Electrical Substation Platforms

Build stable aggregate platforms for substation access and utility equipment.

Electrical substations require reliable access for maintenance vehicles, utility crews, and equipment. These areas are often exposed to heavy loads, soft soils, saturated conditions, and weather extremes that can lead to rutting, erosion, washouts, surface ponding, and recurring maintenance.

Aggregate surfaces are commonly used in substations to support drainage and help manage step and touch potential concerns. However, unstabilized aggregate can shift, rut, or hold surface water under vehicle traffic and changing site conditions.

The GEOWEB® Soil Stabilization System creates long-lasting aggregate platforms by confining infill within a 3D cellular structure. This helps prevent aggregate movement, improve load distribution, and maintain a stable surface without the need for concrete or asphalt. When used with open-graded aggregate, GEOWEB can also support permeability and help reduce surface ponding.

For porous aggregate access areas where drainage and surface stability are priorities, GEOPAVE® Gravel Pavers can also be used to stabilize aggregate and help reduce rutting. Together, these systems support durable, low-maintenance surfaces for substations, switching stations, utility yards, and equipment staging areas

Key Benefits
