Geoweb is een product dat instabiele ondergronden stabiliseert. Geoweb is een honinggraad structuur samengesteld uit gelaste HDPE stroken die cellen vormen en op deze wijze de vulling samenhouden. De vulling kan bestaan uit doorgroeibare producten zoals zand, grond, puin en grind. Als niet doorgroeibare optie kunnen de cellen zelfs met beton gevuld worden. Geoweb is geschikt voor erosiecontrole en grondstabilisatie van (tijdelijke) wegen, spoorwegen, voetpaden, waterlopen, keermuren, taluds, wegverbreding etc.

Constructies waarin Geoweb is toegepast zijn geschikt voor hogere belastingen en hebben een natuurlijke afvoer van het oppervlaktewater, ze kenmerken zich als een duurzame oplossing met lage exploitatie- en lage onderhoudskosten.

Geoweb Road Verge Control System

Unprotected road verges unable to support active vehicle loads can potentially become very dangerous. To avoid rutting and to stabilise poor road verges, GEOWEB® is a proven and cost-effective solution for providing stable, vegetated road verges.
The GEOWEB® and appropriate infill material provide an effective system which combines flexibility and stability. Confining infill material in the system’s structure reduces the effects of vertical loads by transferring them into horizontal loads up to
a certain degree. The resulting horizontal load distribution minimizes stress on the subsoil and significantly reduces deformation compared with conventional unconfined soils respectively substructures/constructions.
Benefits of 3D confinement
The GEOWEB® system is a three-dimensional honeycombed structure made of high density polyethylene (PE-HD). The overall stabilising effect is achieved by each single cell and the cell walls. The GEOWEB® cell hoop strength, passive resistance of adjacent filled cells, and frictional interaction between the infill material and the cell walls contribute to the support structure. When concentrated or distributed loads are imposed on the surface, the cell walls retain the infill material preventing shearing and horizontal movement, which reduces lateral deformation. Due to the structure’s retaining influence, the granular infill material achieves a higher stiffness and apparent cohesion. The benefit of GEOWEB®-stabilised construction compared to a non-stabilised system is a much higher load-bearing capacity.
Infill material
Depending on the required construction finish (vegetated/ non-vegetated) and the anticipated loads and frequency, a variety of compactable filling materials are possible. For vegetated road verge stabilisation, a mixture of topsoil and aggregate/ gravel is recommended to provide stability and a medium for vegetative growth.

Geoweb Bank and Shoreline Protection System

The GEOWEB® Shoreline Protection System stabilises soils on shoreline embankments, creating a structurally stable environment for infill. The system minimizes erosion problems caused by water contact, surface flow and small scale wave action.
• Confines and reinforces the upper soil layer.
• Provides resistance to erosive conditions and slip forces.
• May be integrated with a turf reinforcement mat (TRM) for higher protection for vegetation.
• Protects geomembranes on ponds, or stormwater/wastewater containment basins.
The GEOWEB® system can be designed to provide long-term stability with sustainable vegetation,
permeable aggregate or hard-armoured concrete.
Vegetated Protection:
The GEOWEB® system with established vegetation protects embankments against mild wave and tidal
forces. With a TRM cover, offers better resistance to soil loss caused by soil saturation.
Aggregate Protection:
Confinement in the GEOWEB® structure allows smaller, less-expensive materials to be used, and on
steeper slopes than when unconfined.
Concrete Hard-Armor Protection:
With concrete infill, the GEOWEB® system is a less costly, flexible alternative to articulating block systems.

Geoweb Earth Retention System

Design retaining walls with natural aesthetics that perform in less-than-ideal site conditions. Construct structurally-stable, low-impact development retaining walls that reduce stormwater runoff and help meet green building goals.

The multi-layered Geoweb® Retaining Wall System creates economical and structurally-sound retaining walls that meet all design requirements and desired aesthetics through a terraced vegetated face.

Typical Wall Structures

  1. SteepenedSlopes
  2. Geocomposite Retaining Walls
  3. Gravity Walls
  4. Multi-Layered Channel System
  5. Economic Benefits

Why contractors prefer Geoweb retaining wall systems:

Use of less expensive on-site infill materials saves cost.
Faster construction saves cost:Compact and light-weight sections are easier to handle, deploy and construct even in difficult-access or remote locations.
Handling of light-weight sections compared to heavier block systems reduces worker down-time.
Sustainable Vegetation

The Geoweb retaining wall system’s open-celled horizontal terraces create a natural environment for sustainable vegetation. The vegetated system allows rain water to collect through the wall fascia, maximising stormwater collection, and minimising runoff.

Geoweb Channel Protection System

The GEOWEB® Channel Protection System stabilizes and protects channels exposed to erosive conditions of all types and can be designed with appropriate infill types to withstand even the highest velocities.
Channel Options

Vegetated Protection:
Replaces costly, higher-maintenance rip-rap with lowermaintenance, less expensive, stabilized vegetation. Effective in low-flow channels and when low-to-high intermittent flows occur. With a TRM, the vegetated GEOWEB® system can withstand velocities as high as 9m/sec. Ideal for drainage ditches, swales and stormwater channels.
Aggregate Protection:
Aggregate confined in the GEOWEB® system is far more stable than when unconfined. As a result, rather than using large, difficult to handle rip-rap, smaller and less expensive infill can be used in low-to-challenging flow conditions.
Concrete Hard-Armor Protection:
Concrete-filled GEOWEB® structures are ideal for channels exposed to severe hydraulic stresses. Concrete is poured in the structure onsite, creating an easy-toinstall, flexible yet hard-armored system that is less costly than pre-formed concrete systems.
Multi-Layered Protection:
GEOWEB® multi-layered, vegetated channels create natural living retaining walls that can withstand high flows for short durations. They tolerate differential settlement while maintaining their structural integrity, and are quicker and easier to install than typical block systems.
GEOWEB® Key Applications
• Swales & Drainage Ditches
• Storm Water Diversion or Containment
• Process Water Channels or Containment
• Spillways
• Culvert Outfalls
• Intermittent or Continuous/Low- to High-Flow Channels

Atra® Tendons & Tendon Clips

ATRA® Tendon Clips are load transfer devices that transfer slope gravity forces from the Geoweb cell wall to the tendon.

Specify ATRA Tendon Clips to gain the advantages:
ATRA Tendon Clips connect and “lock” securely through the Geoweb cell wall slots allowing for preassembly at the top of slope, reducing worker strain and speeding installation.
The tendon loop is much easier to complete with the ATRA Tendon Clip, ensuring the tendon remains tightly wrapped.
The ATRA Tendon Clip’s strong design reduces by half the number of clips or load transfer devices required per Geoweb section, saving time and money for the contractor.
The ATRA Tendon Clip is Presto’s preferred device for load transfer when tendons are required.
The secure connection ATRA Tendon Clips make with the Geoweb cell wall allows for easier preassembling of the clips before moving and expanding the Geoweb sections on slopes-a huge time saver
