GEOWEB Permeable Load Support System

Project Name: High Steel Industrial Yard

Project Location: Lancaster, Pennsylvania

PROJECT SCOPE

The Presto Geosystems GEOWEB® Load Support System provided a low-maintenance, permeable load-support surface at a staging area for a 10-acre industrial yard site. Heavy traffic at the steel fabricator’s facility caused severe rutting of the existing gravel surface and costly long-term maintenance problems.

DESIGN CRITERIA

• Provide a permeable surface to control stormwater runoff.
• Control surface rutting and distribute heavy wheel loads.
• Function as a drainage layer when back-filled with an open aggregate.
• Be a cost-effective alternative to conventional concrete or bituminous concrete.

GEOWEB Geocells Structural & Performance Benefits

• Confines aggregate, preventing shear failure and both lateral and vertical movement of the infill material.
• Creates a stiff load distribution system, effectively reducing subgrade contact pressures and vertical
  deflections.
• Controls differential and total settlement over low-strength subgrades.
• Structural support systems may be reduced by 50 percent or more.
• Cell wall perforations facilitate lateral cell-to-cell drainage beneath traffic areas, resulting in better performance oversaturated soils.
• Stabilization of the permeable pavement surface translates to a reduction in maintenance costs.

ENVIRONMENTAL BENEFITS

With aggregate infill, the system:

• 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.
• Reduces the heat-island effect.
