The Presto Geoweb® load support system is a highly effective, economical solution to unacceptable road, parking , and yard surface problems that result from subgrade material failure or base material instability. Under concentrated or distributed loads, the three-dimensional cellular structure confines infill material and controls shearing, lateral and vertical movement of the infill material.

As a base stabilization system under pavement, the Geoweb® material significantly improves pavement life cycle costs. When confined, base material requirements can be reduced by 50% or more by substantially reducing the loading on sub-surface soils. As a result, reduced excavation and granular infill needs reduce overall installation cost.

As a surface stabilization system, the Geoweb® structure distributes surface pressures for dynamic and static loading, controlling rutting and reducing long-term maintenance requirements and costs. Using permeable infill with a high porosity, the system offers environment and storm water management benefits.
With topsoil/aggregate infill, Geoweb® material can create a vegetated surface that supports occasional loads.

Geoweb® system benefits

• Produces a stiff base with high flexural strength; acts like a semi-rigid slab by distributing loads laterally.
• Minimizes impact of differential and overall settlement even on low-strength subgrades.
• Increases effective structural number, reducing fill depth requirement by 50%.
• May allow use of poor-quality granular fills in place of more costly imported materials.
• With permeable infill, reduces storm water runoff and effectively performs as an on-site storm water retention/detention “basin” storage, reducing need and costs for storm water ponds.
