If not correctly observed, any right to claim on the guarantee may be refused. For all additional GARANTIA articles purchased there are separate installation instructions enclosed in the transportation packing. Any missing instructions must be requested directly from us. A complete check of the tank for possible damage must be carried out before the installation in the excavation begins. The installation must be carried out by a professional firm.

Furthermore, when carrying out assembly and installation work, inspection, maintenance and repairs, all work regulations and norms must be followed. The GRAF company offers an extensive range of accessories that are all compatible with one another and may be used to construct a complete system. The use of other manufacturers accessories can impair the function of the system and liability for any resulting damages will no longer be covered under the guarantee.

To connect the inlet and venting piping there are prepared positions for the openings to be cut out of the plastic ribbing. The pipes must extend at least 20 cm into the module. Should an installation over a wider area be proposed, then there must also be an appropriately greater number of inlet pipes to ensure an even distribution of the water. 4.2 Installation of the drainage blocks The geo-textile must be laid out in the excavation that has an even bottom surface with an overlap of not less than 30-50 cm. The modules are then positioned on the geo-textile (only laying down, never in the standing position) and all fastened together with the fastening pieces. For fastening lengthwise as well as widthwise, at least two fastening pins are required in each direction. When the system is to be built in several levels, then the individual layers must be arranged both lengthwise and crosswise (widthwise) to one another to ensure a stable interconnection. Before filling, the module must be completely wrapped in the Geo-textile and special attention must be paid to ensure that all the ends and edges of each fleece roll overlap by at least 30-50 cm. To conclude the installation, the excavation is evenly backfilled and compacted. The terrain of the ground surface and substructure should be the expected load to be prepared. If it is intended that grass should be sown over the GRAF drainage blocks, then a heavy duty plastic sheeting should first be laid over the drainage blocks and this then covered by an approximately 10 cm thick layer of clay otherwise the grass will dry out too quickly.
