Geoweb® Cellular Confinement System
Presto® GeoSystem’s Geoweb® Cellular Confinement System is excellent for use in the applications of slope and channel protection, load support and earth retention. Presto® Geoweb® is the original cellular confinement system, and is the only fully engineered cellular confinement system available. Made of durable polyethylene strips that are fusion welded in a fashion, that when expanded, create honeycomb-like cells. These cells dramatically enhance the performance of various infill materials including soils, aggregates and concrete. Presto® GeoSystems is the leader in cellular confinement technology pioneering advancements that include the introduction of perforated and textured geocells, integration of High Strength Polymeric Tendons as well as the ATRA® Anchoring System. GSI and Presto will work together to assist you in proper selection and design methodology with the Presto® Cellular Confinement System.
Presto® Cellular Confinement System is available in 3 cell sizes and various depths for a variety of applications. GW20V, GW30V and GW40V are sold in expandable sections of various lengths.
The GW20V cell has a nominal expanded area of 45 sq. in. and measures approximately 9 in x 10 in. Sections of GW20V are 10 cells wide and available 18, 21, 25, 29, 34 and 40 cells long.
