Product Specification - GEOWEB® GW30V6 Walls
GENERAL
GEOWEBO wall sections are manufactured from textured, perforated strips of high density polyethylene that are bonded together to create
a network of interconnected cells. Fascia strips are non -perforated, UV -stabilized for long-term durability and are available in green and tan
colors. Fascia strips are also available with pre -punched I -slots for establishing consistent mechanical junctions across the face of the wall
using ATRA Key connectors. GEOWEBO walls can be used in a variety of earth retaining structure configurations including: 1) mechanically -
stabilized earth (MSE) walls; 2) steepened slopes; 3) multilayered systems; and, 4) gravity retaining walls.

Notes:
1) A 10D-mm (4.0 in.) wide seam sample shall support a 72.5 kg (160Is) load for a period of 7 days minimum in a a
temperature -controlled environment undergoing a temperature change on a 30 hour cycle from ambient room to Se C
(13D` F). Ambient room temperature is per ASTM E 41.
2) Junction efficiency determined as a percentage of junction performance (EN ISO 13426-1) to perforated strip
performance (EN ISO 10319).
3) Typical design value for clean granular infill material (i.e. - coarse sand or crushed aggregate). Consult with
manufacturer to confirm value for other types of infill materials.
4) Standard black HDPE strips. For tan/green fascia strips, hindered amine light stabilizer (HAILS) content will be 2.0%by
weight of carrier.
5) Predicted to be durable for a minimum of 100 years in natural soil with a pH between 4 and 9 and at a soil
temperature 5 25`C.
6)100%of original tensile strength retained following exposure to intense UV radiation and accelerated weathering in
accordance with EN 12224.
