Retaining Walls
Engineered retaining walls that solve real drainage problems while adding stunning visual depth and dimension to your landscape — built to hold for decades.
Engineered retaining walls that solve real drainage problems while adding stunning visual depth and dimension to your landscape — built to hold for decades.
A retaining wall isn't just a visual feature — it's a structural element that manages soil, controls water flow, and protects your property. At Rundle Landscaping, we engineer walls that are both functional and stunning, designed to handle Calgary's unique soil conditions and extreme weather.
Whether you're dealing with a sloped yard, drainage issues, or you simply want to create dramatic elevation changes and usable terraced areas, our experienced crew has the knowledge and equipment to deliver walls that stand the test of time.
Proper excavation, compacted gravel foundations, and geogrid reinforcement where required. We build walls that are structurally sound from the ground up.
Every wall includes proper drainage behind it — weeping tile, drainage gravel, and filter fabric to prevent hydrostatic pressure buildup.
Allan Block systems, natural stone, boulders, and treated timbers — chosen for your specific application and aesthetic preferences.
In Calgary, retaining walls over 1.2 metres (4 feet) in height typically require a development permit, and those exceeding certain heights may need an engineer's stamp. We know the rules and will advise you during the estimate process — and handle permitting when needed.
The #1 cause of retaining wall failure is poor drainage. Water builds up behind the wall creating hydrostatic pressure that pushes it outward. That's why every wall we build includes a drainage system behind it. The #2 cause is inadequate base preparation — which is why we never skip steps.
A properly built retaining wall with adequate drainage and a proper base can last 50+ years. Our Allan Block and natural stone walls are engineered to withstand decades of Calgary's freeze-thaw cycles, backed by our 3-year hardscape warranty.
Absolutely. Multi-tiered walls are one of our specialties. They transform steep slopes into beautiful, usable terraced areas — perfect for garden beds, seating areas, or level lawn sections. The engineering gets more complex with height, but that's where our 20+ years of experience shines.
"Our backyard had a major slope problem and Rundle built a gorgeous multi-level retaining wall system that completely transformed the space. We now have three usable tiers where we used to have an unusable hill. Incredible work."
"We needed a wall to solve a serious drainage issue that was threatening our foundation. Colin's team didn't just build a wall — they fixed the root cause of the problem. Professional, knowledgeable, and done right the first time."
Whether it's solving drainage, creating usable space, or adding stunning visual layers — let's start with a free on-site assessment.
