Retaining Wall Construction
Natural stone, interlocking block, and timber retaining walls. Engineered for Ontario conditions, designed to transform your property.
A retaining wall does two things: it holds back earth, and it creates usable space where there was none. If your yard slopes sharply, if your garden beds wash out every spring, or if you want to carve out level terraces for a patio or garden, a retaining wall is the answer. We design and build retaining walls across the Greater Toronto Area using natural stone, interlocking block, and timber.
Ontario is hard on retaining walls. The freeze-thaw cycle heaves soil and puts enormous pressure on any structure in the ground. That is why we build every wall with proper drainage behind it — gravel backfill, weeping tile, and filter fabric to let water escape instead of building up pressure. The footing goes below the frost line, and the base is compacted properly. These are not shortcuts you can see, but they are the difference between a wall that lasts 30 years and one that leans after two winters.
We work with homeowners to choose the right material for the job. Armour stone and natural limestone walls have a timeless look and incredible durability. Interlocking block systems are engineered for structural walls and come in a range of styles. Timber walls work well for garden terracing and lower-height applications. Every project starts with a site visit, and we handle permits when they are required.
Retaining Wall Services
Natural Stone Walls
Armour stone, limestone, and fieldstone retaining walls that look like they belong on your property. Built to last through decades of Ontario freeze-thaw cycles.
Interlocking Block Walls
Engineered retaining wall blocks for clean lines and consistent strength. Available in a range of colours and textures to match your home and landscape.
Timber Retaining Walls
Pressure-treated timber walls for a natural, rustic look. Best suited for low-height applications and garden terracing.
Drainage Systems
Proper drainage behind every wall — gravel backfill, weeping tile, and drainage fabric to prevent hydrostatic pressure buildup that causes wall failure.
Slope Management
Terracing steep yards into usable, level spaces. We engineer multi-tier retaining wall systems that turn problem slopes into functional outdoor areas.
Permits & Engineering
Walls over a certain height require permits and may need an engineer's stamp. We handle the process and make sure everything is built to Ontario Building Code standards.
Our Retaining Wall Process
Site Visit & Design
We assess your slope, soil conditions, and drainage. Then we design the wall system and present material options with a detailed quote.
Permits & Prep
We pull permits if required, excavate the site, and prepare a properly compacted base with drainage infrastructure.
Build & Finish
The wall is built to spec, backfilled with drainage gravel, and finished with grading and cleanup. We walk you through the completed project.
