Geoweb® Load Support System
ECONOMICAL 3D STRUCTURE STABILIZES INFILL MATERIALS
Construct roads over soft soils where quality infill is inaccessible or too costly. Stabilize challenging soft soils where traditional reinforcement methods are ineffective, or require deeper, more costly base materials.
The Presto Geoweb® Load Support System is a proven cost-effective solution for challenging soil stability problems. The Geoweb system is the original geocell system developed by Presto over 30 years ago for stabilizing sand with heavy loads. Today, the system is economical and highly-effective for solving unacceptable road, parking, and yard surface problems.
CONFINED INFILL IN THE 3D GEOWEB STRUCTURE:
- stabilizes infill material and controls shearing, lateral and vertical movement
- increases the effective structural number, allowing fill requirements and costs to be cut in half.
- may allow use of lower-quality, less costly on-site infill materials
Geoweb Load Support Research Results: reduces the thickness and weight of structural support element by 50% or more, allows subgrade materials to withstand more than 10 times the number of cyclic-load applications before accumulating the same amount of permanent deflection, provides over 30% stress reduction when supporting aggregate under pavement, distributes load between pilings reducing intersoil stress by 40%.
KEY LOAD SUPPORT AREAS
- Load Distribution System over weak soils
- Base Stabilization for paved surfaces
- Surface Stabilization for unpaved surfaces
LOW-ENVIRONMENTAL IMPACT SOLUTION
Reduce stormwater runoff and gain environmental Low Impact Development (LID) benefits by infiltrating and storing stormwater on-site. With permeable infill, the Geoweb system saves you the cost of traditional stormwater collection/storage systems by performing as an on-site stormwater retention/detention "basin". Permeable pavements are also eco-friendly, cooler pavements that reduce the heat island effect of traditional hard-surfaced pavements.
