Welded Wire Wall
Welded Wire Wall is adaptable to a variety of site conditions. Welded wire mats are used to reinforce the soil, providing the tensile strength to make the compacted soil into a stable structure.

The face of the wall may be either battered or vertical and may be left exposed, vegetated, or covered with a poured concrete or blown mortar (gunite) skin.

Why Steel Reinforcements?

Steel reinforcements for MSE walls are either welded wire mats (used by Hilfiker Retaining Walls and T&B Structural Systems) or ribbed strips (used by The Reinforced Earth Company). Steel reinforcements offer the following advantages over other MSE reinforcement systems:

  • Inextensible. Steel reinforcements undergo very low strains when loaded, so there is negligible structure deformation due to reinforcement elongation.

  • High Adherence. Steel reinforcements embedded in specified granular backfill do not pull out, assuring internal structural stability.

  • Tensile Capacity. Steel reinforcements have high strength, which is well suited to MSE structures in a wide range of heights and loadings.

  • Long Service Life. Steel reinforcements are galvanized with 2 oz of zinc per sq ft of metal surface (ASTM A-123), helping them achieve a long service life. When embedded in backfill conforming to AASHTO requirements for pH, resistivity, chlorides and sulfates, the reinforcements can be designed to meet AASHTO’s permanent MSE wall 75-year service life requirement (100 years for critical structures like bridge abutments).

  • Economical. Steel reinforcements attached to precast concrete MSE wall panels are straightforward to install using simple connection devices cast into the panels. Only modest construction equipment and a small labor crew are necessary for wall erection. The required granular backfill is easy to place and compact and the more free-draining backfills can be placed almost regardless of weather, enhancing productivity and economy.
