Strength runs along the ribs. The brochure highlights tensile capacity in that direction, creep resistance, chemical stability, and friction against sand and stone.
For a reinforced-soil wall it describes a precast concrete face, with the main strength direction set perpendicular to the face. Pavement use is described in the same terms as the biaxial grid.
What the brochure emphasises
- High tensile strength in one direction.
- Creep resistance and chemical stability, as stated.
- High friction with sand and aggregate, as stated.
Uses named in the brochure
- Embankments, tunnels, quays, highways, railways and building works.
- Reinforced-soil retaining walls.
- Subgrades and pavement layers.
Laying notes printed in the brochure
These are the manufacturer’s notes. They do not replace the project specification or the engineer’s method statement.
- Facing panels in the brochure are generally 12–15 cm thick, on a precast footing no wider than 30 cm, no thinner than 20 cm, and buried at least 60 cm.
- Level and compact the foundation. Soft soil is compacted or replaced. Work slightly beyond the face line.
- Lay the main strength direction perpendicular to the face and pin it.
- Place fill by machine. Keep wheels at least 15 cm off the reinforcement. A compacted lift is described as about 15–20 cm.
- Wrap the face with geotextile so fill does not leak through.
Stated in the brochure
- The brochure prints percentage savings and crack-delay claims for pavement use. They are not tied to a grade or a test report, so they are not repeated here.
