Why Georgetown projects need a tailored approach
Georgetown sits on Halton Till with shallow shale on the north and east edges of town, and the homes we work on are spread across neighbourhoods like Georgetown South, Park District, Delrex, Moore Park, Glen Williams and along Mountainview Road North. Older Georgetown South lots near the Credit River have alluvium and high water table; newer subdivisions off Mountainview Road North sit on tighter till that drains slowly. Combined with Snow belt, more severe freeze-thaw than the lakeshore, escarpment runoff after heavy rain, this changes how we design the slab and the base.
We pull permits where needed through Town of Halton Hills Building Department (1 Halton Hills Drive), so the work is documented and inspected, not buried under landscaping. Whether you are in postal code area L7G, we serve every Halton Hills address with the same crew, the same supervisor, and the same written quote.

How a Georgetown concrete patio is built
- Slab thickness: 100 mm (4 in) for foot traffic, 125 mm (5 in) for outdoor kitchens or hot-tub-adjacent areas.
- Concrete mix: 32 MPa, 5-7 percent air entrainment so the slab survives Georgetown's freeze-thaw cycles.
- Reinforcement: 10 M rebar at 400 mm on centre, chaired to mid-slab. We do not rely on wire mesh that ends up on the sub-base.
- Sub-base: 150 to 200 mm of compacted Granular A, plate-tamped in lifts.
- Slope: 2 percent fall away from the house, more on shaded north-side patios where ice is a risk.
- Control joints: saw-cut within 12-24 hours at slab-thickness x 24 to 30, broken into roughly square panels.
Our patio installation process
- Step 1. Design consult. We measure, mark service locations, and discuss finish, colour and joint pattern. For stamped patios we bring sample boards.
- Step 2. Excavation and base. We strip topsoil, compact the sub-grade, and install Granular A in 100 mm lifts.
- Step 3. Forms and reinforcement. Side forms staked to grade, rebar grid chaired off the base, and any drain inlets or post sleeves preset.
- Step 4. Pour and finish. 32 MPa concrete placed, screeded, bull-floated, then finished to your selected texture (broom, exposed aggregate wash, or stamp impressions).
- Step 5. Saw-cuts and protection. Control joints cut within 12-24 hours, then the slab is covered or kept damp during cure.
- Step 6. Sealing and walkthrough. We return at 28 days for a high-solids penetrating or acrylic sealer and walk the patio with you.
Frequently asked questions about concrete patios in Georgetown
These are the questions we are asked most often when quoting jobs in Georgetown and surrounding Halton Hills communities.
+ What size patio do most Georgetown homeowners build?
Around 14 ft x 16 ft to 16 ft x 20 ft is typical for a dining-and-lounging patio in Georgetown, depending on lot setback. Larger homes in Georgetown South, Park District, Delrex often go to 18 ft x 24 ft with a separate BBQ area. Lot grading and rear-yard drainage drive the upper limit more than budget does.
+ Stamped vs exposed aggregate, which lasts longer in Georgetown?
Both perform well when built properly. Exposed aggregate has the better long-term track record in Georgetown because the surface is the aggregate itself, so Snow belt freeze-thaw and de-icer abuse just take micro-amounts of cement paste off the top. Stamped patios look spectacular but the colour-hardener layer is sacrificial; expect to re-seal every 2-3 years.
+ Do I need a permit for a patio in Georgetown?
A free-standing concrete patio at grade typically does not need a building permit through Town of Halton Hills Building Department (1 Halton Hills Drive), but rear-yard setback rules and lot-grading approval still apply. If the patio includes a pergola, hot-tub electrical, or any roof structure, those add a permit. We confirm requirements before quoting.
+ Why do concrete patios crack and how do you minimize it?
Concrete shrinks as it cures and the slab moves with temperature. We minimize random cracks by saw-cutting control joints at the right time and depth, by reinforcing with rebar (not just mesh), and by building on a properly compacted base. Halton Till with shallow shale on the north and east edges of town adds risk if the sub-grade is not done right.
+ How soon can we use a new patio?
You can walk on it at 24-48 hours. Furniture goes back at 7 days. We hold off on heavy planters, BBQs and hot tubs for 28 days while the slab reaches design strength, then we seal.
