming requirements. Both the manufacturer and supplier must be ISO 9001 accredited. Application Instructions Surface preparation All surfaces to which Emer-Proof HD is applied must be smooth and free from contaminates and any loose material. Rough concrete should be “faired up” before membrane application. Priming Emer-Proof Self Adhesive Primer should be applied at the rate of 6 - 8 m2 per litre to surfaces which will have Emer- Proof HD applied. The coverage rate for the primer will vary depending on the porosity of the surface being treated. Allow the primer to dry for a minimum of 2 hours and a maximum of 8 hours, at temperatures of 25°C and above, or until touch dry. Longer drying times will be required at lower temperatures. Priming should only be carried out on surfaces which will be covered with Emer-Proof HD on the same day. Application Planning the installation of the membrane is important to ensure joins occur in suitable locations and not at corners and penetrations. Longitudinal overlaps should be 50 - 60 mm and transverse laps 70 - 80 mm. Application of the membrane should always start from the lowest point on a surface to ensure laps are self-flashing. Apply suitable lengths of Emer-Proof HD membrane by first carefully aligning the roll and applying an initial 300 mm of material, then pull the siliconised release paper and press the membrane on to the prepared surface. Take care not to incorporate air bubbles under the membrane or wrinkles in the membrane. 473 Emer-Proof® HD Woven polypropylene surfaced, bituminous self adhesive membrane Uses Emer-Proof HD is used to waterproof bridge decks, ramps, car parks, and road pavements where the membrane will be overlaid with hot asphalt. Advantages „ Self adhesive - allows installation without the use of heating torches while providing a fully bonded membrane system „ Suitable for the application of hot asphalt up to 165°C directly over the membrane „ Uniform thickness - eliminates any likelihood of thin application commonly found with liquid applied membranes „ Contains a polypropylene mesh for extra strength, puncture resistance and dimensional stability „ Selvedge strip provides bitumen to bitumen seal at longitudinal joins ensuring watertight seal Description Emer-Proof HD is a self adhesive bituminous membrane incorporating a polypropylene mesh for added strength and heat stability. The bitumen compounds used to manufacture the product are modified with SBS to promote maximum elasticity. The top face of the membrane is treated with a protective film.
