HEAVY PROTECTION SYSTEMS 1. Preparation of roof for paving. A 20-mm thick bed of sand will be laid on top of the waterproofing system previously applied. The sand will be covered by a 1-mm thick polyethylene sheet or by 300 g/m² bitumenised felt. The whole area will then be levelled by the application of 4-cm thick layer of concrete based on 350 kg of Portland 325 cement for cubic meter of mix. Where the floor needs to be reinforced, a bigger thickness of the levelling layer could be foresees. In all cases an opportune number of expansion joint has to be incorporated. 2. Protection layer of gravel. On the top of the membrane 200 g/m² non-woven polyester should be dry-laid down allowing for 100 mm overlaps. Finally a layer of cleaned and rounded gravel having a granule size of about 16÷32 mm should be evenly laid down. Usually gravel’s thickness of 4÷5 cm is used. 3. Floor in prefabricated paving slabs The paving slabs will be a minimum of 30-mm thick and 400 x 400-mm in size. The slabs should be laid using plastic support (like HELASTORING) which will rest directly on the waterproofing membrane. 4 th Section Production description Bitumen is supplied in a liquid phase from the refineries and is stored in heated tanks. For the preparation of the new compound it is transferred to a balance weight and then pumped into vertical mixers. Distinguished mixers are kept for SBS and for APP compound. Here, weighted polymers and inerts are added and mixed together. When the compound is homogeneous it is transferred to a holding tank and finally to the impregnation bath pipelines and impregnators baths are reserved for only one type of compund. The reinforcement comes into the melt compound and becomes impregnated. A constant thickness of compound on the bottom side is guaranteed with a special device, later on, a layer of APP compound is spread on top of the membrane, and the total thickness is then controlled with another dedicated device. The membrane is then cooled down with several water baths, during this operation different type of surface finishing could be done (flamina, sand, Texflamina, slates etc). The final part of the production line involves rolling up, cutting into the right length and packaging the membrane with proper tape. A standard roll measure is 10 by 1-m and it is packed with two coloured tapes which show identification trade name thickness and production site. Each roll is marked with adhesive ticket-control with a recorded number, which allows the quality control service to identify the production lot. All the operations are made automatically and the rolls so finished are sent to palletizer machine, where a shrinkable bag is put on the pallet. Page n° 21 out of 24
