SDS GEOlight® is widely recognised as the UK’s market leading water storage and attenuation / infiltration system.

SDS GEOlight® has been constructed entirely from post-consumer recycled PVC waste, which is normally destined for landfill.

In 1996 SDS GEOlight® helped create the foundations on which our company was built, when we completed our very first, high profile installations at the incredible Louvre Museum and Roland Garros tennis stadium in Paris. Fast forward to the present day and SDS GEOlight® is used in all sectors of the Private and Public sector construction industry. We work in partnership with the UK’s leading contractors to supply both bespoke and off-the-shelf water storage solutions, in a broad range of capacities, to a diverse range of sectors, from industrial and transportation to residential and commercial.

How does it work?

SDS’s unique GEOlight® geocellular systems have been specifically engineered to form underground water storage reservoirs in stormwater management schemes. The size of these reservoirs is determined by the quantity of water to be stored, while the layout of each scheme is designed to suit the individual characteristics and limitations of each site.

Constructed in a modular format, SDS GEOlight® systems can be used under a range of surfaces including grass, porous and standard paving, tarmac and concrete.

Looking to maximise water storage capacity? SDS GEOlight® always delivers – its highly permeable honeycomb structure provides a void ratio of over 95%. It also has high compressive strength and is available in two strengths as standard: 200 and 400 kN/m²; higher compressive strengths are also available from 600 to 1000 kN/m².

The water storage capability of SDS GEOlight® can be applied in many different ways:

Water recycling: Water can be pumped to a network of standpipes for irrigation as required.

Water pollution control: When combined with filtration devices and separators, SDS GEOlight® systems can replenish groundwater without the risk of contamination from oil, chemicals, hydrocarbons or suspended solids.

Embankment protection: SDS GEOlight® can be used to quickly form the base of embankments that only weigh a fraction of earth embankments (slope stabilisation).
