Booking an artificial grass installation is the exciting part. The preparation that happens before the installer arrives, or before you start a DIY project, is what determines how well the finished lawn performs and how long it lasts. A poorly prepared site is the root cause of the vast majority of artificial grass problems, from uneven surfaces and drainage failures to premature base settlement.<\/span><\/p>\n

The good news is that most of this preparation is straightforward once you know what you are looking for. Here is a systematic guide to getting your backyard ready for a turf installation.<\/span><\/p>\n

Step 1: Site Assessment<\/b><\/h2>\n

Before anything is touched, take time to genuinely assess what you are working with. Walk the space and note the existing surface type, whether it is lawn, bark chips, pavers, or concrete, because each requires a different removal approach and affects the cost of the job. Look at how water currently moves across the yard during and after rain. Are there sections that pool or stay wet for extended periods? Are there areas where the ground is noticeably lower than others? These observations inform your drainage planning directly.<\/span><\/p>\n

Check the soil type if you are installing over soil. Clay soil, which is common across Melbourne, Adelaide, parts of Sydney, and much of regional south-eastern Australia, retains water and expands and contracts seasonally. This requires a more robust drainage and base preparation approach than sandy or loamy soils. If you are unsure of your soil type, a simple test is to pick up a handful of moist soil and squeeze it. Clay holds its shape and feels smooth and plastic. Sandy or loamy soils crumble.<\/span><\/p>\n

Note any tree root systems that could push upward through the installation over time, any irrigation infrastructure that will need to be capped or rerouted, and the access points available to get machinery into the space. A narrow side gate that prevents bobcat access significantly affects the removal and base preparation methodology and should be discussed with your installer at the quoting stage.<\/span><\/p>\n

Step 2: Remove Existing Grass and Vegetation<\/b><\/h2>\n

The existing lawn and any other vegetation in the installation area needs to be completely removed before base preparation begins. This is not optional. Natural grass, weeds, and organic material left under a turf installation will decompose over time, causing the base to sink and the surface above it to develop dips and unevenness.<\/span><\/p>\n

For a DIY approach, a sod cutter or turf cutter, available from most tool hire companies, removes lawn efficiently. The cut material is then lifted, loaded, and disposed of. A bobcat with a bucket is faster for larger areas and allows the entire excavation and load-out to be completed in a single phase.<\/span><\/p>\n

After removing the vegetation layer, the subgrade is excavated to the required depth. A standard residential installation requires excavating to approximately 100 to 120mm below the intended finished surface level. This provides the depth needed for the aggregate base and a thin levelling layer without raising the finished turf level excessively above surrounding surfaces.<\/span><\/p>\n

Step 3: Drainage Planning<\/b><\/h2>\n

Good drainage is the foundation of a good artificial grass installation, and planning it before the base goes in is far easier than trying to fix it after the fact. Synthetic turf itself is permeable, but it relies on the base below it to move water away. A base that is not graded correctly, or that sits on impermeable clay without adequate drainage engineering, will develop pooling problems.<\/span><\/p>\n

The target grade for a residential turf surface is a minimum fall of 1 to 2 percent toward a drainage point. For most backyards, this means the surface should have a gentle slope away from the house and toward a garden bed, drainage strip, or stormwater connection. Before the base goes in is the right time to establish this gradient across the subgrade, making it easier to maintain as the base layers are built up.<\/span><\/p>\n

For sites with known drainage problems, clay-heavy soil, or areas that historically pool, installing perforated drainage coil in a herringbone or grid pattern beneath the base aggregate gives the water an engineered pathway to exit. This adds cost but is far less expensive than addressing drainage failures after installation. Our<\/span> guide to choosing the right turf base for Australian soil types<\/span><\/a> covers drainage engineering in more detail.<\/span><\/p>\n

Step 4: Prepare the Base<\/b><\/h2>\n

With the subgrade excavated and graded, the base materials can go in. The standard approach for a residential installation is a 80 to 100mm layer of compacted crushed rock, topped with a 15 to 20mm layer of crusher dust or fine aggregate for levelling. A geotextile weed membrane is laid over the compacted subgrade before the crushed rock goes in to prevent weed growth from below.<\/span><\/p>\n

Compaction is the most important step in this phase. The crushed rock base needs to be compacted with a plate compactor, making multiple passes in different directions to achieve a uniform, dense surface. A poorly compacted base will continue to settle after the turf is installed, creating undulations that are visible and affect drainage performance. Do not skip or rush this step.<\/span><\/p>\n

The finished base should be firm underfoot, with no soft spots, and level across the full area. Check this with a long straight edge before the turf goes down. Any high spots should be scraped back and any low spots filled and recompacted.<\/span><\/p>\n

Step 5: Choose Your Product and Get Accurate Quotes<\/b><\/h2>\n

With the site preparation picture clear, you are in a better position to choose the right turf product and get meaningful quotes. The product choice depends on how the space will be used: a family backyard with kids and pets has different requirements from a front yard showcase lawn or a side passage. Pile height, fibre weight, and UV warranty are the key specifications to compare.<\/span><\/p>\n

When getting quotes, ask suppliers to break down the cost components separately: excavation and disposal, base materials, turf supply, installation labour, and edging. A line-item quote is far more useful than a single total figure because it shows you where the money is going and helps you compare like for like across different suppliers.
