In the south rear of building owner would like to connect to retaining walls 26 feet apart. Maximum height 7 feet. The same retaining wall block wall be used that is currently installed on existing walls. Rockwood classic 8 wall straight face charcoal 8 in. X 18 in. X 12 in. Beginning at a point of the wall’s lowest elevation excavate a trench down the length of the wall that will accommodate at least 6 of base material and 6 of block embedment. As a rule of thumb for every 8 to 10 of wall height 1 of block should be buried with at least a minimum of 6 base course embedment. Step the trench up or down with respect to adjacent grade. The width of the trench for a classic wall should be a minimum of 24 while the trench width for a legend® wall should be a minimum of 34 after excavating the native soil and prior to adding base material remove loose material from the trench and compact. Place and compact a minimum of 6 base material to 95% standard proctor. Verify that the base is level with a transit or hand level. Use a string line behind the tail of the block for alignment on straight wall applications. All blocks should rest firmly on the pad and be centered to allow 6 of base material in front and 6 behind the base block. Level each block side-to-side front-to-back and across three full blocks with a hand level. A ded-blow hammer may be used to level and align the blocks place 3/4 to 1 clean aggregate (crushed rock) within the cores and a minimum of 12 behind the blocks. Place the backfill material behind the drainage rock in maximum of 8 lifts and compact to 95% standard proctor. Repeat this process for each successive course
