Pool surrounds are one of the most satisfying pours we do, and one of the least forgiving. By the time the surround is ready, the backyard is at its most vulnerable: an expensive shell in the ground, new fencing, retaining walls, drainage, half the landscaping done. Into this delicate scene you now need to deliver fifteen-odd cubic metres of (usually decorative) concrete, placed neatly against a fixed coping line.
Here's how it's done properly.
Why pool surrounds are pump jobs by default
Think about what the alternative looks like: a concrete truck can't get within cooee of most backyards, so without a pump you're barrowing every load through the side gate — across new paving, past the shell, hundreds of trips, with concrete stiffening in the truck the whole time. Slow, messy, and genuinely risky around a pool shell and fresh landscaping.
A line pump solves the whole problem from the street. The pump stays at the kerb, the line runs over the fence or down the side access, and concrete arrives at the coping edge at walking pace, exactly where the finishers want it. The backyard sees nothing heavier than a hose.
Planning the line route
The route is the job. Before pour day we work out:
- Entry path: over the fence with rigid line and protection on the capping, or down the side access if it's walkable. Occasionally through the garage or house — with floor protection laid first.
- What the line must not touch: new paving, garden beds, irrigation, the pool itself. We physically protect contact points and keep joints off delicate surfaces.
- Where the line ends: the pour sequence around the shell determines where the hose needs to reach and in what order. Nobody wants to drag a concrete-filled hose across a freshly poured section.
Protecting the shell
Fibreglass and concrete shells are both tougher than they look and more expensive than anyone wants to test. Our working rules around pools:
- No line dragged across coping or shell edges — we lift and reposition, or use stands.
- A full shell is a stable shell. If the pool is already filled, good; if it's empty, we treat the surrounds as even more fragile and keep loads and line pressure well away from the beam.
- Wash-out happens at the street in our containment — never anywhere that drains toward the pool. Cement slurry and pool chemistry are not friends.
Decorative mixes around a fixed edge
Most surrounds are poured in exposed aggregate, honed mixes or coloured concrete, and they meet an unforgiving straight edge at the coping. That combination punishes sloppy pumping:
- Feed rate must be steady. Surging segregates decorative mixes and the stone distribution shows forever in an exposed finish.
- The line must be clean. Residue from a previous grey pour contaminating a coloured mix is an expensive mistake we've been called to fix — never to make.
- The pour tracks the finishers. Around a pool, the crew works in a sequence — coping edge first, panels back from the water, joints on the plan. The pump feeds that sequence at their pace, not the pump's convenience.
Sequencing with the pool builder and landscaper
Pool projects involve a parade of trades, and the surround pour sits in the middle of it: after plumbing, drainage and steel; before fencing final, decking and planting. The classic scheduling failures are pouring before an inspection that needed the steel visible, and pouring after landscaping that then gets trampled. We coordinate directly with pool builders and landscapers every week — tell us who's running the project and we'll slot into their program rather than making you the messenger.
What it costs
A typical Melbourne pool surround (10–20m³, line pumped over a fence, decorative mix) prices like a small slab job with a care premium — see our cost guide for realistic ranges. The two variables that move it most are line run length and anything unusual about access. Photos of the side access and backyard with your enquiry get you an accurate number first time.
