Presto

Manufacturer of the GEOWEB® Cellular Confinement System. Alcoa Geosystems’ quality management system is certified to ISO 9002.

Alcoa Geosystems’ GEOWEB® system is an engineered three-dimensional polythylene, honey-comblike structure that provides cost-effective solutions to load support, slope and channel protection, and earth retention problems through confinement of soils.

The perforated Geoweb® system features an exclusive pattern of cell wall perforations designed to provide optimal interlock with infill materials and lateral drainage.

In load support applications, the Geoweb® system stabilizes the infill, providing a load distribution system over weak soils, base stabilization for paved surfaces and surface stabilization for unpaved surfaces. In slope and channel protection applications, the system provides increased slope stability to embankments, shoreline revetments, dikes and levees, dam faces, and landfill covers. When layered, the system becomes an earth retention system, meeting all structural requirements and aesthetics through a completely vegetated face.

Perforated Textured GEOWEB® System
- Small (GW20v), mid (GW30v), and large (GW40v) cell sizes, 75mm (3 in), 100 mm (4 in), 150 mm (6 in) and 200 mm (8 in) cell depths
- Increases frictional interlock with aggregates and concrete
Increases root lock-up with vegetated systems and provides better lateral drainage

Non-Perforated Textured GEOWEB® System
- Textured surface improves performance with fine grain infill

Polymeric Tendons
- Provides increased stability on embankments and slopes or when a geomembrane underlayer or naturally hard soil/rock prevents anchoring with stakes

ATRA® Clips
- Used with rebar stakes, eliminates the task and cost of forming J-pins
- Provides an in-line, easier to drive anchor pin

SPECMaker® Tool
- Specification development tool for creating 3-part Geoweb® system or generic geocell specifications.
