Compacting the wall rock behind your retaining wall, as well
as inside the cores of the facing units is key.
Allan Block recommends that a hand operated plate compactor
be used behind the base course within the 3 ft (0.9 m) wide consolidation zone
with a minimum of two passes.

Final compaction requirements are typically 95% of Standard
Proctor.For more information, see Sec. 1 Part 3.4 E in the Allan
Block Spec Book. (ref. BP, Chapter 6.7)
Allan Block is working to achieve our industry initiative of Zero Wall Failures. With our Best Practices Manual and experience in the industry we are trying to expand the knowledge base for the design of segmental retaining walls (SRW's) by communicating and educating the professionals in the industry.
