Any damage identified during normal inspections should be repaired or replaced as appropriate. Specification Clauses Where so designated on the drawing, the surfaces shall be covered with a torch applied, polyester reinforced, polymer modified bituminous waterproofing membrane. The membrane shall be reinforced with non-woven polyester composite fabric and be based on distilled bitumen and polymers. Such a product is Modo/P as supplied by Parchem. Areas shall be prepared and the membrane applied in accordance with the current Modo/P technical data sheet, all materials used in conjunction with the Modo/P membrane must be approved by Parchem Construction Products. Application of the membrane should be carried out by a competent applicator, well trained in the application of modified bitumen torch applied membrane systems. For further detailed specification information refer to the appropriate Waterproofing Specification available from your local Parchem sales office. Application instructions Surface preparation All surfaces receiving the Modo/P membrane must be firm, dry, and free from contaminants and loose material. It must also be even and smooth, without any elements that could damage the membrane. Rough concrete must be “faired up” before commencing application. Contact your local Parchem office for suitable fairing products from our extensive range. Priming Index Bitumen Primer should be applied to all the prepared surfaces prior to the application of the membrane and allowed to dry. The primer will take at least one hour to dry at temperatures 25°C and above. At lower temperatures allow additional drying time. Index Bitumen Primer should be applied at the rate of approximately 0.13 litres per square metre to the surface to which Modo/P will be applied. The coverage rate for the primer will vary depending on the porosity of the surface being treated. Primer may be applied by brush, roller or spray equipment, coverage must be uniform. Primed areas must be covered with the membrane on the same day. Application Planning the installation of the membrane is important to ensure joints occur in suitable locations. Modo/P membrane must be laid to allow side laps of 10cm and end laps of 15cm. If the membrane is to be spot bonded, full bonding must occur for 1m each side of the end laps. Application of the membrane is by torch bonding using a suitable gas torch. The membrane is applied with the surface protected by the Flamina facing down towards the substrate, during the application of the gas flame the Flamina will melt away. Beginning at the lowest point of the deck area and working in the direction of the slope towards the highest point. The first roll of membrane is unrolled completely and aligned, remaining rolls should be unrolled approx. halfway in order to properly align the 10cm side lap and ensure the required 15cm end lap is maintained. Starting at the low point in the deck apply heat by the gas torch to the outer surface of the rolled portion of membrane while un-rolling, move the flame from side to side while unrolling the membrane by slightly pressing it onto the underlying surface. Avoid shifting the roll while unrolling. Follow the edge of the deck or the lap line. In order to have a smooth and even seal at the joint, apply the flame to the bleed out and the trowel simultaneously and spread the melted compound evenly to seal the joint. Proceed torching the remaining membrane as described above, working your way to the highest point on the deck always maintaining the 10cm side lap and 15cm end lap. Index® Modo/P
