This report presents the results of a HITEC evaluation of the Isogrid Retaining Wall System, designed and developed by the Neel Company. The report describes the basic capabilities and limitations of the Isogrid System for use as a technically viable precast, mechanically stabilized earth retaining wall system. The evaluation was conducted based on material, design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The Isogrid System features a diamond-shaped, segmental precast concrete facing panel with weep holes where four panels intersect and welded wire, grid-type soil reinforcement attached to the center of each facing panel.
