Why Retaining Walls Are Essential for Ottawa Properties

Sloped lots are common across Ottawa’s older and newer subdivisions alike, and unmanaged slopes often get worse over time. Soil erodes with every heavy rain; mulch and topsoil wash downhill, and any grass on the slope becomes nearly impossible to mow safely – a common driver behind the landscape drainage Ottawa property owners request. A properly engineered retaining wall stops that erosion and creates flat, usable terraces where there used to be a hard-to-manage grade.

There’s a structural side too. Retaining walls near an interlock driveway that Ottawa homeowners have installed at the foundation or property line manage soil pressure that would otherwise shift over time, especially through Ottawa’s freeze-thaw winters, when saturated soil expands and contracts.

Why Choose Bennett Lawn & Landscape as Your Retaining Wall Contractors in Ottawa

Isaac Bennett is on site for every retaining wall project. The crew that starts your build is the same crew that finishes it, no subcontractors handing the job off partway through. We’re listed on the City of Ottawa’s Hardscape Licensed Contractors registry, carry WSIB coverage, and are a Landscape Ontario member.

We won’t cut corners on drainage behind a wall to save a day of labour. A retaining wall built without proper drainage is the most common reason we get called to fix someone else’s work a few years later. It’s also why homeowners increasingly ask specifically for retaining wall contractors who handle the drainage step rather than skip it.

When you’re comparing retaining wall contractors in Ottawa, ask about base depth and drainage before you ask about stone colour. Those two details decide whether the wall is still standing straight in ten years – it’s the standard we hold every project to at Bennett Lawn & Landscape.

 Trustindex verifies that the original source of the review is Google. We recently hired Bennett Landsaping to update areas of our backyard.  We were extremely impressed with Issac and his crew! The job was completed on time and on budget. The level of communication was excellent, and Isaac and his  crew had some great suggestions that we were excited to incorporate into our original plan. Our property was left clean and free of any left over material and debis. Issac and his crew installed a beautiful firepit with a semi circular bench,  a water feature and walkway, which turned out beautiful.  We would not hesitate to recommend Bennett Landscaping, and would definitely use them in the future. Thanks Issac, Gibby and Remi for a job well done!

 Trustindex verifies that the original source of the review is Google. A big thank you to Isaac and his team for finishing our patio to a very high standard, on time and on budget. This is a very skilled, organized and efficient operation.  Isaac and his team are straightforward, flexible and pleasant to work with.  He gave us the 5 star treatment so I give Bennet Landscaping a 5 star rating in return. Our neighbours had already reached out to him for work on their properties even before he had finished with ours. We look forward to the next project. Totally recommend.

Frequently Asked Questions

What materials do you use for retaining wall installation in Ottawa?

Most of our builds come down to two materials: interlocking concrete block and natural armour stone. Wall height, the visual style you want, and how it needs to fit with the surrounding landscape all shape which one we suggest.

How long does a retaining wall installation take?

A few days to a week is the typical range for residential jobs. Wall length and height matter, but so do the excavation and drainage work the site requires.

How much does a retaining wall cost in Ottawa?

There’s no single number. Height, length, material, and site access all affect the price. Our Price Guide walks through the general factors, and once we’ve seen your property, we’ll give you exact figures.

Do retaining walls require permits in Ottawa?

Often, yes. Once a wall passes a certain height, Ottawa generally requires a permit for it. We’ll flag whether that applies to your project during the quote visit and walk you through what’s needed.

How do retaining walls prevent soil erosion?

A retaining wall holds soil in place on a slope so it doesn’t erode during rainfall, which in turn opens up the terraced ground behind it for planting or grading.

How long do retaining walls last in Ottawa's climate?

A properly built retaining wall, with a compacted base and drainage behind it, can last decades even through repeated freeze-thaw cycles. Most failures we see come from walls that skipped that base and drainage work in the first place.
