Yard drainage and interlock in Orleans
Korvex builds drainage, interlock, fences and decks across Orleans. A study of 73 sites found thick Champlain Sea clay under much of the suburb, with firmer ground around its edges, in places a thin layer of soil over bedrock. That clay holds water and moves with frost, so the work here depends on a deeper base and a slope that sends water away.
Orleans grew from about 6,000 people in 1971 to 24,000 ten years later, as farmland east of the city turned into suburban streets. Growth kept going, and the population passed 106,000 by 2010.
What we plan around in Orleans
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.
- Thick marine clay
Much of Orleans sits on thick, soft Champlain Sea clay, which loses strength when disturbed. Excavation stays tidy and the granular base is compacted in lifts.
What it changesinterlock, retaining walls, backyard renovations
- Firmer ground near the edges
Around the edges of Orleans and in a few central spots the ground is firmer, in places a thin layer of soil over bedrock. Two yards a few streets apart can need different footing plans.
- Yards from the 1970s boom
The first big wave of suburban streets went up in the 1970s, so the oldest yards are around fifty years old. Original patios, walls and fences there have been through many freeze and thaw cycles.

Do you work in Orleans?
Yes. Korvex Developments builds drainage, interlock, fences and decks across Orleans, in the 1970s neighbourhoods and the newer ones. One of our Orleans jobs is on this page: a weathered deck cleaned and sealed, which the homeowner reviewed on HomeStars. Request a free estimate or call 613-880-7679.
Why do patios and walls move on Orleans clay?
Much of Orleans sits on Champlain Sea clay, which holds water, and water in the ground expands when it freezes. A thin or poorly compacted base, or a surface that slopes toward the house, lets that movement show. A compacted granular base, fabric where the soil needs it and a set slope away from the house keep it in check.
Do I need a permit for a retaining wall?
It depends on the height. Under City of Ottawa rules, walls and steps that give access to the house can need a permit where surfaces differ by more than 600 mm, and landscape structures over 1 m high need an engineered design. We check what applies to your property before building.
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.
