Interlocking and block walls people actually search for
This is the wall most Langley homeowners type into Google. Interlocking retaining wall. Segmental block. Concrete block wall. It's the manufactured units with a lip that stack into a clean face. Done right, it's one of the best residential systems you can buy. Done wrong, it's a kit leaning over a flower bed.
We build both engineered segmental walls and reinforced masonry block. Same idea: a level pad, units that interlock, steel or geogrid when the height needs it, and a drain that actually outlets.
Why these walls fail so often
Because they're easy to start and easy to cheap out on. Crews skip the compacted lifts, skip the grid, and dump native clay back behind the face. The wall looks finished on Friday. By the third wet winter the belly shows.
Langley's clay is unforgiving here. If the backfill can't drain, interlocking block becomes a dam. We rebuild a lot of these. The units are often reusable. The base and the drain are not.
When interlocking block is the smart choice
Taller backyard retains. New-build grades in Willoughby. Modern houses that want a straight, even face. Walls that need an engineer's stamp. Block is faster than hand-laid stone and it takes height when the design is right.
It's also a good hidden structure. We can build the retain in block and face the parts you see with stone or brick. Strength where you need it, character where you look.
What a proper block install includes
Excavation, a compacted leveling pad, the first course dead level, geogrid at the designed heights, free-draining backfill in lifts, weeping tile, fabric, and an outlet. Caps get adhesive. Compaction happens in layers, not with a shrug at the end.
If your quote from someone else doesn't mention those things, you're not comparing the same wall. Forge Langley Retaining Wall Contractors prices the wall that lasts, not the wall that photographs well on day one.
