PermaShieldTM Product Specifications
Patented Design Characteristics:
• Shape: Isosceles Trapezoid Prism —Turns lateral earth pressure or lateral water pressure into a
downward force due to the angular wall design. (See illustration A below)
• Heights available: 2', 3', 4', and 6' (See illustration B below)
• Section Length: 50'
• Stackable to any height. (See illustration C below)
• Multi -cellular design: Isolates damage to a cell to keep the section from failing. Each 50' section
is separated every 2' by a sewn baffle that acts as a natural expansion joint. Each 50' L section
includes 25 cells. (See illustrations D and E)
• Can accept a variety of fill materials. Sand or other earthen materials, or concrete for
permanent applications. (See approximate weights of sand filled and concrete filled section
heights in illustration F)
• Mounting knobs to mount entire 50' L section on installation platform for quick installation.
(See illustration G)
• Installation Platforms for sand and concrete materials. (See illustrations H and 1)
Product Material:
8 oz Woven Polypropylene (100% virgin material)
• UV resistance: depending on direct sunlight exposure: 70% after 2000 hours (For dune
applications, PermaShield will be buried under sand that forms the dune.)
• Chain Stitching
Connectivity: Ability to connect one 50' section to another:
• Male connection on one end; Female connection on the other end (See illustration J)
• Secured together with strapping with "D" rings as seen in the picture below. (See illustration K)
