DuraHold & DuraHold 2
Solid concrete blocks stack up and last forever. DuraHold is a proven system that is so strong and robust that it is routinely selected for use where it is likely to be submerged under rapidly flowing water with rapid drawdown. It was installed at a PennDOT maintenance yard to replace a wornout railroad tie wall. A blast barricade was erected using Durahold II blocks, with alternate courses reversed to construct a verticle face. Each Durahold unit is 12 inches tall, 24 inches deep and 72 inches long. Durahold II is half the depth per block. For low height walls, it is a gravity system to be used were there is no space for a cribbed system. For taller walls, tie-back units either one or two deep create a crib that is backfilled with crushed stone resulting in a massive free draining construction.

Dura-Sales can provide DuraHold designs and pricing, in place. Design is dependent upon local site conditions. For design, provide length and height of wall, backslope conditions - level ground, slope angle, or surcharge, and the phi angle of the material to be retained for use in the design of the wall system.
