A Sunshine Coast guide to laying synthetic turf on hard surfaces — rooftops, balconies, courtyards, and driveways.
One of the most common questions we get from Sunshine Coast homeowners and businesses is whether artificial grass can go straight over an existing hard surface — concrete slabs, pavers, decking, or even old tiles. It’s a great question, especially if you’re working with a rooftop, balcony, courtyard, or paved area you’d rather transform than dig up.
The short answer: yes, artificial grass can absolutely be installed over concrete and pavers — and in many cases it’s actually a simpler, faster job than installing over soil. But it’s done differently, and getting a few details right makes the difference between a lawn that looks great for years and one that shifts, wrinkles, or holds water.
Why Hard Surfaces Are a Good Candidate for Artificial Grass
Concrete and paved areas are common across the Sunshine Coast — think rooftop entertaining areas in Maroochydore and Mooloolaba apartments, tired courtyards in older Buderim homes, tiled balconies overlooking the coast, or a cracked driveway that’s seen better days. These spaces are often awkward to landscape because there’s no soil to work with, but that’s exactly where artificial grass does well: it doesn’t need soil to thrive, and it can turn an unused slab of concrete into a genuinely usable green space.
It’s also a popular option for:
- Rooftop terraces, where weight, drainage, and waterproofing matter more than anything
- Balconies, where space is tight and a soft, natural-looking surface makes a big difference underfoot
- Pool surrounds with existing concrete or paved edging
- Courtyards and side passages where garden beds aren’t practical
- Driveways and pathways, either as a full surface or a decorative strip between pavers
How Installation Over Concrete Differs from Installing Over Soil
When artificial grass goes over soil, the base layer does most of the work — it’s excavated, compacted, and built up to create drainage and a stable, even surface. Over concrete or pavers, that step isn’t needed in the same way, but a few other things become far more important:
- Surface prep. The existing concrete or paving needs to be clean, structurally sound, and free of major cracks or unevenness that could telegraph through the turf over time. Any significant damage generally needs repairing first.
- Drainage. This is the single biggest difference. Unlike soil, concrete doesn’t drain — so water needs somewhere to go, or it will pool underneath the turf. Depending on the site, this might mean a shock pad with drainage channels, a perforated underlay, ensuring existing drainage points and falls are maintained, or in some cases drilling drainage holes into the slab itself.
- A cushioning underlay. Because there’s no soil to soften the feel of the surface, a shock pad or foam underlay is usually installed beneath the turf. This makes the lawn feel softer and more natural underfoot, helps it drain, and adds a bit of cushioning — particularly important for kids’ play areas or pet zones on hard surfaces.
- Securing the turf. Instead of pins driven into soil, turf on hard surfaces is typically secured using a combination of adhesive, turf tape at the seams, and sometimes a perimeter edging trim, so it stays flat and doesn’t shift with foot traffic or wind (a real consideration on exposed rooftops).
- Weight considerations for rooftops. If you’re covering a rooftop or elevated structure, the combined weight of turf, underlay, and any infill needs to be checked against what the structure can safely support — this is worth confirming with a professional before installation, especially on older buildings.
Common Questions About Turf Over Hard Surfaces
Will it look obviously fake sitting on top of concrete? Not if it’s installed properly. A good shock pad or underlay softens the transition and prevents the turf looking flat or stretched tight over the slab, and neatly finished edges (using edging strips or garden borders) hide the transition between turf and surrounding surfaces.
What happens when it rains? This comes down entirely to how the drainage was planned before installation. On a well-installed system, water runs off through the underlay and existing drainage points just as it would off any outdoor hard surface. This is why drainage planning matters more here than almost any other part of the job — it’s worth asking directly how a prospective installer plans to handle it for your specific site.
Can it be removed later if needed? Generally, yes — turf installed over a hard surface with adhesive and tape can be lifted, which is one advantage over installations bonded directly into soil. This is worth checking with your installer if you’re in a rental property or planning future renovations.
Is it suitable for balconies and rooftops in coastal, windy areas? Yes, with the right fixing method. Coastal Sunshine Coast properties often deal with stronger winds at height, so secure edging and adhesive application matter more here than in a sheltered backyard.
Things to Check Before You Get Started
If you’re considering artificial grass over an existing hard surface, a few things are worth clarifying with whoever you’re getting quotes from:
- How will drainage be managed for your specific site and surface?
- What underlay or shock pad will be used, and how thick is it?
- For rooftops — has weight load been considered, and does it need sign-off from a builder or engineer?
- How will the turf be secured, and is it removable if needed?
- How will edges and transitions to other surfaces be finished?
A quick note: costs for installing over concrete or pavers can differ from a standard soil installation — sometimes less because there’s no excavation, sometimes more if drainage upgrades or a premium shock pad are needed.

The Bottom Line
Concrete, pavers, tiles, and decking don’t rule out artificial grass — in many cases, they’re an ideal base for it, particularly for rooftops, balconies, and courtyards where a traditional lawn was never going to be an option. The key is proper drainage planning and the right underlay, which is exactly the kind of detail a professional installation gets right the first time.
