The Permavoid Biomat units are similar in structure to standard Permavoid geocellular units for surface water storage, but with the inclusion of an oil-intercepting floating mat. The Biomat treats residues or emulsified oils in the surface water and allows clean water to pass to the attenuation and infiltration system.

Performance

  • Oil retention 56g/m2
  • Compressive strength up to 71.5 tonnes/m²
  • 95% void ratio for high storage capacity and lower excavation and disposal costs
  • High-strength, consistent structural raft in accordance with BS7533-13:2009
  • Up to 50-year design life

Technical specification

Oil retention
56g/m2

Material
Manufactured from recycled polypropylene

Compressive strength
Vertical: max. 715kN/m2
Lateral: max. 156kN/m2

Unit dimension
708mm (L) x 354mm (W) x 150mm (D)

Unit weight
3kg
