Channel Protection

The Presto Geoweb® system provides a wide variety of　economical, flexible protection treatments for open channels and　hydraulic structures. The system provides stability and protection of　channels exposed to erosive conditions ranging from low-to-high　flows, either intermittent or continuous.

  • Greatly improves the hydraulic performance of conventional protection materials such as aggregate, rip-rap and topsoil/vegetation by confining them within the cellular structure.

  • With concrete infill, produces a flexible slab for a long-lasting armored channel lining at a lower cost than articulating block systems.

  • Can be designed for specific site conditions based upon compatibility with local environmental, ecological and aesthetic requirements, maximum anticipated flow conditions, and associated hydraulic stresses.

  • Surface roughness and hydraulic efficiency of the lining system can be changed to control flow.


Geoweb® system benefits

Cost-effective structure confines selected infill material to resist anticipated hydraulic flows and associated stresses.

  • Supports vegetation in low-to-high intermittent flow channels.

  • Allows the use of on-site aggregates in low-to-moderate flow channels, reducing construction costs.

  • Provides protection to geomembrane-lined channels and containment systems.

  • With concrete infill, provides flexible, inexpensive hard-armored protection against severe high-flow conditions, wave action and associated stresses.


INFILL OPTIONS

A variety of infill materials can be used with the Geoweb® system based upon the requirements of the specific project/problem.

  • Topsoil with various selected vegetation.

  • Aggregates of varying size and gradation.

  • Concrete of various strengths and surface finishes.

  • Combinations of the above to meet special conditions.


TYPICAL APPLICATIONS

  • swales and drainage ditches

  • storm water diversion or containment

  • process water channels or containment

  • spillways/down chutes/drop structures

  • culvert outfalls

  • intermittent or continuous/low to high flow channels


Slope and Shoreline Protection

The Presto Geoweb® slope and shoreline protection system is an economical solution to challenging slope-surface stability problems while meeting a wide range of performance and aesthetic requirements. The system provides a means of fully-vegetating slope surfaces that otherwise could not support sustainable plant life. Single or multi-layered systems offer a broad range of surface protection treatments. The systems provide long-term stability and effectiveness of vegetated, permeable and armored slope surfaces.


Geoweb® system benefits

  • The three-dimensional structure confines selected infill material to resist down-slope movement of embankment materials and anticipated hydraulic flows.

  • Minimizes the movement and migration of embankment materials by functioning as anchored containers in the upper soil layer.

  • Inhibits erosion and controls rill and gully formation, particularly in areas of concentrated flow over erosive soils.

  • Increases vegetation stability on slopes by interlocking with the vegetative root zone, or confining and interlocking aggregate or concrete for permeable or hard-armored solutions.


INFILL OPTIONS

A variety of infill materials can be used with the Geoweb® system based upon the requirements of the specific project/problem.

  • Topsoil with various selected vegetation.

  • Aggregates from sand and gravel to larger rock or stone.

  • Concrete of various strengths and surface finishes.

  • Combinations of the above to meet special conditions.


TYPICAL APPLICATIONS

  • Cut or fill embankment slopes

  • Containment dikes and levees

  • Shoreline revetments

  • Geomembrane protection

  • Landfill lining, covers, and drainage

  • Storm water basins

  • Waste water lagoons

  • Dam faces and spillways

  • Abutment protection


Retaining Walls / Earth Retention

The Geoweb® earth retention system provides an economical, structurally-sound, green alternative to conventional retaining wall systems. The Geoweb® system meets all design requirements while providing desired aesthetics through a terraced face where vegetation can flourish, creating a natural living wall. The Geoweb® system adapts to a wide range of design criteria and construction requirements, meeting site challenges even when subgrade soils are compressible. With a high percentage of open area, ability to use on-site fills and efficient transportation of materials, the Geoweb® system is an eco-friendly solution for a wide variety of retaining walls.


Aesthetics of sustainable vegetation

The multi-layered Geoweb® system features horizontal terraces with exposed outer fascia cells, creating a natural environment for selected sustainable vegetation. The vegetated system reduces storm water runoff by allowing rain water to fall on the exposed horizontal soil terrace, maximizing water collection.


Natural-colored facing

Standard wall sections are available with green, tan, or black fascia colors to blend with natural environments. The polyethylene is ultraviolet-light-stabilized to resist color fading, and increase system durability and quality performance to meet typical engineering requirements.


TYPICAL APPLICATIONS

  • Vegetated retaining walls

  • Bioengineered walls

  • Steepened embankments

  • Dikes and levee protection

  • Culvert headwalls

  • Vegetated channel structures

  • Change-in-grade landscape walls

  • Resource protection barriers

  • Sound berms


Load Support

The Presto Geoweb® load support system is a highly effective, economical solution to unacceptable road, parking , and yard surface problems that result from subgrade material failure or base material instability.
Under concentrated or distributed loads, the three-dimensional cellular structure confines infill material and controls shearing, lateral and vertical movement of the infill material.

As a base stabilization system under pavement, the Geoweb® material significantly improves pavement life cycle costs. When confined, base material requirements can be reduced by 50% or more by substantially reducing the loading on sub-surface soils. As a result, reduced excavation and granular infill needs reduce overall installation cost.

As a surface stabilization system, the Geoweb® structure distributes surface pressures for dynamic and static loading, controlling rutting and reducing long-term maintenance requirements and costs. Using permeable infill with a high porosity, the system offers environment and storm water management benefits.
With topsoil/aggregate infill, Geoweb® material can create a vegetated surface that supports occasional loads.


Geoweb® system benefits

  • Produces a stiff base with high flexural strength; acts like a semi-rigid slab by distributing loads laterally.

  • Minimizes impact of differential and overall settlement even on low-strength subgrades.

  • Increases effective structural number, reducing fill depth requirement by 50%.

  • May allow use of poor-quality granular fills in place of more costly imported materials.

  • With permeable infill, reduces storm water runoff and effectively performs as an on-site storm water retention/detention “basin” storage, reducing need and costs for storm water ponds.


TYPICAL APPLICATIONS

  • Permanent and temporary site access roads

  • Permeable, load-supporting surfaces

  • Intermodal/port facilities

  • Transportation/storage yards

  • Roadway shoulders (Vegetated or porous aggregate)

  • Stabilized base for asphalt/modular block pavement

  • Stabilized drainage layer

  • Railroad track ballast/ sub ballast structures

  • Trails and walkways

  • Boat ramps and low water crossings

  • Pile cup structures

  • Foundation mattresses and pipeline protection
