Most retaining walls bow, tip, and fail within 10 years. Ours don't.
Shifting soil and deep frost destroy poorly built walls fast. We engineer every footing depth, batter angle, and drainage layer for GTA ground conditions — so your wall stands solid for 30+ years.
Unmanaged slopes and water runoff silently destroy yards, foundations, and landscaping. Our walls redirect hydrostatic pressure and protect your property from the inside out.
Steep grades and eroding banks become flat, functional areas — patios, garden beds, driveways, or lawn space. More usable yard means more liveable home and higher resale value.
Ignoring a shifting slope or a failing wall isn't just an eyesore; it's a structural liability that threatens your home's foundation and property value.
Every spring thaw and heavy rain carries away valuable topsoil, destroying gardens and leaving ugly, muddy washouts.
A bulging or leaning wall can collapse at any time. When it holds back tons of earth, failure is catastrophic and expensive to clean up.
Poor drainage behind failing walls forces water to pool against your home's foundation, leading to damp basements and severe structural cracking.
A properly engineered retaining wall from Unicorn Landscaping solves all of this — permanently.
Most landscapers "stack" walls. We engineer earth-retention systems. There is a catastrophic difference.
Continuous clear stone backfill and perforated weeping tile are standard on every build to prevent wall-destroying water pressure.
We dig bases below the frost line with proper geogrid soil reinforcement to ensure zero shifting during Ontario's winter freeze-thaw cycles.
If your wall leans, bows, or tips within 5 years, we fix it for free. Our engineering is backed by a legally binding project warranty.
Dirt backfill traps water behind the wall, creating pressure that causes bowing and eventual collapse.
Bases dug just a few inches deep will heave and tip as soon as the first deep frost hits.
Warranty expires the moment their truck leaves your driveway. Good luck getting them back to fix a leaning wall.
We don't just stack stones. We engineer earth-retention systems designed to withstand Ontario's freeze-thaw cycles for decades.
A beautiful wall means nothing if it leans after one winter. We utilize proper geogrid soil reinforcement, compacted granular bases, and commercial-grade drainage systems to relieve hydrostatic pressure — the #1 cause of wall failure in Ontario.
Stop paying taxes on a slope you can't use. A terraced retaining wall system carves flat, usable square footage out of steep hillsides, transforming dead zones into stunning outdoor living spaces.
We source premium materials from Ontario's top quarries and manufacturers. Each wall is custom-matched to your home's exterior and architectural style.
Modern, clean lines and uniform appearance. The most popular and cost-effective choice for contemporary properties.
Timeless, rustic elegance with unique character in every piece. Hand-chiseled and fitted for a truly bespoke landscape.
Massive, dramatic limestone blocks ideal for large-scale earth retention and creating commanding focal points.
Precision interlocking craftsmanship across the Greater Toronto Area.
Precision is everything. We follow a strict 5-step protocol to ensure your wall complies with Ontario Building Codes and lasts a lifetime.
Evaluating soil composition, water runoff patterns, and slope grade to determine engineering needs.
Selecting materials and drafting structural plans, acquiring necessary municipal permits if required.
Digging the crucial foundation trench below the frost line and installing the primary drainage system.
Stacking blocks with geogrid tie-backs and continuous clear stone backfilling to prevent hydrostatic pressure.
Capping the wall, restoring topsoil, and ensuring all surface water is directed away from the structure.
Timeline: Most retaining walls are completed in 5–14 days depending on scope.
"Unicorn Landscaping transformed our dangerous, eroding slope into a stunning tiered stone wall system. The engineering was impressive—deep footings and proper drainage mean I finally have peace of mind. It’s not just a wall; it’s a massive upgrade to our property value."
"The structural work they put in was incredible. They explained the drainage layers and geogrid reinforcement so I knew this wall wasn't going to budge in the winter. Professional from start to finish."
"Our backyard was unusable because of the steep hill. Now we have two beautiful level tiers for garden beds and a patio. Total professionals who actually understand structural masonry."
"We've had walls fail in the past because they were just 'stacked'. These guys engineered it properly. Seeing the finished armour stone is a dream. A structural solution that looks like art."
