Artificial Grass Installation Guide
A premium step-by-step guide for preparing your base, laying synthetic turf, joining rolls, securing the perimeter and finishing your lawn with a professional brushed finish.
Plan first
Before you start your installation
A great artificial lawn starts before the turf is rolled out. Check the site, plan the grass direction, prepare your materials and make sure the base can drain correctly.
Confirm drainage
Water should not pool in the base. Add fall away from buildings and compact in layers.
Plan turf direction
Lay all rolls with the pile running the same way. Face the pile toward the main viewing area where possible.
Prepare tools
Have your knife, compactor, rake, level, nails or U-pins, joining tape, kiln-dried sand and broom ready.
Estimator
Quick material estimator
Use this quick guide to estimate area, excavation volume and base material. Final quantities may vary depending on site access, compaction rate, shape and installation conditions.
0m²exact ground space

Tip: for a 50m² area, 100mm depth equals approximately 5m³ of removed material or base volume before site-specific compaction and wastage. This calculator determines excavation and base materials only, the amount of artificial grass required may be a larger amount. Use our artificial grass calculator to determine exact materials required including the artificial grass of your choice.
Step-by-step
Professional artificial grass installation process
Follow each stage in order. The base is the most important part of the installation — a flat, stable and well-compacted base helps prevent dips, joins opening and uneven edges.
Step01
Excavate and shape the area
Excavate to allow enough depth for the crushed rock, stone dust and turf pile. In most residential areas, work from the lowest hard edge such as concrete, paving or edging.
- Remove existing grass, loose soil, roots and debris.
- Aim for around 100mm total depth from the lowest finished edge.
- Shape the subgrade so water can move away from buildings and low points.
- Compact the exposed soil before adding your rock base.
Pro tip: Calculate soil removal as length × width × depth. Every 10m² at 100mm depth is roughly 1m³.
Step02
Install the crushed rock base
Spread a solid crushed rock layer across the area. This layer provides strength, support and drainage below the synthetic turf.
- Use a minimum 70mm compacted crushed rock layer.
- Rake the rock level before compacting.
- Hose lightly and compact thoroughly.
- Top up and recompact any weak pockets or low areas.
Base mix guide: A practical ordering split is approximately two-thirds 20mm crushed rock and one-third stone dust.
Step03
Add stone dust and final level
Stone dust creates a smooth, firm surface under the turf. Take your time here — this is what gives the finished lawn its clean, even appearance.
- Spread stone dust evenly over the compacted rock layer.
- Screed or rake to remove ridges and high spots.
- Hose and compact until the surface feels firm.
- Finish the base roughly 10–20mm below the lowest surrounding edge.
Quality check: Walk the area and look for soft spots. Rework any areas that move under foot before laying turf.
Step04
Roll out, position and cut the grass
Roll the AusGrass turf out from the straightest edge first. Let the turf relax before final trimming where possible, especially on warm days.
- Lay every roll with the pile direction facing the same way.
- Trim the factory flap from both sides of the roll before joining or edging.
- Position the turf into the cleanest corner and check all edges before cutting.
- Cut from the backing side wherever possible using a sharp blade.
Cutting tip: Use small, controlled cuts and replace blades often for a cleaner edge.
Step05
Secure the perimeter
Once the turf is positioned correctly, secure it around the edge so it sits flush to the border without curling or lifting.
- Open the pile with your fingers before fixing to avoid trapping grass blades.
- Place nails or U-pins approximately 2–3cm from the turf edge.
- Space fixings around 20–30cm apart along the perimeter.
- Add extra fixings through the centre if needed for a more secure finish.
Finish tip: Fixings should disappear into the pile once the grass is brushed up.
Step06
Brush, sand and final groom
Kiln-dried sand helps support the base of the grass blades and improves the finished look of the lawn.
- Power broom or stiff-brush the grass upright before sanding.
- Spread kiln-dried sand evenly across the turf.
- Brush again to work the sand into the base of the pile.
- Do not brush wet grass or wet sand. Hose afterwards only if required.
Maintenance tip: Brush high-traffic areas occasionally to keep the pile standing naturally.
Simple line diagrams
Key installation details made easy
These clean diagrams help customers understand the most important details: base layers, turf direction and hidden fixings.
Recommended base profile
Typical residential build-up from compacted soil to finished turf.
Turf pile direction
Keep every roll facing the same direction for consistent colour and finish.
Hidden perimeter fixing
Open the pile before nailing so fixings sit low and are covered by the blades.
Larger areas
Joining artificial grass rolls
A clean join depends on matching the pile direction, trimming both edges neatly and keeping the blades out of the tape adhesive.
Trim both factory edges
Remove the flap on both joining sides and cut close to the stitch without damaging it.
Centre the joining tape
Fold both pieces back and position tape evenly underneath the join line.
Keep blades clear
Brush the blades away from the adhesive so they do not become trapped in the join.
Apply pressure as you peel
Remove the plastic cover gradually while pressing the turf down to stop the join moving.
Aftercare
Keep your new lawn looking fresh
Artificial grass is low maintenance, but a simple care routine will help protect the finish in high-use areas.
Brush high-traffic zones
Use a plastic rake, stiff broom or power broom to lift flattened pile in walkways and play areas.
