Infraweb Tree Root Protection

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. Generally, in stabilisation end-use, the aggregate layer spreads the load imposed upon it, thus reducing the pressure exerted on the subgrade below a critical value. The InfraWeb system provides confinement throughout the depth of the aggregate, not just at the interface between the aggregate and the subgrade. The load spreading characteristics  of the aggregate is now enhanced due to the confinement of the aggregate. Therefore it is possible to use lower quality aggregate and/ or reduced quantity thus lowering costs.

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. This type of wall can be very expensive due to the cost of the facia materials. Instead, using InfraWeb serves as both the facia and the reinforcing element. The cells not only hold the soil in place, they also provide drainage throughout the structure.

While seeding and vegetation provide a cost effective solution on gentle slopes, the InfraWeb cellular confinement system provides an economical solution for severe erosion conditions when compared to a combination of geotextile and stone layers, gabions and the like.
