When does a retaining wall need a permit?

Requirements vary by municipality. Most cities require permits for walls over 1.2m, but some (like Maple Ridge) require them at just 0.6m. Walls over 1.0-1.2m typically need structural engineering. We research your city's specific thresholds before starting.

How long do retaining walls last?

A properly built concrete block or poured concrete retaining wall lasts 50-100 years. The key factors are drainage behind the wall, proper compaction, and adequate footing depth. Wood retaining walls typically fail within 10-15 years.

What causes retaining walls to fail?

The #1 cause is poor drainage — water builds hydrostatic pressure behind the wall and pushes it over. Other causes include inadequate footings, poor compaction, and walls built taller than their design allows. We engineer drainage into every wall with weeping tile and gravel backfill.

Retaining Wall Contractors — Poured Concrete & Timber Walls

Retaining walls are structural elements that hold back earth and create usable space on sloped properties. Getting them wrong leads to catastrophic failure — that's not hyperbole. We build poured concrete and timber retaining walls with proper engineering, drainage, and geotechnical assessment. From standard gravity walls to radius curves and multi-tier terraces, every wall is designed for the specific soil conditions and load requirements of your site.
