Permeable Aggregate Roads Offer High Environmental Benefits; With Low Environmental Impact.

Presto Geosystems’ GEOWEB® Load Support System offered a load distribution system on two low water crossings for Florida Power & Light. With FDOT #57 stone (crushed limestone) infill, the system creates a stable mat to support FP&L’s line trucks over wet, soft soil areas. The GEOWEB® 3D Confinement System creates a permeable pavement capable of supporting vehicular loads over non-load-supporting soils and functions as a stormwater retention system.

  • GEOWEB GW20V 6-inch Depth
  • Geotextile Separation Layer

GEOWEB Low Water System Environmental Benefits

With Clean Aggregate Infill, the System:

  • Confines granular infill, significantly improving load distribution.
  • Reduces stormwater runoff, promoting groundwater replenishment.
  • Functions as a natural stormwater retention system, allowing water to fill the aggregate voids and permeate into the existing ground.

Other Benefits:

  • Cell wall perforations facilitate lateral cell‐to‐cell drainage beneath traffic areas, resulting in better performance in oversaturated soils.
  • The stability of the pavement surface translates to a reduction in maintenance costs.
  • Controls shearing and lateral movement of infill material.
  • Supports the weight of vehicles and greatly reduces the compaction of underlying soils.
  • Confinement provides additional structural strength allowing for a reduction in overall cross‐section
    (50% or more).

Build Stable, Low Maintenance Access Roads Over Soft Soils

The GEOWEB® 3D system is a surface stabilization system that is easy to deploy, easy to install, and requires virtually no maintenance. Build access roads through environmentally sensitive areas or undeveloped land, while minimizing disturbance
