SALIENT CHARACTERISTICS (Brand Name or Equal)

A. Geocell (Brand Name or Equal to Geoweb GW30V80829P; 8” deep x 8 cells wide x 29 cells long; Long Normal Dimensions 8.5'x27')

· 3D Cellular Network: Interconnected cells confine soils, aggregates, or concrete horizontally and vertically to prevent lateral movement and shear.

· Perforated Cell Walls: Engineered hole patterns allow lateral drainage in saturated soils, increase root lock-up for vegetation, and improve frictional interlock with aggregates or concrete.

· Textured Surfaces: Textured cell walls enhance friction against infill materials to maximize stability and structural integrity.

· High-Density Polyethylene (HDPE) Composition: Made from virgin or high-grade polymer material providing high tensile strength, environmental stress crack resistance, and durability against natural forces.

· Specialized Accessories Integration: Utilizes components like ATRA Keys for fast panel connection and tendon clips for anchoring on steep slopes or geomembranes.

· Flexibility and Conformability: Flexible panel design accommodates differential soil settling and matches natural landscape contours.

B. Anchors (Brand Name or Equal to ATRA anchors speed stakes, 16”)

· One-Piece Molded Unit: They are injection-molded as a single unit. This entirely eliminates the need for on-site assembly, bending rebar, or attaching separate clips.

· Specialty Polymer Alloy: Made from a highly durable, high-density polyethylene (HDPE) polymer blend. This makes them fully corrosion-resistant and non-conductive, allowing them to survive long-term in wet, acidic, or saltwater environments where steel would degrade.

· Engineered Barbs: The shaft features built-in barbs and an optimized shape that provides superior resistance to sliding, uplift forces, and soil pull-out compared to smooth steel.

· Rebar Equivalency: Due to their specialized anchoring shape, they outperform traditional steel rods.

· High Strength: They feature a minimum tensile strength of 14.5 kips (100 MPa) and a minimum bending strength of 575 lbf (2,550 N).

· Fast and Low-Impact Driving: The stakes feature a pointed tip that easily punctures underlying geotextile fabrics. They are designed to be driven rapidly using pneumatic Hilti or SDS-compatible power drivers outfitted with a specialized ATRA Gad attachment.

· Logistical Advantages: Being made of polymer, they are substantially lighter than steel rebar. This significantly reduces freight shipping costs and minimizes worker fatigue during manual handling on slopes.

· Flat Flanged Head: The top of the stake features a flat polymeric head. Unlike exposed, sharp rebar "J-hooks," this flat head creates a flush, secure connection over the geocell wall and eliminates the risk of tire punctures in permanent load-support applications.

C. Connectors (Brand Name or Equal to ATRA keys)

· High Joint Integrity: It is engineered to be three times stronger than industrial staples or zip ties.

· Failure Prevention: The design provides robust resistance to the three primary modes of mechanical junction failure: shearing, splitting, and peeling.

· Anti-Separation: The interlocking connection distributes load transfers permanently, effectively eliminating the risk of a "zipper effect" where individual staples disengage under stress.

· High-Density Polyethylene (HDPE): Molded from a non-reactive, chemically inert polymeric material, the keys will not corrode, rust, or degrade over time.

· Weather & UV Resistant: Formulated to withstand harsh environmental exposure, weathering, and ultraviolet radiation, ensuring the connection lasts for the full lifespan of the geocell installation.

· Tool-Free, Quick Installation: ATRA Keys are three times faster to install than staples. They fit seamlessly into the predefined "I-slots" of GEOWEB walls and require only a simple 90-degree manual turn and lock mechanism.

· Single-Worker Operation: Standard stapling usually requires a two-person crew (one to hold sections together, one to operate the compressor/stapler). The ATRA Key requires only one installer.

· No Heavy Equipment: It completely eliminates the need for air compressors, generators, pneumatic hoses, or power sources on-site, significantly cutting equipment costs and improving mobility on steep slopes.

D. Nonwoven Geotextile (Brand Name or Equal to Mirafi 160N, 15' × 300' rolls)

· Fabric: needle‑punched polypropylene nonwoven; shall meet AASHTO M288 Class 2 survivability.

· Strength/survivability (MARV): grab tensile ≥160 lb MD/CD; elongation ≥50%; trapezoid tear ≥60 lb; CBR puncture ≥410 lb.

· Hydraulic properties: AOS ≤ US Sieve 70 (0.212 mm); permittivity ≥1.5 s⁻¹; flow rate ≥110 gal/min/ft².

· UV resistance: ≥70% tensile strength retained at 500 hours (≥70% minimum required).

· Roll size: nominal 15' × 300' (500 yd²).

· Equal product note (geotextile): “Equals” shall meet all AASHTO M288 Class 2 survivability and hydraulic values listed above and provide OEM datasheets confirming test methods and MARV values.

· Submission with quote (for 52.211‑6 evaluation)

· Provide OEM technical data sheets for each item that explicitly show compliance with the salients (e.g., ASTM D5199 for geocell strip thickness; ASTM D1693 for ESCR; ASTM D4632/D4533/D6241 for nonwoven strength; ASTM D4491 for permittivity/flow; AASHTO M288 Class 2 statement).

· Identify brand/make/model for each offered item and clearly describe any modifications used to meet these requirements.
