DuraHold & DuraHold 2
Solid concrete blocks stack up and last forever. DuraHold is a robust system routinely used in areas likely to be submerged under quick flowing water with rapid drawdown. In one instance, it was installed by a Faddis customer at a Pennsylvania Department of Transportation (PennDOT) maintenance yard to replace a worn out railroad tie wall. A blast barricade was then erected using Durahold II blocks with alternate courses reversed to construct a vertical 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 where 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 designs and pricing, in place. Design is contingent on 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
