Concrete Patios in Bowmanville
We pour concrete patios across Bowmanville and the rest of Clarington. The ground is clay-loam that heaves under a thin base, so the base and the slope matter more than the slab. Near the lake the water table sits high, and on new lots the fill is still settling. Union-certified crews, a free written quote that holds, and a lifetime warranty on labour.

Bowmanville has older brick streets around King Street and new surveys at the north and west ends of town. A patio needs different things in each.
The core method is the same everywhere: a compacted granular base, 32 MPa air-entrained concrete, and a slope of about 2 percent away from the house. The full spec is on our concrete patios page. This page covers what Bowmanville ground and homes change about the job. For everything else we do in town, see our Bowmanville page.
Clay-loam under the slab
Most of Bowmanville sits on South Slope till, a clay-loam left by the glaciers. It drains slowly and holds water. When that water freezes under a patio on a thin base, it lifts the slab and can tip it toward the house.
So we dig to stable ground, build the base up in compacted layers, and set the slope so rain and melt water run away from the foundation. Where a downspout empties onto the patio, we plan for it before the pour.
Older homes near King Street and the lake
The older blocks near King Street have original foundations and parging that has let go. Closer to Lake Ontario the water table sits high. A patio that is flat, or that has settled toward the wall, sends water to the very place that already struggles.
Before we pour against an older house, we look at the wall, the downspouts and any steps that have sunk. If the wall already lets water in, we tell you. We can look at basement waterproofing in Bowmanville first, so the patio does not go in on top of the problem.
New surveys: wait for the ground
On a new lot in north or west Bowmanville, the fill keeps settling for a season or two. A patio poured too early can sink at the house edge. We usually suggest waiting until after the first full spring, and we check the ground before we pour.
Spring is a good time to ask for a quote, because summer books up fast on the growing ends of town. Bowmanville is the far east end of the Durham towns we cover, so we book Clarington jobs into planned trips east and give you a real date.
Straight answers
We bought new in north Bowmanville. When can we pour a patio?
Usually after the first full spring. New-survey ground keeps settling for a season or two, so we check it before we pour. Get a written quote in spring, because summer books up fast.
Will a new patio make my old Bowmanville basement wetter?
Not if it is built right. We slope every patio about 2 percent away from the house and check where your downspouts empty. If your wall already lets water in, we tell you before we pour.
Do you pour patios in Courtice, Newcastle and Orono too?
Yes. They book onto the same trips east as Bowmanville. The job is the same: a free site visit, a written quote, the pour on a proper base, and the labour warranted for life.
How much does a concrete patio cost in Bowmanville?
The finish you pick, how easily a truck can reach the backyard, the size and the base the ground needs set the number. We do not post a flat rate that would only mislead you. You get a free written quote after a site visit, and the number on it is the number you pay unless you change the job.
