Presto GEOWEB - Erosion Control & Slope Protection Solution
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.
Geoweb 3D Vegetated Slope Protection Solutions
Builds Steeper Slopes
GEOWEB 3D confinement allows construction of steep slopes using topsoil or other infill.
Resists Sheet Flow Erosion
Confined infill in the 3D GEOWEB cellular structure is unaffected by sheet flow over the surface, preventing erosion.
I-Slots for ATRA Components
GEOWEB cell wall I-Slots facilitate use of stronger design and faster installation devices. Join GEOWEB sections with ATRA keys, thread tendon and transfer load from the GEOWEB sections to tendons with ATRA tendon clips.
Cellular Network Creates Stable Growth Environment
The GEOWEB 3D cellular network isolates each cell to create an eco-zone protected from erosive forces.
Perforations Allow Root Lock-up
Up to 20% of the GEOWEB wall is perforated to stimulate cross-root growth delivering a strong geo-vegetated solution.
Allows Select Vegetation & Plantings
Slopes can be designed with special vegetation type, flowering plants or even arid-resistant vegetation to meet climate conditions.
Suspends Vegetation Over Liner Systems
Using tendons and ATRA tendon clips, support a GEOWEB solution over liners without puncturing the impermeable liner with stakes.
Georunner Surface Flow Mats Compared to Alternative Mats or Rip Rap
More Economical
GEORUNNER mats are half the cost of rip rap and lower cost than other transition mats in the market.
Better Vegetation Growth
Compared to ScourStop or similar transition mats, the open lattice design of GEORUNNER mats allows for dense, stabilizing vegetation with better root engagement and reinforcement.
Side-to-Side Connection
GEORUNNER mats are connected side-to-side with overlapping tabs and spring steel clips for an integral connection. Other mats do not have tabs and recommend laying their units side to side and joining with plastic straps, which can slide and separate.
End-to-End Connection
GEORUNNER mats are connected end-to-end with rivets with overlapping tabs, creating a flush connection. Other mats recommend ‘shingling’ which can lead to increased turbulence.
Industry Standard Anchors
Duckbill anchors (300 lb pullout), Gripple and stainless steel cable are GEORUNNER anchor components. Other mats use plastic straps that are susceptible to breaking, long term strain and cutting.
Natural Appearance
GEORUNNER mats placed over a TRM offer similar resistance as rip rap, but with a naturally vegetated appearance that supports unimpeded access by mowing / lawn maintenance equipment. Rip rap is prone to collection of garbage and debris and is difficult to maintain.
Performance Backed by Research
Testing at Colorado State University verified the GEORUNNER (unvegetated) can withstand up to 30 fps when vegetated. a 2-3X improvement over TRM’s.
GEOWEB Erosion Protection of Slopes and Shorelines
- Delivers stability and long-term sustainability of embankment materials.
- Confines and reinforces the upper soil layer to resist erosive conditions and sliding forces.
- Saves costs by using confined infill, which allows steeper slopes to be designed and constructed.
GEOWEB Erosion Protection of Channels
- Stabilizes and protects channels exposed to erosive conditions of all types.
- Withstands velocities as high as 30 ft/sec (9m/sec) when combining GEOWEB vegetated system with a TRM. See Colorado State University Research
- Replaces costly and high-maintenance rip-rap with more attractive stabilized vegetation in drainage ditches, swales and stormwater channels. See Colorado State University Research
- Reduces aggregate requirements, allowing smaller, less-expensive aggregate.
- Provides hard, durable protection for higher velocities when infilled with concrete.
- Stabilizes and minimizes the sliding potential of infill materials over impervious liners.
- Prevents damage to and degradation of a liner.
- Maintains strength and integrity even when subject to settlement.
- Protects grass from concentrated surface flow.
- Easily placed and anchored locking mat system.
- Allows dense stabilizing vegetation growth with open-hole design.
- Light-weight and less-costly, GEORUNNER mats are preferred by contractors over concrete mat systems.
