How to Lay Artificial Grass

How to Lay Synthetic Grass

Step 1 - Area layout, grass ordering & stripping the existing material

Using a rope or garden hose as your proposed border, layout the area in which you want to install your synthetic lawn. Try several different locations at different times of the day to be sure you choose the one that best suits your needs. Choose any design you like, but remember that synthetic turf arrives in rolls at approx 3.7m widths.

This may also be the time to change the contour of your yard. Be sure to allow for drainage, run-off, wet or shady areas, etc... when laying out your yard. Only a small amount of water will drain through the grass as most of it will drain “off” like it would from pavers or a concrete slab.

Ensure you order the correct amount of grass, backing tape and glue. Map out the area to scale on graph paper. (Remember the synthetic grass rolls are approx 3.7m wide). Map out the grass pieces you will need over your sketch to scale and make sure the grass is all laying in the same direction. For example if you have a piece left over that will fit into an area, the fibres of the grass on the roll will have a "direction" to them, and all the pieces must lay in the same direction as the rest of the grass. You are essentially working out how many lineal metres of grass you will need to cover your area.

Remove all the vegetation and other debris down to the bare earth. Rotting grass today may cause unwanted dips tomorrow. Sprinklers may be capped or removed at this time.

Step 2 - Installing dolomite base, compacting and optional edging

It is recommended that you install the synthetic turf on a compacted dolomite base or on an existing concrete slab. Depending on your existing sub base, a minimum of 50mm of dolomite (after compaction) is recommended. In sandy or clay conditions, you may wish to use a thicker base. If you are in doubt, please consult your local landscape yard or landscape architect for base materials recommended for your area.

dolomite installationCare should be taken to choose a material that is free of large stones and should be graded and compacted to as smooth a finish as possible. The product should be composed primarily of crushed stone, with enough fine sand to assure compaction and stability. Be sure to compact the base several times and dampen the dolomite prior to packing.  Dolomite has a high salt content which will assist in reducing weed growth.

 

Dolomite compactingPlate compactors and additional tools can usually be hired by the day. Remember - your goal is to make the base as hard as possible. You should compact the base at least twice and don’t forget to make sure you have enough fall on the base to allow water to drain.You may wish to install optional edging. Consider brick, decorative or natural stone, timber, flexible plastic or metal edging (ie. Link Edge). The top of the edging should be at the proposed finished elevation of the base to prevent trapping water.

Step 3 - Lay out your Enduroturf Synthetic Lawn

Once the base work is completed, roll out the turf AWAY from the site and cut to length as needed 1 piece at a time. Make sure that where multiple pieces of turf are being used, they are laid with the pile pointing in the same direction. Cut turf to fit where necessary. This can be done with a sharp utility knife and a new blade.

Cutting synthetic turfCut the turf to fit around trees, flowerbeds and landscape islands, etc... If you change your mind at this point or make a mistake, don't worry. Simply use the seaming method described below to put turf together where you want it.

In areas larger than 3.7m in width, where two pieces of synthetic turf must be seamed together, you will need to ensure you have ordered seaming tape and outdoor quality seaming glue. It should be noted that turf joined together using the correct method should look seamless. Once you have finished laying out your turf, step back and survey the landscape. Be sure your turf is in the right placement. If you find that your layout isn't right, change it now before commencing with the joining method described below.

 

Step 4 - Synthetic Lawn seaming method

Seaming synthetic turfIf a join is required butt both synthetic grass surfaces together ensuring the pile is running in the same direction, then fold back each side approx 30-40cm along the length of the join. Unroll the join tape along the join line on the ground, ensuring equal tape on each section. Apply the adhesive along the joining tape approx 20cm width. Fold over one side of the artificial grass on to the join tape. Then start to fold over the second side, ensuring no tufts of grass are crushed under the join and keeping the join tight together. Once complete, it is a good idea to weigh down the join with bags of sand to ensure it sticks. Most glues should take in approx 30 minutes.

 

 

Step 5 - Install the sweeping sand

Now it's time to install the sweeping sand. Different grass types require different infill levels, most Enduroturf products do not require rubber so check first.

Your first job is to gently spread sand across the entire area. Typically this sand is “thrown/sprinkled or lightly spread” across the area as evenly as you can. You are aiming to infill approx 1/3 of the pile height with sand. After spreading with a shovel, you will need to broom against the grain to allow sand to fall between the blades of grass. Make sure you keep the grass fibres upright during this process. You will need a stiff bristled 'street' broom.

Sweeping sand installationTake your time - Make sure you do not simply “dump” sand in any one spot as you will crush the grass fibres down and then getting the sand in and the turf back up is very challenging.

This process will take 2 or 3 attempts to get levels right. DO NOT try to spread the sand all in one go.  The fill you install today is going to compact somewhat with rain and use over time.

And that is it. You should now be the proud owner of the nicest lawn on the block. What you will need to complete the job: o @6kg dry sand per sq.

What you will need to complete the job:

  • approx 6kg dry sweeping sand per sq. metre
  • Stanley knife with a NEW blade
  • Shovel
  • Rake
  • Stiff-bristled “street” broom
  • Spirit level
  • Screed
  • Wheelbarrow

Additional items you may need to complete the job:

  • Plate compactor (hire from Kennards or similar)
  • Turf cutter
  • Dingo/mini dingo
  • Skip bin
