Interlock and yard drainage in Barrhaven
Korvex builds interlock patios, drainage, fences and decks across Barrhaven. The ground is part of the Ottawa Valley clay plain, with clay roughly 8 to 10 m deep along the Jock River. Clay drains slowly, so on a flat lot every post, footing and patio base starts with getting water off the yard.
Barrhaven began in the 1960s south of the Greenbelt and had grown to about 103,000 people by 2021. The Rideau River forms its eastern edge and the Jock River runs through its south, with communities from Old Barrhaven and Longfields to Stonebridge and, south of the river, Half Moon Bay.

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.
- Deep clay plain
Along the Jock River the clay layer runs about 8 to 10 m deep over limestone and dolostone. Base thickness, compaction and slope are set for that soil.
What it changesinterlock, retaining walls, backyard renovations
- Jock River floodplain
The Jock River through south Barrhaven has a mapped 100-year floodplain, and part of it north of the river was cut and filled in 2019–2020 for a new subdivision.
What it changesdrainage & grading, retaining walls
- First streets and new phases
The first subdivision houses along Larkin Drive date to the late 1960s and early 1970s, while Half Moon Bay is one of the newer areas. Older yards come with existing structures to remove, newer ones with a recent grading plan to follow.

Do you work in all parts of Barrhaven?
Yes. Korvex Developments builds interlock, drainage, fences and decks across Barrhaven, including Old Barrhaven, Longfields, Chapman Mills, Stonebridge and Half Moon Bay. One of our Barrhaven jobs is on this page: a front garden bed rebuilt with landscape fabric, mulch and a clean paver edge. Request a free estimate or call 613-880-7679.
My backyard is near the Jock River. Do I need extra approval?
Possibly. On regulated land along the Jock River, grading, fill and structures can need a Rideau Valley Conservation Authority permit on top of City of Ottawa rules. Its online map shows whether a lot is regulated, and we check what applies to yours before planning the work.
Why does water sit on my lawn after rain?
Barrhaven sits on clay, which drains slowly, and a yard that has lost its slope holds water near the surface. City of Ottawa guidance asks residents to call 3-1-1 if water is still there after 48 hours. We look at slope, swales and downspouts and check what applies to your property before proposing a fix.
Are your estimates free?
Yes. Korvex Developments 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.
Who arranges utility locates before digging?
The person doing the digging requests them through Ontario One Call, at least five business days ahead, and the locates are free. Private lines, such as a gas line to a barbecue, power to a shed or a septic system, are the owner’s to have marked, so tell us about them at the site visit.
Who will I deal with?
One Korvex project lead, from the site visit and the written estimate to the final walkthrough. The same person answers the phone and walks the finished job with you, and the crew that builds it works together on site.
Can I see your work?
Yes. Every project on this site is a Korvex job in the Ottawa area, photographed on site while it was built, many with the base and drainage still open. The reviews page quotes homeowners word for word from Google, HomeStars and Facebook.
Will I get a written contract?
Yes. Korvex gives you the scope and the price in writing before work starts. Ontario law also requires any home renovation contract worth more than $50 to be in writing, and a contract signed in your home comes with a 10-day cooling-off period.
