Backfill Material: Use well-draining backfill material, such as gravel or crushed stone, behind the retaining wall. Avoid using compacted soil that could hinder water movement.
Weep Holes: Incorporate weep holes or drainage pipes at the base of the wall to allow water to escape. These openings should be designed to prevent clogging while facilitating water drainage.
Thanks and regards
