Fences, interlock and decks in Stittsville
Korvex builds fences, interlock patios, decks and drainage across Stittsville. Around Poole Creek the mapped ground is mostly bedrock and organic deposits, with little clay, so one new yard can have shallow rock in one corner and soft, wet ground in another. Base depth and drainage are settled before the fence or patio goes in.
Stittsville started as Stitt’s Corners, at what is now Carp Road and Hazeldean Road. Water and sewer service approved in the 1970s opened it to growth, and about 44% of its homes have been built since 2016, in areas like Fairwinds, Hartsmere and the Fernbank area.
What we plan around in Stittsville
The ground, the lots and the local rules
Each point links to the public source it was checked against. At the site visit we check how it applies to your lot.
- New homes, recent grading plans
Nearly half of Stittsville’s homes are less than ten years old, so many lots still follow their original grading plan. The City expects owners to keep those grades and leave swales open.
What it changesdrainage & grading, interlock, backyard renovations
- Shallow bedrock
About 37% of the Poole Creek catchment is mapped as bedrock at the surface. Post holes and footings can meet rock at shallow depth.
- Wetland and organic soils
Almost a third of the same area is organic deposits, the soft wet ground around the Goulbourn Wetland. Soft spots under patios and walls are dug out and replaced with compacted granular base.
What it changesinterlock, retaining walls, exterior waterproofing
- Creek banks and runoff
Surveys found moderate bank erosion along parts of Poole Creek, including stretches in residential areas. Yards near the creek corridor keep runoff directed away from the slope.

Retaining walls in Stittsville
Segmental block on a compacted base, with drainage behind
Korvex Construction builds segmental block retaining walls in Stittsville, together with the interlock patios, block steps and complete backyards they usually connect to. Each wall is planned with the lot’s grading and drainage, which the free on-site estimate looks at before a written price is prepared. Send a photo of the slope with the request form, or call 613-880-7679.
Retaining wall block is a concrete unit that stacks without mortar and steps back slightly as the wall rises. The wall stays in line thanks to the compacted base under the first course and the drainage stone and pipe behind it, which keep water from building up and pushing when it freezes.
On a newer Stittsville lot, a wall usually sits where a raised patio, the lawn and a neighbour’s yard meet, which is also where the grading plan sends water. The City treats any change that harms a lot’s intended drainage as a breach of its site alteration by-law, and swales are not to be filled, piped or blocked by landscaping. A wall is laid out so the swale stays open.
When a wall needs a permit or an engineer
The City’s rules for landscape structures
City of Ottawa Building Code Services has an advisory for structures built from landscape materials such as stone, concrete and interlocking block. It sets out when a wall, steps or a landing needs a building permit:
- when it gives access to the house and the surfaces on either side differ by more than 600 mm, with a guard where the Code requires one;
- when it is over 1 m high, which calls for an engineered (Part 4) design;
- when it is attached to the foundation, which needs a professional engineer’s design in every case.
- Walls that tier a yard into flat areas, without touching access to the house, are reviewed case by case.
Near Poole Creek and the Goulbourn Wetland
Mississippi Valley Conservation Authority rules
Parts of Stittsville fall under the Mississippi Valley Conservation Authority. Inside its regulated area, new structures, additions, site grading and the placing or removal of fill need an MVCA permit. Its rules cover hydrologically connected wetlands over 0.5 ha and land within 30 m of them, plus flood plains with a 15 m Regulation Limit.
The MVCA calls its online map a general guideline that may miss a regulated feature, and it lists the order of approvals: any Planning Act approval first, then the MVCA permit, then the City building permit. For a wall, a patio or regrading near the creek, we check the map and the rules for your lot before the design is fixed.

What retaining wall blocks do you use?
Our block work is segmental concrete block: interlocking units that stack without mortar and step back as the wall rises. The same block builds garden walls, steps and landings, so the levels line up; ask about other materials at the site visit.
Does a retaining wall in my Stittsville backyard need a permit?
It depends on its height and what it does. A wall that gives access to the house needs a permit where the surfaces beside it differ by more than 600 mm, and any landscape structure over 1 m needs an engineered design. Garden walls that only tier the yard are reviewed case by case. Your wall’s case is checked before it is designed.
How do I know if the Mississippi Valley Conservation Authority regulates my lot?
The MVCA publishes a regulations map as a first guide and asks owners near a lake, stream, valley, wetland, pond or low-lying land to contact it as well, since the map may not show every feature. Grading, fill and structures in a regulated area need its permit before the City building permit.
Can the wall, the interlock patio and the steps be one job?
Yes. Walls built with block steps, interlock and landings are one of the ways we build them, so the levels connect and the drainage behind the wall is planned with the patio base. The written quote after the site visit covers all of it.
Do you work in Stittsville?
Yes. Korvex Construction builds fences, interlock, decks and drainage across Stittsville, from the streets near Stittsville Main Street to newer subdivisions like Fairwinds, Hartsmere and Fernbank. Many of these lots still follow their original grading plan, and the new work is set to keep it working. Request a free estimate or call 613-880-7679.
What happens if you hit rock digging fence posts?
We adjust how that post is anchored and tell you before changing the plan. About 37% of the Poole Creek catchment around Stittsville is mapped as bedrock at the surface, so a post or footing hole can meet rock at shallow depth.
Does a new pool or hot tub need a special fence?
Yes. City of Ottawa pool enclosure rules apply to pools, ponds and hot tubs that can hold 600 mm of water or more, and a permit is needed even when the yard is already fenced. We check what applies to your property before planning the fence.
Are your estimates free?
Yes. Korvex Construction gives free estimates on site across Ottawa and the surrounding areas. Send the request form, or call, text or WhatsApp 613-880-7679, and we book a time to look at the property. The scope and the price follow in writing after the visit.
What should I send with my request?
A few photos of the area, close up and from a few steps back, where the property is, and a sentence on what you want done. That is enough for Korvex to set up the site visit. Measurements, material choices and budget can wait for the visit.
Can the final price go over the estimate?
Ontario’s consumer rules for home renovations set a limit. When a contractor gives an estimate, the final price cannot be more than 10% over it unless you agree to new work or a new price. The rule covers every home renovation contract in Ontario.
