Install Wall Rock and Backfill Materials Fill the hollow cores and a minimum of 12 in. (300 mm) behind the wall with wall rock. Use approved soils to backfill behind the wall rock and in front of the base course. Use a plate compactor to consolidate the area behind the blocks. Compact in lifts of 8 in. ( 200 mm) or less.

Base Material Round rocks such as pea gravel rolls and dislodge under pressure resulting in failure of the retaining wall. Lay a 4-6 inch layer of the crushed base material in the trench. Next compact it and level it using either a hand or mechanical compactor.Subsequently, question is, should you glue retaining wall blocks? Seasonal movement can be substantial. At 6 blocks tall, I would not recommend masonry adhesive. Adhesive is fine for caps or just a couple of courses, but six interlocking courses should have mortar and possibly vertical re-bar if you want it to last more than a season or two. Consequently, do you fill hollow retaining wall blocks? Fill in the area in front of the blocks with on-site soils. This will keep the base course blocks from shifting while filling and compacting. Fill the hollow cores of the base course and 12 in. (300 mm) behind the block with wall rock to the height of the block.How deep do you have to dig for a retaining wall?Begin digging into the ground with a shovel. Depending on the size of your blocks, your trench should be 4 to 6 inches deep (below ground level) and have a width that’s twice the width of one block lying vertically. Once your trench is complete, compact it with a hand tamper or vibrating plate compactor.
