Aggregate confinement system
Presto’s perforated Geoweb cellular confinement system features an engineered pattern of perforations in the cell wall. This hole pattern provides increased frictional interlock with coarse aggregates, crushed rock, and concrete.
In vegetated systems, the perforations increase root lock-up, creating a more stable vegetated mass and overall healthier soil environment. The perforations allow lateral drainage through the system, thereby enhancing the performance of the system in saturated soil conditions.
The Geoweb system enhances system performance in slope and channel protection, earth retention, and load support applications. The multi-layered earth retention system is used for a wide range of design requirements and site conditions. The system’s flexibility allows it to withstand large differential settlements and conform to a contoured landscape while typically using on-site infill materials. The system’s outer cells, when filled with topsoil, provide an ideal environment to support vegetation.
