Presto GEOWEB - Geocells Cellular Confinement System

Presto`s Gary Bach worked with WES and devised a method to weld polyethylene strips to form a cellular structure. To this day, the military continues to use cellular confinement for access roads, tank trails, and bomb crater repair applications.

Presto introduced their cellular confinement system, trademarked GEOWEB®, to the civil engineering community in the early 1980`s. In the commercial market, cellular confinement has expanded to solve nearly an infinite number of problems - from steep slopes, shorelines, channels, and multi-layered vegetated retaining walls, to mining access roads, oil & gas roads, wind access roads, and railroads, intermodal yards & ports, dams and landfills... just to name a few.

Geocell System

Original Geocell Inventors

We are the original developers of geocells and Genuine GEOWEB, ultrasonic welding, perforations, texture, ATRA Keys, ATRA Anchors and ATRA Tendon Clips.

Virgin HDPE Material

Presto uses a unique blend of ONLY VIRGIN resin to assure consistent, reproducible, and long-lasting performance.

Strongest Weld Strength

GEOWEB material delivers welds that far outperform the competition with continually tested, traceable production for project assurance.

I-Slots for Fast Section Connection & Tendon Threading

Another Presto original, the oval I-slot allows the use of the ATRA Tendon Clips to transfer loads to tendons and ATRA Keys for faster, stronger geocell connections.

Flexible "Bend, Don`t Break" Material Characteristics

GEOWEB material is made from elastic resin, and unlike stiffer and recycled blends, delivers higher hoop strengths and passive earth resistance.

Storied History of Accredited Research

Since we stood on Virginia Beach with the US Army Corps of Engineers, the GEOWEB system has undergone over 100 studies over the span of 30 years and in five continents.

Manufactured Under Exacting ISO and CE Standards.

GEOWEB geocells are only manufactured by the highest quality equipment and certified facilities with quality and traceability guaranteed.

ATRA Stake Clips, Anchors & Drivers

ATRA Stake Clip Designed for Anchors, GEOWEB Cell Wall Connection

The anchor’s flanged arms make secure connections with the GEOWEB cell walls or tendons, unlike J-hooks that only make a loose connection.

ATRA Stake Clips Fit Standard Rebar/Rods

ATRA Stake Clips are available to fit either #4 rebar, or 10-12 mm diameter rod.

ATRA Stake Clips Fit GFRP Anchors

Glass-fiber reinforced polymer (GFRP) anchors in various lengths are available for corrosive environments.

ATRA Anchors Easier, Faster to Drive than J-Hooks

The ATRA Anchor is driven more easily than the curved J-hooks, where the driving force is offset from the center of gravity. ATRA Stake Clips and rebar drive true and easily as energy from the hammer is aligned 100% with the target.

Secure Connection with GEOWEB Cell Walls

The ATRA Stake Clip arm slides securely over the GEOWEB cell wall and positions the rebar along the cell wall offering full length resistance for the height of the cell wall.

Tendon Anchorage

ATRA Anchors with tendons are designed to resist sliding and/or uplift forces. The ATRA anchor arm secures the tendon, or the tendon may be wrapped around the anchor head for the most secure connection.

ATRA Driver is Efficient. Drives Anchors 10X Faster than with a Sledge Hammer

A special ATRA GAD attaches to pneumatic drivers and fits securely over ATRA Anchors for fast and efficient driving of anchors. Reduces worker fatigue. Beneficial in hard soils or with high anchor density. Available in Hilti or SDS Max formats.

Presto introduced their geocell trademarked GEOWEB to the civil engineering community in the early 1980’s. In the commercial market, geocells solve many site problems – from steep slopes to shorelines and channels to multi-layered vegetated retaining walls, mining, oil & gas, and wind access roads, railroads, ports, dams and landfills.

Several cell sizes and depths are available to meet project and application requirements.
