Hobart Concrete Patio Contractors

For most Hobart homes, exposed aggregate or a light broom finish. Both give reliable grip when the surface is wet or frosty, which matters on a patio you step onto first thing on a winter morning, and both hide the marks outdoor living produces. Stamped and coloured finishes look excellent on a feature patio, though they need resealing periodically to hold their colour under strong Tasmanian summer UV. The one we steer people away from outdoors is a smooth trowelled finish — it photographs beautifully and turns genuinely slippery the first wet or icy morning.

Yes, and it's a large share of what we do, since flat ground is in short supply across much of Hobart. The approach is to cut into the slope to create a level platform, retain the cut so the bank stays put, and manage the water the cut will now intercept. That last part matters — excavating into a hillside changes where runoff goes, and a patio built without allowing for it becomes a collection point in a wet winter. Taller retaining walls may need council or building surveyor approval, so we check that early. Depending on the drop, you may also end up with a step or two down to the garden, built as part of the same job.

On site, typically several days to a week for a straightforward patio: form up, prepare the base, pour, finish, then strip the boxing. What extends it is everything around the slab — excavation on a slope, rock, retaining walls, drainage or steps. Weather plays a part too: through a Hobart winter we watch the forecast for frost and heavy rain around pour day, and cold temperatures slow curing. Light foot traffic is generally fine after a day or two, but leave furniture and the barbecue off for about a week. Decorative finishes add sealing time at the end. We give you the full timeline when we quote.

Fine hairline cracking is normal in any concrete and isn't a defect — concrete shrinks as it cures and has to relieve that somewhere. What we control is where it happens, by cutting control joints on a planned grid so cracking follows a straight line at a joint instead of wandering across the middle. What prevents the serious kind of cracking is the work underneath: proper excavation, a compacted crushed rock base and reinforcement through the slab. Many Hobart suburbs sit on reactive clay that swells through wet winters and shrinks over dry summers, and that groundwork is what stops the patio breaking into sections that settle independently.
