Presto Geosystems 6" Medium Cell GEOWEB Geocell, 230 SF Section

The Original Geocell Confinement System Stabilizes Soils
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.

PRESTO GENUINE GEOWEB® GW30V - 150 mm (6 in Depth) Overview

Surface Treatment

Performance:  The polyethylene strips shall be textured and perforated such that the peak friction angle between the surface of the textured / perforated plastic and a #40 silica sand at 100% relative density shall be no less than 85% of the peak friction angle of the silica sand in isolation when tested by the direct shear method per ASTM D 5321.  The quantity of perforations shall remove 16.8% ±1.0% of the cell wall area.

Material:  The polyethylene strips shall be textured with a multitude of rhomboidal (diamond shape) indentations.  The rhomboidal indentations shall have a surface density of 22 – 31 per cm² (140 – 200 per in²).  In addition, the strips shall be perforated with horizontal rows of 10 mm (0.4 in) diameter holes.  Perforations within each row shall be 19 mm (0.75 in) on-center.  Horizontal rows shall be staggered and separated 12 mm (0.50 in) relative to the hole centers.  The edge of strip to the nearest edge of perforation shall be 8 mm (0.3 in) minimum and the centerline of the weld to the nearest edge of perforation shall be 18 mm (0.7 in) minimum. A slot with a dimension of 10 mm x 35 mm (3/8 in x 1 3/8 in) is standard in the center of the non-perforated areas and at the center of each weld.
