Yes, you can lay artificial grass over concrete, pavers or decking, provided the surface is clean, stable, reasonably level and able to drain properly. These hard surfaces are often used in patios, balconies, courtyards, pool areas, entertaining spaces and small outdoor areas where natural lawn is difficult to grow or maintain.
At R2'ficial, we supply and install premium artificial lawn for Perth homes and businesses. Whether you are transforming an old paved patio, covering a concrete courtyard or softening a decked area, the right preparation makes all the difference.
Can You Lay Artificial Grass Over Concrete?
Yes, you can lay artificial grass over concrete. Concrete is one of the most common hard surfaces used as a base for synthetic grass, especially in courtyards, balconies, patios and outdoor entertaining areas.
The main thing to remember is that concrete does not drain like a prepared crushed rock base. If water already pools on the concrete, it may continue to pool underneath the turf unless drainage is improved first. The concrete should also be cleaned, repaired and checked for uneven areas before installation.
For the best result, many hard-surface installations benefit from a suitable foam underlay, drainage layer or shock pad. This can make the artificial grass feel softer underfoot and help reduce the harsh feel of concrete beneath the turf.

Can You Lay Artificial Grass Over Pavers?
Yes, artificial grass can be laid over pavers if the pavers are stable, level and well-drained. This is a popular option for turning old paved patios, pathways and entertaining areas into a softer, greener space without removing the existing surface.
Before laying artificial grass over pavers, check for loose, sunken, cracked or uneven pavers. Artificial grass will follow the shape of the surface underneath, so any major bumps, dips or gaps may still show through after installation.
For a smoother finish, larger gaps between pavers should be addressed before the turf is installed. A suitable underlay can also help reduce the appearance of joins and create a more comfortable surface.
Can You Lay Artificial Grass Over Decking?
Yes, you can lay artificial grass over decking, but the deck must be structurally sound, secure and able to drain. Artificial grass can work well over timber or composite decking, particularly on balconies, rooftop spaces and outdoor entertaining areas.
The biggest issue with decking is moisture. If water becomes trapped between the artificial grass and the deck, it can lead to mould, odours or timber damage over time. For this reason, it is important that water can escape and air can circulate beneath the turf.
If your decking is old, soft, rotten or moving underfoot, it should be repaired before artificial grass is installed. Avoid fully sealing turf to timber decking in a way that blocks drainage or traps water.
Benefits of Laying Artificial Grass Over Concrete, Pavers or Decking
Installing artificial grass over hard surfaces is a practical way to improve the look and feel of an outdoor area without a full landscape rebuild.
- Creates a softer surface for patios, courtyards and balconies
- Improves the appearance of plain concrete, old pavers or tired decking
- Provides a low-maintenance green space all year round
- Suitable for small spaces where natural grass will not grow well
- No mowing, watering or fertilising required
- Can be suitable for kids, pets and entertaining areas when installed correctly
For larger projects, uneven areas or spaces with drainage concerns, professional installation may be the better option. You can learn more about our artificial grass installation Perth services.
What to Check Before Installing Artificial Grass on a Hard Surface
1. Drainage
Drainage is the most important factor when laying artificial grass over concrete, pavers or decking. Water needs somewhere to go after rain, cleaning, pool splash or pet use.
Concrete should ideally have a slight fall toward a drain. Pavers should be stable and allow water to escape through existing drainage points. Decking should allow water and air to move underneath the surface.
2. Surface Condition
The surface should be clean, firm and free from loose material. Cracked concrete, uneven pavers or damaged decking boards should be fixed before installation.
3. Comfort Underfoot
Hard surfaces can make artificial grass feel firmer than a traditional lawn base. If comfort is important, especially for children, pets or entertaining areas, consider using an underlay or shock pad.
4. Adhesion and Fixing
Artificial grass can be secured using suitable outdoor adhesive, joining tape, perimeter fixing or a combination of methods. The best fixing method depends on the surface, the size of the area and whether water needs to pass underneath.
5. Heat and Sun Exposure
Concrete, pavers and decking can retain heat in direct sun. Artificial grass may also become warm during hot Perth weather. Choosing a quality turf product and using the right installation method can help improve comfort and long-term performance.
How to Lay Artificial Grass Over Concrete
- Clean the concrete thoroughly and remove dirt, dust, grease and loose material.
- Check that the concrete drains properly and does not hold standing water.
- Repair cracks, sharp edges or uneven areas where required.
- Roll out the artificial grass and allow it to settle before cutting.
- Trim the turf carefully to suit the space.
- Use joining tape if multiple pieces of turf are required.
- Secure the turf with a suitable hard-surface fixing method.
- Brush the grass fibres upright for a natural finish.
How to Lay Artificial Grass Over Pavers
- Check that all pavers are level, stable and secure.
- Fix loose or sunken pavers before installation.
- Clean the paved surface thoroughly.
- Fill or smooth large gaps if needed.
- Install a suitable underlay if you want a softer and smoother finish.
- Roll out, position and trim the artificial grass.
- Join multiple pieces using joining tape if required.
- Secure the perimeter and brush the pile upright.
How to Lay Artificial Grass Over Decking
- Inspect the deck for loose, rotten or damaged boards.
- Repair any structural issues before installing turf.
- Clean the decking surface.
- Make sure water can drain and air can circulate.
- Roll out the artificial grass and let it settle.
- Trim the turf to fit the decked area.

Do You Need Underlay Under Artificial Grass?
You do not always need underlay under artificial grass, but it is often recommended when installing over concrete, pavers or decking. Hard surfaces can feel very firm, and underlay can help create a softer, more natural feel.
Underlay may help:
- Improve comfort underfoot
- Reduce the harsh feel of concrete or pavers
- Smooth out minor imperfections
- Reduce the appearance of paver joins
- Add cushioning for kids or pets
- Support better water movement when the correct drainage layer is used

Can Pets Use Artificial Grass Over Concrete or Pavers?
Yes, pets can use artificial grass installed over concrete or pavers, but drainage and cleaning are especially important. Pet urine needs to drain away properly to help prevent odours.
If the area will be used by dogs, choose a pet-friendly artificial grass with good drainage. You should also clean the area regularly with a suitable turf cleaner and avoid installing over hard surfaces where water or urine cannot escape.

Common Mistakes to Avoid
- Laying artificial grass over a surface with poor drainage
- Installing over loose, cracked or uneven pavers
- Covering rotten or unstable decking boards
- Using the wrong adhesive or fixing method
- Skipping surface cleaning before installation
- Trimming the turf before allowing it to settle
- Fully sealing turf over timber decking in a way that traps water
- Choosing low-quality turf for high-traffic areas
Is It Better to Remove Concrete, Pavers or Decking First?
In many cases, you do not need to remove concrete, pavers or decking before installing artificial grass. If the existing surface is stable, level and drains properly, it can often be used as a base.
However, removal or extra preparation may be required if:
- The surface is badly damaged
- Water pools and cannot drain away
- The area is very uneven
- The decking is rotten or unstable
- The finished turf height will create a trip hazard
- You want a more traditional crushed rock and compacted base
If you are unsure which option is best, contact the R2'ficial team for advice or visit our Forrestdale artificial lawn showroom.
How Much Does Artificial Grass Installation Cost?
The cost of artificial grass installation depends on the size of the area, the turf selected, preparation required, access, drainage and whether you are installing over soil or an existing hard surface.
