Abstract
Geocells for moderate to low load applications are disclosed here. The geocells have a cell wall thickness of from 0.25 mm to 0.95 mm. They have a wall strength of from 3500 N/m to 15000 N/m.
Claims23
A geocell for medium-low load applications, characterized by a geocell wall strength, measured at 23 Celsius, of at least 3400 N/m and at most 19500 N/m;
- wherein the geocell is formed from a plurality of polymeric strips bonded together along seams so that a honeycomb pattern is formed when the strips are expanded;
- wherein the geocell has a seam split strength, measured at 23 Celsius, of at least 3400 N/m and at most 17500 N/m;
- wherein each polymeric strip has a wall thickness measured according to ASTM D5199 of from 0.25 mm to 0.85 mm;
- and
- wherein each polymeric strip is made of a polypropylene copolymer.
