Calgary retaining walls
Retaining walls that make difficult grades usable
A retaining wall is both a site solution and a visible landscape feature. Picasso approaches wall work through grade, water movement, access, material choice, and how the wall connects to the rest of the property.

Hardscape & Site Work · in motion
The whole property shapes retaining walls.
The visible result begins with the site: how people move through it, how materials meet, how water travels, and how the landscape will be used through Calgary’s seasons.

Where this service helps
Start with the property problem, not a generic package.
Retaining walls are often the difference between a backyard that fights the site and one that works with it. Picasso treats them as both a technical solution and a visual feature.

Service planning detail
How Picasso scopes this work.
Materials
- • The approved system may use segmental concrete wall units or suitable natural stone with granular base, drainage aggregate, geotextile, drain components, caps, and professionally specified reinforcement.
Methods
- • Review grades, loads, utilities, drainage, access, and approvals; construct the prepared base and drainage; install wall courses; backfill and compact in controlled stages; and finish adjacent grades.
Timeline drivers
- • Investigation, engineering or permits, demolition, excavation, disposal, drainage correction, material lead times, weather, soil conditions, and inspections.
Technical considerations
- • Wall height, slopes, surcharge, boundaries, nearby structures, and current requirements may require an engineer or another qualified specialist.
- • Freeze-thaw cycles, moisture-sensitive soils, snowmelt, drainage outlets, nearby foundations, and winter loading must be considered for the specific site.
What the scope can include
A clear outcome before crews and materials move.
Scope planning
Questions the project scope should resolve.
- 01Review grade and visible site conditions
- 02Confirm wall purpose and material direction
- 03Identify engineering or permit questions before work
- 04Prepare, install, drain, and finish adjacent areas
Built for Calgary conditions
Local details belong in the scope.
- Freeze-thaw movement and base depth
- Subsurface drainage and surface water
- Property lines, utilities, and access
- Permit or engineering review where the project requires it
Common questions
What homeowners usually want to know.
Does every retaining wall need a permit?
Requirements depend on height, location, loading, and site conditions. Picasso will identify when the homeowner should confirm requirements with the City or a qualified professional.
Can an old wall be replaced?
Yes, after the existing conditions, access, drainage, and reason for failure have been reviewed.
Can a wall create more usable space?
Often it can define flatter lawn, planting, patio, or circulation zones, depending on the property and approved design.
