Underground Stormwater Detention and Infiltration Chambers

Underground stormwater detention and infiltration chambers, regularising peak storm water flows, can be easily constructed by burying a volume of Laterlite Expanded Clay, suitably contained within a geotextile or geomembrane.

Thanks to the inherent strength of the expanded clay there is no need for a complex covering structure; the ground layers above the reservoir can bear directly on the expanded clay and can take the load of any type of activity (parking, roads, sports grounds, gardens, etc.).

Advantages:

 

  • Excellent water storage and drainage capacity thanks to the high intragranular and intergranular void content of expanded clay
  • Can be integrated into existing construction works to give a usable surface at ground level
  • Adapts to fill excavated volumes of any shape
  • Enables existing excavations to be reused
  • Minimal need to construct complementary structures
  • Stability and mechanical strength over time
  • Enables the stored water to be potentially accumulated and reused (with an impervious containment)
