Soil excavated a minimum of 8”. Base layer of 4” of CA-7(3/4” clean limestone) compacted in 2” increments, and 1” of turkey grit bedding is installed below the pavers. Pavers are then compacted with a plate compactor and polymeric sand is swept int the joints. Polymeric sand is then activated by water.
Footing soil is excavated a minimum of 12” and 6” base footing of CA-7(3/4” clean limestone) compacted every 2’” and first row of blocks are installed below soil grade. Soil is also excavated the appropriate amount behind the wall according to manufacturer’s specs, 4” perforated drainpipe, geo-grid (if necessary) and CA-7(clean rock-no fines) backfill are installed to allow for proper water drainage and to relieve hydrologic pressure on the wall. The amount of excavation and drainage needed is directly co-related to the height of the wall.
