Retaining Walls
Retaining walls that handle slopes, stop erosion, and create level areas in your yard. We use engineered block systems from Techo-Bloc, Unilock, and Permacon.
About Our Retaining Walls Service
If your yard has slopes or areas where soil washes away, a retaining wall is the fix. We build walls using engineered block systems from Techo-Bloc, Unilock, and Permacon that match your patio or walkway stones.
Walls over 2 feet tall need proper engineering. That means geogrid reinforcement, drainage behind the wall, and a compacted gravel base. We do all of that. We also install drainage tile to move water away from the wall, because water pressure behind a retaining wall is the number one reason they fail.
But retaining walls aren't just about holding back dirt. They also create space. You can turn a useless slope into level areas for gardens, seating, fire pits, or just more yard. Cap stones on top give a finished look and can double as seating.
Key Benefits
Why choose Oakville Fence Repair for your retaining walls needs.
Erosion & Slope Control
Retaining walls hold back soil on sloped properties, preventing washouts, lawn erosion, and foundation drainage problems that worsen over time if left unaddressed.
Usable Tiered Space
Turn an unusable slope into level terraces for gardens, seating areas, fire features, or play spaces. It's a real way to get more usable space out of your yard.
Seamless Hardscape Integration
We match wall block colours and textures to your patio or walkway stones, creating a unified hardscape design that looks intentional and professionally planned.
Engineered Drainage System
Every wall includes perforated drainage tile, filter fabric, and clear stone backfill to channel water away from the wall face and prevent hydrostatic pressure buildup.
Built-In Seating & Planters
Cap stones on retaining walls create natural seating ledges. Raised planter sections add greenery and soften the hardscape, blending function with beauty.
Retaining Walls FAQ
Common questions about our retaining walls services.
In Oakville, retaining walls over 1 metre (approximately 3.3 feet) in height typically require a building permit and engineered drawings. We handle the permit process and work with licensed engineers when required.
Single-tier residential retaining walls are commonly built up to 4 feet. Taller requirements are addressed with terraced (stepped) walls, which distribute soil pressure across multiple shorter walls and often look more attractive in a residential setting.
The most common causes are inadequate drainage (water pressure behind the wall), insufficient base preparation, and missing geogrid reinforcement. Our engineered approach addresses all three failure points to ensure long-term stability.
Yes. We frequently add retaining walls adjacent to existing patios to create raised garden beds, define seating areas, or manage grade transitions. Proper integration ensures the new wall doesn't undermine the existing patio base.
Properly engineered and installed retaining walls last 50+ years. The concrete block systems we use are rated for extreme freeze-thaw exposure and carry manufacturer warranties of 25 years or more on structural integrity.
