Permavoid Biomat comprises a high strength, low density, oil treating geosynthetic layer that floats on water and is designed to intercept and treat potential residual oils that may be present within emulsified surface water.
The floating mats are pre-installed within the Permavoid geocellular units and can be incorporated where required within the overall geocellular structure. Oils are aerobically bio-degraded and the system is designed to be self-maintaining for the life of the installation. Permavoid Biomat filters can also be incorporated into Polystorm cells to provide treatment for deeper attenuation and soakaway/infiltration applications.
