Polystorm Deep has been designed for use in trafficked applications such as lorry parks and industrial access roads. It has vertical compressive strength of 61 tonnes/m² and a lateral compressive strength of 14.6 tonnes/m². This allows for a deeper burial, and consequently a higher volume of water capture and storage. It can be buried deeper than any other Polystorm cell at a depth of up to 8m and can be value engineered as part of a hybrid system.
The Polystorm Deep modular cells are combined to form a structure that received rainwater collected from roofs or surface water drains. The rainwater is then either attenuated by the structure – when wrapped in an impermeable membrane, or infiltrated by the structure – when wrapped in a permeable geotextile.
Key Features & Benefits:
Vertical compressive strength of 61 tonnes/m² and the highest lateral compressive strength of any Polystorm unit
Ideal for retention, attenuation or infiltration applications with a suitable geomembrane or geotextile
Designed for trafficked conditions which require deeper burial depths
Allows for flexibility of shape – ideal for narrow strips or use in restricted areas
Can be used as part of a value engineered hybrid system in trafficked applications with Polystorm-R and Polystorm Xtra
Can be used as part of a value engineered hybrid system for non-trafficked applications with Polystorm Lite and Polystorm-R
Undergone testing in accordance to BBA certification
Integrated 160mm inlet and outlet
3D flow throughout the structure
95% void ratio
Light in weight yet robust – excellent Health & Safety and installation benefits
