Hardscaping in Calgary: patios, pavers, steps, and retaining walls that last

Hardscaping in Calgary: patios, pavers, steps, and retaining walls that last

Calgary winters punish shortcuts. If you want a patio or paver walkway that stays level, base prep and edge restraint are everything.

Freeze/thaw-ready hardscape principles

• Excavation to proper depth (varies by application and soil)

• Correct base aggregate (well-graded)

• Proper compaction in lifts

• Bedding layer done right

• Edge restraint that doesn’t move

• Thoughtful slope for drainage (don’t trap water against the house)

Retaining walls: permits and rules you can’t ignore

In Calgary:

• Retaining walls 1.2 m (4’) or greater generally require a development permit.

• The City also notes retaining walls must be less than 1.2 m in certain contexts (measured from the lowest adjacent grade to the highest retained grade).

If you’re building anything tall, tiered, supporting loads (driveways), or near property lines—assume you’ll need proper approvals and possibly engineering.
