N.1 PREPARATION OF THE SUBSTRATEN.1.1 INSTALLATION AND PREPARATION OF FLAT ROOFS Procedure Before installing a waterproofing system made from a synthetic membrane, the roof must be installed and/or checked to make sure it is suitable for use and that it has been prepared correctly. Reinforced cement and concrete-masonry flat roofs Reinforced cement and concrete-masonry flat roofs must be dimensioned to withstand the design loads and overloads, and a cement levelling layer must be applied to form a slope. To make the substrate suitable for applying the system, the following must be carried out:...

Wooden decking flat roofs Wooden decking flat roofs must be dimensioned to withstand the design loads and overloads. The wooden decking may be made from planks of deal perfectly butted together, beaded birch planks, plywood panels or oriented strand board (OSB). To fix the planks and/or panels for the decking in place to the load-bearing structure and prevent them warping, use special wood screws or deformed shank nails. Fixing the planks or panels in place with traditional nails is not recommended. To make the substrate suitable for applying the waterproofing system, the following must be carried...

WATERPROOFING SYSTEMS FOR FLAT ROOFS BALLASTED WITH GRAVEL FLAT ROOFS BALLASTED WITH GRAVEL - COLD-ROOF SYSTEM Procedure Preparation of the substrate Installation and/or checking of reinforced concrete or concrete-masonry substrates with a suitable cement levelling layer to form a slope (see section N.1.1). When handed over, substrates must be smooth, clean and dry and all corners and edges must be smooth. Application of the compensation and levelling layer Loose-laid Polydren 500 PP 100% polypropylene non-woven, needle-punched fabric with a weight of 500 g/m², with overlaps approximately 10...

Vertical turn-ups PVC-P membranes Vertical turn-ups for waterproof membranes around the edges of roofs, wall fillets, mass fillets, skylights, etc. using: - Mapeplan B 15 1.5 mm-thick, UV-resistant and weather-resistant membrane in PVC-P reinforced with dimensionally-stable glass mat (see section N.2.1.6) for 1.5 mm thick waterproof membranes; - Mapeplan B 18 1.8 mm-thick, UV-resistant and weather-resistant membrane in PVC-P reinforced with dimensionally-stable glass mat (see section N.2.1.7) for 1.8 mm thick waterproof membranes. Fully-bond the turn-ups to the substrate using Mapeplan ADS 200,...

Application of the protection layer Loose-laid Polydren 500 PP protection layer in 100% polypropylene non-woven, needle-punched fabric with a weight of 500 g/m², with overlaps approximately 10 cm wide between adjacent sheets (see section N.2.1.11). Application of the ballast layer Application of a layer of ballast to counteract the suction effect of wind, made from washed, round gravel with a grain size of 16 to 32 mm (see section N.2.1.12). Apply an even layer at least 50 mm thick. Apply the layer of ballast carefully to avoid damaging the underlying waterproofing layer.

N.2 WATERPROOFING SYSTEMS FOR FLAT ROOFS BALLASTED WITH GRAVEL N.2.1.1 Application of non-woven fabric to form the compensation and levelling layer Supply and application of a compensation and levelling layer made from 100% polypropylene non-woven, needle-punched fabric with a weight of 500 g/m2 (such as Polydren 500 PP produced by POLYGLASS S.p.A.). The product must have the following characteristics: average tensile strength according to EN ISO 10319: 12 (-13%) kN/m average elongation at maximum load according to EN ISO 10319: > 50% static puncture resistance CBR according to EN ISO 12236:...
