InfraWeb is a lightweight, expandable cellular confinement system which creates an erosion barrier or structural foundation.
Cellular Confinement Systems were first developed by the US Army in the 1970’s in order to construct roads, airstrips, etc. on soft soil and under wet weather conditions.
It was determined that placement of thin walled, sand filled cells over a soft subgrade provided significantly greater load bearing capability than compacted soil alone. High density polyethylene (HDPE) was found to provide an optimal solution in terms of strength, durability, ease of handling and economics.
Cellular confinement systems have since been used extensively in a variety of applicaitons such as road building, ground stablisation, erosion control and landscaping.
The InfraWeb confinement system can be used with a variety of infill materials - soil, aggregates, concrete etc. depending on the application.
Applications
Benefits
Vehicular traffic over unprotected areas within the tree root protection zones of existing trees causes compaction of sub soils leading to reduced voids within the soil structure. This reduces air and water transfer to the roots themselves which can ultimately lead to the root structure declining and the eventual loss of the tree.
View
Erosion occurs when the forces exerted by water of wind dislodge and transport away soil particles.
View
InfraWeb cellular confinement systems serve to spread loads that are imposed upon the system. Furthermore, in many instances it is possible to use locally avaliable, inexpensive aggregates in a multitude of stabilisation projects such as: roads, access lanes, runways, car parks, railway track bedding, beddinf for sewer and water pipes.

In order to stabilise very steep slopes, retaining walls are constructed. Traditional retaining wall structures are constructed of concrete blocks or wooden facias combined with one or more layers of reinforcement (geogrids, metal strips etc.) extending into the soil mass.
