Excavate a hole of suitable dimensions with a hat bottom, leaving a space of at least 20/30 cm around the tank.ln the presence of heavy soil (e.g. clayey subsoil and/or groundwater) the distance must be at least 50 cm. Spread a 15/20 cm deep layer of 2/6 washed gravel on the bottom of the excavation to allow the tank to rest on a uniform and level base. Excavated material must not be used as backfill. The excavation must be a minimum of 1 m from any structures. 2. BACKFILL AND FILLING 2.1 Place the totally empty tank on a bed of 2/6 washed gravel spread at the bottom of the excavation, gradually...

UNDERGROUND INSTALLATION2.3 EXTENSION INSTALLATION If the tank is installed at a depth of 30/40 cm and the site is to remain open to pedestrian traffic, it is advisable to install the (5:5:94 KE 9x:9DS<5D directly on the inspection holes. In the case where the tank is installed deeper than that previously indicated, which constitutes an unfavourable condition and not recommended, adhere scrupulously to the instructions reported in chapter 4 "Trafficability". The technician responsible for the installation will follow the instructions reported in the two paragraphs according to the installation...

Installation in the presence of groundwater is not recommended as it represents one of the riskiest conditions for a storage tank. In this case, it is advisable to obtain a geotechnical report from a specialist. From the report, the installation technician will be able to define the expected pressure from the groundwater and design the backfill material and slab accordingly. In particular, he will design the backfill to have the necessary capacity for resisting the high lateral forces. The resistance capacity can be further increased by inserting an electro-welded wire mesh. Construct the concrete...

TRAFFIC4.1 LIGHT TRAFFIC - CLASS B125-EN124/95 - MAX 12.5 TONS To render the site suitable for the transit of light vehicles, a self-supporting reinforced concrete slab, designed in relation to the load, must be constructed. The perimeter of the slab must be larger than the excavation to prevent the weight of the slab from bearing on the tank itself. It is also recommended that you construct a concrete slab (for example 15/20 cm in height" at the bottom of the excavation, over which a 10 cm thick layer of 2/6 washed gravel must be spread to fill in the voids between the corrugations in the base...
