Rainwater tank ULCS

water storagein-groundprefab

This piece is manufactured to measure in a single piece by hot vulcanisation in our factories, whilst having the advantage of regular quality control. This a cellular structure storage system, covered and sealed by the EPDM geomembrane, which is useful for storing rainwater under roads, car parks, green spaces, for use as a basin in an urban environment or as an underground fire storage tank. The EPDM geomembrane makes it possible to ensure that ULCS (Ultra-Light Cellular Structures) underground tanks are watertight. It is compatible with all types of ULCS. The ready-to-install EPDM 3D sealing geomembrane is manufactured to your measurements in the factory A turnkey solution in a single piece of up to 500 m² corresponding to the precise dimensions and shapes of each project The piece is manufactured in the factory in a clean environment and makes the achievement of a high quality level possible très élevé The EPDM geomembrane is assembled in the factory by hot vulcanisation providing extreme resistance Maximum solidity of the welds due to the hot vulcanisation Excellent mechanical resistance (traction, elasticity, static puncture) Waterproofing piece guaranteed for 10 years Service life of more than 50 years for the EPDM material Perfect resistance to UV and extreme temperatures (- 40°C to + 120°C) An economical solution that is more environmentally friendly Greatly reduced implementation costs as a result of the prefabrication Significantly lower labour costs No trimming or material loss Maximum longevity of the waterproofing Synthetic membrane that is more ecological than bitumen paints