Rinse when needed
Hose pet areas, food spills or dusty sections to keep the surface clean and fresh.
Treat surface weeds
Occasional surface weeds can be removed by hand or treated carefully with a suitable general weed killer.
Quality control
Common issues and how to avoid them
| Issue | Likely cause | Prevention or fix |
|---|---|---|
| Dips or potholes appearing | Soft pockets in soil or base not compacted enough. | Compact the soil, crushed rock and stone dust in stages. Top up low areas before turf is installed. |
| Visible joins | Pile direction mismatch, uneven trimming or blades stuck in tape. | Keep rolls facing the same way, trim neatly, centre the tape and brush blades away from adhesive. |
| Raised or curling edges | Perimeter not fixed securely or turf cut under tension. | Let turf relax, cut carefully and fix 2–3cm from the edge at close spacing. |
| Sand sitting on top of grass | Sand applied unevenly or grass brushed while wet. | Use dry kiln-dried sand, spread lightly and brush into the base of the pile while dry. |
FAQ
Artificial grass installation questions
How deep should I excavate for artificial grass?
A common residential guide is around 100mm from the lowest finished edge, allowing room for the compacted crushed rock, stone dust and turf pile.
What base should I use under synthetic turf?
Use a stable crushed rock layer for strength and drainage, followed by stone dust to create a smooth, compacted final surface.
Do all turf rolls need to face the same direction?
Yes. Lay all rolls with the pile direction facing the same way to avoid colour and texture differences between pieces.
When should I add kiln-dried sand?
Add kiln-dried sand after the turf has been cut, joined and secured. Brush the grass first, spread sand evenly, then brush again to work it into the pile.
Can artificial grass get weeds?
Weeds are usually surface weeds from wind, birds or surrounding gardens. Regular cleaning and occasional treatment can help keep the surface tidy.

Golf Putting Pro installation guide
How to install Golf Putting Pro
Golf Putting Pro is a short, tightly packed artificial putting grass engineered for a smooth, consistent ball roll. The base preparation follows the standard Ausgrass artificial grass installation method, but the finishing process is different because the Putting Pro should not be traditionally nailed through the putting surface.
Complete the standard base preparation first
Excavate, install and compact the crushed rock and stone dust layers as normal. Take extra care to create a smooth, firm and accurately graded surface because the short putting pile will reveal imperfections more readily.
1
Shape and cut the Golf Putting Pro
Plan the final shape of your putting green and cut the Golf Putting Pro to suit. If more than one piece is needed, join the Putting Pro sections while keeping the pile direction consistent so the playing surface rolls uniformly.
Golf tip: Smooth, flowing curves create a more unique finished green and make the surrounding rough more interesting.
2
Install the cup and flag base
Before laying the artificial grass, install the golf cup into the prepared crushed rock and stone dust base. Set the cup firmly so the top edge sits approximately 10mm above the finished compacted stone dust level.
This raised edge allows the cup to be felt through the Golf Putting Pro after the turf is laid, making it easy to locate the exact position for the hole. It is also important to a later step.
Important: The cup is installed into the base before the Golf Putting Pro is laid over the area.
3
Cut the landscaping turf rough
Use a longer landscaping artificial grass around the Golf Putting Pro to recreate the rough surrounding a natural golf green. Cut the inside edge of the rough so it follows the exact perimeter and curves of the putting surface.
Recommended: Allow a minimum rough width of 100mm to create a practical border for joining and perimeter fixing.
4
Dry fit the putting green and rough
Place the Golf Putting Pro and rough into their final positions. Trim small amounts where required until the two turf edges meet tightly and follow the same shape with no visible gaps or overlaps.
Quality check: Inspect the full perimeter before joining. A precise dry fit produces the cleanest finished edge.
5
Join the Putting Pro to the rough
Join the putting surface to the rough using artificial grass joining tape or suitable artificial grass adhesive. For curves, cut the joining tape into shorter pieces and place each piece edge to edge so the pieces touch continuously beneath the join.
Do not leave gaps between the tape pieces. Bring the two turf edges tightly together and press firmly along the complete seam.
Curved joins: Use multiple short touching tape pieces so the joining line can follow the curve without pulling the green out of shape.
6
Cut the hole tightly around the cup
Feel through the Golf Putting Pro to locate the raised edge of the cup underneath. Carefully cut the opening around the cup with a sharp utility knife.
Cut the hole tightly so the turf requires a small amount of pressure to squeeze around the cup, creating a snug, neat finish.
Pro tip: Avoid over-cutting. A tight fit produces the cleanest edge around the golf cup.
7
Fix the rough — not the putting surface
Once the joins are secure, nail the outside perimeter of the rough and then install fixings through the rough beside the inside joined edge where it meets the Golf Putting Pro.
Important: Do not install nails through Golf Putting Pro. Every nail must remain within the longer landscaping turf rough.
8
Apply and brush in the sand infill
Apply the recommended quantity of kiln-dried sand evenly across the Golf Putting Pro and brush it thoroughly into the short pile.
The weight of the sand helps hold the Golf Putting Pro flat and stable without nails through the putting surface, while the quantity and distribution of sand help control the speed and consistency of the ball roll.
Performance: Brush the sand evenly over the complete putting surface for the most consistent roll.
