TerraCell® 140

Material
TerraCell^® 140 is a perforated, textured geocell manufactured from High Density Polyethylene (HDPE) to the following minimum standards:

Fabrication
TerraCell^® 140 sections are manufactured from 58 strips of HDPE; each of appropriate height by 142 inches (3.6m) long. Typical panels are 29 cells long and 10 cells wide.
Cell walls are textured with a multitude of rhomboidal indentations with a surface density of 22 to 31 per cm2 (140 to 200 per in2). Perforations remove 16% ± 3% of the cell wall. Cell joints are ultrasonically spot-welded with 3 welds per inch uniformly spaced across the height of each strip. Seam strengths are the same across the entire height of the cell joint and meet the minimum tensile requirements below:

Seam Hang Strength
Seam Hang Strength – A 102 mm (4.0 in.) weld joint supporting a load of 72.5 kg (160 lbs.) for 30 days minimum or a 102 mm (4.0 in.) weld joint supporting a load of 72.5 kg (160 lbs.) for 7 days minimum while undergoing temperature change from 23° C (74° F) to 54° C (130° F) on a 1 hour cycle.

Dimensions
TerraCell^® 140, in expanded configuration, has nominal dimensions of 3, 4, 6 and 8 inch cell depths with an optimal width of 8.4 feet and optimal length of 21.4 feet. Optimal panel expanded area is 180 ft2 (16.7m2). Other panel lengths can be custom-made; panel length is simply a function of number of strips welded. Unexpanded spacing of weld joints is 14 inches. Optimal cell area is 10.2 inches by 8.8 inches nominal. Individual cell area is 44.8 square inches (289 cm2) nominal.

Additional Information
The quality control system used in the manufacturing of TerraCell^® is in compliance with ISO9001:2000 standards. TerraCell^® is licensed from the United States Army under Patent No. 4,797,026. Please contact Hanes Geo Components, or a TerraCell^® distributor for more information.
