GEOlight® - Water storage in underground tanks

GEOlight® is a block of cells made up of assembled thermoformed sheets. It is an ultra lightweight honeycombed modular structure with good mechanical resistance and a high void rate (95%). The GEOlight® units are made from fully recycled PVC films. The products are assembled in our plant in France or directly on site. The units are simply installed next to one another, without any connectors.

Applications

– Retention basins under roads or green spaces

The purpose of the retention basin is to limit the inflow of rainwater and, through its buffering role, to avoid saturating the sewage networks and overflowing the overflow weirs.

– Infiltration basin

In the infiltration basin, water is released directly by infiltration into the soil: the lower surface of the cells is in hydraulic contact with the soil (but protected by a permeable geotextile) and the water infiltrates directly into the soil.

Patented diffusion system

The stormwater runs off into the pipes, and into the manhole. The water flow controls the operation of the reservoir:
  • For fine or moderate rain, the water flows in the drain (By-Pass effect)
  • In the event of heavy rain or storms, the water flows in the drain and fills the GEOlight units through the perforations at the top.

The GEOgrid protects GEOlight against stones and fill, and the vent enables the evacuation of air when the reservoir is filled.
