Presto Geosystems products

Presto Geosystems invented geocells in the late 1970’s and has been leading the geocellular technology ever since with important product advancements and design and construction accessories for higher performance and faster installation. Presto’s GEOWEB system is the industry’s ‘most complete geocell system’ designed with fully-engineered components to withstand the most challenging site problems. Made from high density polyethylene (HDPE) since conception, GEOWEB geocells offer the highest, longest-lasting performance of any geocell system in civil applications.

Make use of local fill to construct site access roads with the GEOWEB Load Support System allowing immediate access after installation. The GEOWEB system outperforms 2D reinforcement materials that require deeper, more costly base materials. GEOWEB 3D confinement system is equally beneficial for base stabilization under asphalt or concrete and can reduce base materials by 50% or more. Base stabilization, surface stabilization, over-excavation alternative, hard-surface pavements.

Stabilize the upper soil layer on embankments with the 3D GEOWEB Slope Protection System to resist sliding, prevent severe erosion caused by surface runoff, and allow steeper slopes to be built. Protect geomembranes on dams, landfills, and containment basins with the industry’s only complete geocell solution featuring the tendon and ATRA Tendon Clip support system. sustainable vegetation, permeable aggregate, hard-armored concrete, geomembrane protection.

Design GEOWEB channels with varying infill options that eliminates the need for costly rip-rap, gabions and articulated concrete blocks (ACBs). Prevent erosion on channel slopes exposed to intermittent or continuous flow conditions with single-layered or tiered GEOWEB Channels. With an overlying TRM, GEOWEB vegetated channels can withstand flows up to 30 ft/sec (9m/sec)!. Vegetated channels, permeable channels, hard-armor concrete channels, geomembrane protection.

Design vegetated reinforced and gravity walls that retain structural integrity even in poor base conditions with GEOWEB Retaining Walls. The GEOWEB system’s open-celled terraces create a natural environment for sustainable vegetation and allow storm water infiltration. GEOWEB walls conform well to landscape contours, are resistant to environmental degradation, and install 25-30% faster than MSE block walls. Presto offers design software to create GEOWEB Retaining Walls. Steepened slopes, reinforced walls, gravity walls, multi-layered channels.

High-Performance Transition Mats Stop Scour. Protect areas subjected to concentrated flows from scour and surface erosion with Georunner Mats. Fully interconnected mats protect underlying TRMs or erosion control blankets, allowing low-maintenance vegetation at pipe outfalls, drainage ditches and swales instead of costly, higher maintenance rip rap. Shorelines with moderate wave action are also protected from erosion with Georunner Mats. Swales & drainage ditches, pipe & culvert outfalls, spillways, stormwater channels, shorelines.

Offering unique solutions to prevent erosion problems caused by water contact, surface flow and wave action with the 3D GEOWEB Shoreline Protection System. Provides protect to geomembranes on ponds and in stormwater and wastewater containment basins. The GEOWEB System creates a stable environment for infill. Sustainable vegetation , permeable aggregate , hard-armored concrete , geomembrane protection.

3D Geocells Protect Embankments from Severe Erosion. Shore up steep embankments and prevent severe erosion on slopes and channels with the GEOWEB System. The 3D cellular network prevents sheet flow from causing scour and erosion on slope surfaces. Confinement of infill allows smaller rock or vegetation in place of larger, costly rip rap. With concrete infill, the system is a flexible, hard-armor solution - more economical than reinforced concrete or articulated concrete blocks (ACBs). For grassed areas prone to concentrated erosion, GEORUNNER Mats offer protection from scour. Sustainable vegetation, permeable aggregate, hard-armor concrete, geomembrane protection.

Highly-effective scour protection transition mats. Protect channel and shoreline embankments from scour caused by water fluctuations, surface flows and wave action. Protect culvert outfalls from scour caused by concentrated flows. Support natural vegetation growth.

How do Geocells Work to Stabilize Soils? Through an interconnected honeycomb-like network, 3D geocells confine and stabilize soils that would otherwise be unstable under loading. Geocells are efficient and economical for fast-built unpaved roadways and retaining walls, erosion control of slopes, and stormwater control in channels.
