Place filter fabric behind the first two units and extend it 2 feet along the existing structure. SECOND COURSE Build second course with standard installation techniques. A split unit is shown but may not be necessary in every installation. Extend filter fabric to the top edge of the final course. See Diagram 10 . A rubber membrane may be placed between the units and a non- concrete wall to prevent moisture damage to the structure.

Pound the chisel on the same line until the block splits. If partial unit sides are not exposed, use a saw with a diamond blade to achieve a tighter fit. Wall Filter Fabric
