Retaining Walls Engineered to Hold. Designed to Impress.
Structural retaining walls built for BC's demanding soil and drainage conditions. Allan Block, Belgard, Unilock, and natural stone.
Retaining Walls That Solve Real Problems
A retaining wall is one of the most structurally demanding elements in any landscape. It holds back thousands of pounds of soil, manages water flow, and must withstand decades of freeze and thaw cycles, seismic activity, and root intrusion. In the Fraser Valley, where clay heavy soils expand and contract with the seasons and rainfall is measured in metres, engineering matters more than aesthetics alone.
At Trueform Hardscapes, every retaining wall begins with a full site assessment. We evaluate slope angle, soil composition, water table depth, surcharge loads from structures or vehicles above, and drainage patterns across the property. This data determines the wall design: base depth, setback angle, geogrid reinforcement spacing, and drainage provisions. We do not guess at these specifications because a wall that looks good but fails structurally is worse than no wall at all.
We install retaining walls using industry leading systems from Allan Block, Belgard, and Unilock, as well as natural stone and boulder walls where the design calls for it. Every wall includes proper excavation to engineered depth, compacted granular base material, perforated drainage pipe with filter fabric behind the wall face, and backfill to specification. Geogrid reinforcement is installed at calculated intervals for walls that exceed standard gravity limits.
Our installers are ICPI certified, meaning they have completed advanced training in segmental retaining wall design and installation. This certification matters because it means we follow the exact manufacturer specifications that activate the full product warranty. A wall installed outside of spec may look identical on the surface but will not carry the same structural guarantee.
Whether you need a small garden wall to create terraced planting beds, a structural wall to stabilize a hillside, or a combination retaining and seating wall for an outdoor living space, we engineer every project for your specific site conditions. The result is a retaining wall that performs as well in year twenty as it does on day one.
How We Work
Site Assessment
We evaluate your slope, soil conditions, drainage patterns, and load requirements to determine the right wall design.
Engineering & Design
Detailed wall design with material selection, base depth calculation, geogrid spacing, and drainage specifications.
Excavation & Base Prep
Proper excavation to engineered depth, compacted granular base, and levelling pad installation.
Installation & Backfill
Block or stone installation with drainage pipe, filter fabric, geogrid reinforcement, and compacted backfill at each course.
Premium Materials. Full Warranty.
Allan Block
Engineered pinned retaining wall system designed for structural walls up to 6 feet without geogrid. Rear lip provides automatic setback.
Belgard
Premium retaining wall units with natural stone textures and colors. Diamond Pro and Celtik systems for walls of any height.
Unilock
High density concrete wall units with industry leading compressive strength. Rivercrest and Pisa systems.
Natural Stone
BC quarried basalt, granite, and sandstone for dry stack or mortared walls with an organic, timeless look.
What to Expect
Retaining wall costs in the Fraser Valley typically range from $35 to $85 per square face foot installed, depending on height, material selection, site access, and whether engineering drawings or permits are required. A standard 3 foot gravity wall in Allan Block will be at the lower end, while a 6 foot geogrid reinforced wall with premium stone facing will be at the upper end. We provide a detailed, transparent estimate after our free onsite consultation.
Frequently Asked Questions
In most Fraser Valley municipalities, retaining walls under 4 feet (1.2 metres) can be built without engineered drawings. Walls over 4 feet typically require a structural engineer's stamp and a building permit. Trueform handles all permit applications and engineering coordination.
A properly engineered and installed retaining wall should last 50 years or more. The key factors are correct base preparation, proper drainage behind the wall, and using materials rated for our climate. All our installations carry full manufacturer warranty.
The most common causes of retaining wall failure are inadequate drainage behind the wall, insufficient base preparation, missing or improperly spaced geogrid reinforcement, and poor soil compaction during backfill. All of these are construction deficiencies, not material failures.
In Abbotsford, retaining walls over 1.2 metres (4 feet) require a building permit. Walls that retain a surcharge (driveway, structure, or slope above) may require a permit regardless of height. We confirm all permit requirements during your free consultation.
Yes. Steep slopes often require a tiered or terraced wall system rather than a single tall wall. This approach reduces the load on each individual wall, improves drainage, and creates usable planting terraces between wall levels.
Retaining wall costs typically range from $35 to $85 per square face foot installed, depending on height, materials, and site conditions. A typical residential wall project ranges from $8,000 to $35,000. Contact us for a onsite consultation.
