Lock-block retaining walls are a durable, modular wall system built from interlocking concrete blocks designed to handle soil pressure and grade changes. They’re a popular choice for Vancouver Island properties because they offer a clean, modern look and can be engineered to suit everything from small garden walls to larger structural walls.
A properly built lock-block wall starts with the fundamentals: correct excavation depth, a compacted gravel base, proper drainage behind the wall, and clean alignment. When installed right, lock-block walls provide long-term stability, resist shifting, and create usable, level space where a sloped yard would otherwise be wasted.
Great for:
Sloped yards and terraced landscaping
Creating level lawn or patio areas
Replacing failing timber walls
Garden bed borders and structural grade separation
Common options & upgrades:
Straight or curved wall layouts
Tiered/terraced wall systems
Integrated stairs and landings
Cap stones for a finished top edge
Drainage integration (drain rock, fabric, weeping tile as required)
