Brisbane Weather and Your Pool Build: When the Rain Comes

Brisbane has a wet season. Officially November to March, practically anywhere from late October to early April. And during a 12-week pool build there's a decent chance some of it will fall on your job.

The honest question isn't whether weather will affect your build — it almost certainly will at some point — but how we handle it when it does. Here's the playbook.

What we can work in

Light rain, drizzle, overcast: business as usual. The trades come, the site runs, progress happens.

Heavy showers under a couple of hours: we may pause for an hour or two and pick back up. Most of the time we just press on with whatever doesn't need dry conditions.

Persistent rain or storms: site shuts down for safety and quality. There's no point pouring concrete in the wet — it sets badly, the finish is compromised, and steel work is dangerous in slippery conditions.

The five worst-case rain scenarios

Each stage of a build has a different relationship with rain. The biggest issues:

1. Excavation in saturated ground. A waterlogged hole collapses or fills with water. We'll wait a day or two for the ground to dry rather than dig in mud and have to redo it.

2. Steel work in heavy rain. Trades on steel mesh in wet weather is a slip-and-fall risk we won't take. Steel doesn't suffer from a delay — we put it off and pick up Monday.

3. Shotcrete during rain. The single biggest weather risk. Rain on freshly sprayed shotcrete ruins the finish and weakens the cure. We'll shift the spray date by days if the forecast looks dodgy.

4. Pebble-crete application. Same story. The interior finish needs dry conditions to cure properly.

5. Paving in mud. Coping and paving need a stable, clean base. Wet ground means the base fails and pavers shift.

How we plan around it

Three things, every build:

• 14-day weather buffer in every project schedule. If we land in storm season we can take a week or two of weather without the final handover slipping.
• Daily forecast monitoring. Our PMs check 7-day BOM forecasts every morning. We're rescheduling shotcrete and pebble-crete days a week ahead based on what's coming.
• Dry-job stockpile. Even when we can't pour or spray, there's almost always something dry we can do — fence prep, plumbing layout, coping setup. We'll keep things moving where we can.

What you'll see during a wet week

If we're paused for weather, you'll get a text from your PM: 'Wet week ahead, site closed Tuesday-Thursday, back in Friday.' That's it. We don't disappear and reappear without warning.

Sometimes the site will look quiet for a few days. That's fine — it's normal. As soon as conditions allow, the trades roll back in.

Storm season specifics

If your build runs through Jan-Feb, expect 2-4 weather days, possibly more in a wild season. We've had jobs in 2022 (massive flood season) where we lost three weeks total to weather. Most years it's much less.

If you're scheduling a build and want to avoid the worst of storm season altogether, sign-ups in May-July tend to land construction in our drier window (Aug-Oct). But we build year-round and it works either way.

One last note on rain

The pool fills up with water during storms. That's normal — we leave a sump in the bottom of every excavation, and we pump out before the next phase of work. It's not damage, it's just rain doing what rain does.

If you're planning a build, the time of year matters less than you'd think. Get in touch and we'll talk through what timing makes sense for your situation.
