Interlock patios and walkways in Riverside South
Interlock patios, walkways and steps for Riverside South homes, set at the height and slope the lot’s grading plan calls for. Most lots here are recent, and the patio has to keep that plan working.

The local picture
Interlock in Riverside South
The City’s design plan for Riverside South sends lot runoff into the Mosquito Creek valley and a set of stormwater ponds. Owners are expected to keep the grades from the original grading plan and never cover swales or catch basins. Patio height and slope are set to match, and newer homes are more likely to have the plan on record with the City.
The community plan calls for tree planting standards suited to marine clay soils. Clay under a new yard holds water, so base depth and compaction are planned for it, and fabric keeps the gravel base from mixing into the soil below.
Interlock for Riverside South’s newer homes
First patios, front walks and repairs
Korvex Construction builds first patios, front walkways and steps for Riverside South homes and relays interlock that has settled. We work on the established streets and the newer phases between the Rideau River and Bowesville Road, from the first neighbourhoods to the streets around Limebank Station. To book the free on-site estimate, use the form or call 613-880-7679.
The first homes here went up in 1996, so the oldest patios here can be about thirty years old while other yards have yet to get one. Each phase brought its own builder walk and grading plan.
Before the first patio
What a new backyard already has in it
A catch basin in a backyard serves your lot and the lots around it, and the City asks owners to keep catch basins clear. When a patio is planned near one or along a swale, the paving stops short of it and is sloped so its water reaches the grate, which stays open and reachable.
A new yard also has its fixtures: the air conditioner pad, the gas meter, the deck or the patio door step, and the side-yard swale between houses. The patio shape is drawn around them, so nothing ends up buried or boxed in.
Lots that back onto the Mosquito Creek valley keep patio runoff and any spare fill out of the valley slope.
Front walks on streets still being built
Road works are still part of life in a growing community. When the City rebuilds a road and that affects an entrance that meets the Access By-law, the City reconstructs the entrance at no cost to the owner. An entrance that does not meet it is replaced with one that does.
The by-law also makes owners responsible for keeping every entrance that serves their property, steps included, from causing injury or damage. A front walk that has dropped where it meets the sidewalk is a trip edge, and relaying it on a rebuilt base removes it.

- Recent lots and grading plans
Owners are expected to keep the grades set by the original grading plan, and swales and catch basins stay open. Newer homes are more likely to have that plan on record with the City.
- Marine clay soils
The community plan calls for tree planting standards suited to marine clay soils. Clay under a new yard holds water, so base depth and compaction are planned for it.
How we build it
What goes under an interlock patio
A patio stays flat when the base under it is deep enough, compacted and sloped.
- Excavation
Grass, topsoil and roots come out. Organic soil compresses and rots.
- Slope
The surface falls away from the house, so water runs off, away from the foundation.
- Compaction
Compacted and checked before the sand. Loose base is the main reason pavers sink.
- Edges
Edges are held in place so pavers stay tight and in line.
- Pavers or slabsSet on a slope so rain runs off the surface and away from the house.Set on the bedding
- Sand bedding layerScreeded flat by hand so every paver sits evenly.Screeded flat
- Compacted gravel baseCompacted in stages. This layer carries the load through freeze and thaw.Placed in lifts
- Geotextile fabricKeeps the base gravel from mixing into the soil below.Laid over the soil
- Excavated native soilTopsoil and soft ground are dug out before the base goes in.To firm ground

FAQ
Interlock in Riverside South: common questions
Where should our first patio go?
Usually off the main door to the backyard, clear of the catch basin and swale, at a height that sits below the door sill. We look at sun, the deck or step, the drainage the lot was graded for and how you want to use it, then mark the shape on site.
There is a catch basin in our backyard. Can the patio go around it?
Yes, as long as the catch basin stays open. City guidance says catch basins help your lot and the neighbours’ lots drain and should never be blocked. The patio stops short of it and is sloped toward it, so it keeps doing its job.
What should we have ready for the estimate?
Your lot survey and grading plan if you have them, photos of where water sits after rain, and a list of anything buried, such as gas to a barbecue or power to a shed. With those we can plan the patio and give you a written quote after the site visit.
Can you extend the patio that came with the house?
Yes. The new section is built on its own dug-out, compacted base and matched to the existing height and slope, so the two surfaces drain together. We check the grading plan first.
Will a new patio affect our lot grading?
It can, so the patio is built to fit the plan. City of Ottawa rules expect owners to keep the grades from the original grading plan and never cover swales or catch basins. We check what applies to your property and set patio height and slope to match.
Why are my pavers sinking?
Pavers sink when the base under them is too thin, was never properly compacted, or sits on soft or organic soil. Water gets into the low spots, freezes and moves the surface a little more each winter. Korvex fixes it at the source: the pavers come up, the base is dug out and rebuilt in compacted layers, and the surface goes back on a slope.
