Ledge Block
The Corbel Ledge Block typically makes up 1-2% of the ICF wall assembly on most residential and commercial jobs. This block has six strong, full-length, injection molded plastic ties made from Polypropylene (PP) regrind resin that are well marked with the words “Fox Blocks” located on both sides of the block. These ties secure the two pieces of modified Expanded Polystyrene (EPS) foam together that makes up each block type. The blocks are stacked tightly together and inter-locked end to end to the desired wall length. Corbel Ledge Blocks are typically used at the top of the wall to support other adjacent lateral loads (i.e., masonry veneer loads, floor joist loads, etc.). Once a single layer or course of Corbel Ledge Blocks is installed, horizontal reinforcing steel bars are inter-locked securely together in the ties of the blocks, in the main core and the extended ledge core. The Fox Blocks xLerator reinforcement is designed to be placed in the top of the of Corbel Ledge Block to provide engineered reinforcement for the corbel. After the concrete is poured/cured, the Corbel Ledge Block can support a 25' tall masonry wall.
