Yes. Hydrostatic pressure from water buildup behind a wall is the leading cause of collapse. Using specialized block drains and gravel backfill is essential to divert water away from the structure.
For most DIY segmental walls, a high-quality landscape block adhesive is preferred over mortar. It provides a strong, flexible bond that accommodates slight ground shifts without cracking.
