IBRAN-A Soakaway/Attenuation Crate

Introducing the IBRAN-A Heavy Duty Soakaway and Attenuation Crate - a powerhouse solution designed to withstand the toughest conditions. Engineered from top-tier recycled polypropylene, this module boasts exceptional strength and remarkable water permeability while offering an expansive storage capacity.

Crafted to cater to a range of needs, including car parks, general duty, and traffic applications, this innovative system excels at capturing rainwater runoff. It adeptly stores the water temporarily, subsequently releasing it in a controlled manner. This discharge can serve a dual purpose: it can either gradually seep into the soil, functioning as a soak-away, or it can be gradually transferred to the sewer system, especially during heavy downpours.

During installation for use as a soakaway, these underground storage units are wrapped in a non-woven, needle-punched geotextile. This arrangement enables efficient water discharge into the sub-surface, replenishing groundwater levels. In scenarios where these units serve as attenuation systems, a secure geomembrane wraps around the tank, forming a watertight seal. To ensure longevity and to safeguard the membrane, a protective fleece layer is added to the assembly.

  • 5 x yellow Clips for connections between units.
  • 2 x red clips for connections between layers.
  • 16 x yellow closure caps for the top finishing layer of the structure.
