Abstract
Abstract A cellular earth confinement material having texturized surfaces in the cells provides improved structural integrity and reduced long-term settlement in single layer and multilayer filled cell structures. The texturized earth confinement structures can be used with a wide variety of fill materials including sand, soil, cement, asphalt and gravel. The optimum texture of the surface varies depending on the size, shape, and type of fill particles, and the density of the fill.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
112 words
A cell material structure for confinement of earth material, comprising: a plurality of plastic strips bonded together on their faces in a side by side relationship at bonding areas which are staggered from strip to strip such that the plurality of strips may be stretched in a direction perpendicular to the faces of the strips to form a layer of cells open at the top and bottom; said strips comprising two outside strips and one or more inside strips; said strips comprising at least one texturized surface having a texture which creates an angle of friction of about 20 degrees to about 60 degrees between the surface and the adjacent fill material.
Claim 2
Dependent Claim
112 words
A cell material structure for confinement of earth material, comprising: a plurality of plastic strips bonded together on their faces in a side by side relationship at bonding areas which are staggered from strip to strip such that the plurality of strips may be stretched in a direction perpendicular to the faces of the strips to form a layer of cells open at the top and bottom; said strips comprising two outside strips and one or more inside strips; said strips comprising at least one texturized surface having a texture which creates an angle of friction of about 20 degrees to about 60 degrees between the surface and the adjacent fill material.
Claim 3
Dependent Claim
15 words
The cell material structure of claim 1 wherein each inside strip comprises two texturized surfaces.
Claim 4
Dependent Claim
17 words
