Retaining walls in Ottawa

A retaining wall holds soil where ground levels change. It can help create level areas or separate spaces at different heights. Its design needs to account for the soil, water and loads around it.

Options include segmental concrete blocks, natural stone and poured concrete. Suitability depends on the wall height, site conditions, drainage needs and the design requirements of the chosen wall system.

The starting point is the difference between existing and proposed ground levels. Slopes, nearby buildings, driveways and other loads also affect the design. These factors help determine whether professional engineering is needed.

Water that builds up behind a wall can increase pressure on it and contribute to movement. Drainage needs to be considered alongside the soil, backfill and a suitable discharge location. The details depend on the site and wall system.

Requirements depend on the wall and its location. Check current permit and approval requirements with the City of Ottawa before work begins. Ask whether engineering, zoning rules or conservation authority requirements apply to your property.

Steps can connect spaces at different levels, and some walls can be designed to include seating. These features affect the layout and loads on the wall. Step dimensions, safe access and any required guards need to be considered as part of the design.

Gather photos of the area and note the grade change, approximate dimensions, access points and any visible water issues. Describe how you want to use the space and whether the work involves a new wall or an existing one. Property surveys or plans can also be useful if available.
