When it comes to such a huge area to landscape, installing artificial grass or even just the workload and time consumption required to plan this process can seem like a daunting task.
Not to worry! Follow these easy and simple 4-step guide for installing artificial lawn and you’ll be looking down proudly at your new awesome backyard in no time. Once completed, Smilingrock would also like to welcome you to the Fake Grass Club!
NO MORE WEEDING! NO MORE MOWING! NO MORE HIGH WATER BILLS!
NO MORE FERTILISING! ULTIMATELY NO MORE SLAVING AWAY!
STEP ONE – EXCAVATION OF EXISTING AREA
Once you have marked out the area for your new synthetic lawn, remove the existing lawn and soil to a depth of 70mm, ready to fill with 60mm of blue metal dust. If prepping for a car traffic area (verge) clear the area to a depth of 100mm ready to fill with 80mm of road base, and 10mm of blue metal dust. If reticulation is present it is simply a matter of capping each pop up sprinkler.
Tip: It is well worth hiring a turf-cutter if you have existing lawn to remove which will save you a considerable amount of time and effort. Don’t forget to hire a skip bin for the disposal of the soil and leftover aggregates.
Calculating the correct amount of aggregate to order is simple.
For example: Total area = 40sqm.
Multiply 40 x 60 = 2400, which calculates to 2.4 cubic metres. The same equation applies to bin size.
STEP TWO – INSTALLING THE BASE
Compacting The Base For Synthetic Lawn. Fill the area with blue metal dust. (Note that it will compact down to 50mm). Carefully screed the area and thoroughly compact it using a vibrating plate compactor. Lightly dampen with water to help bind the dust and this will allow you to see any low areas, which will need to be filled as you go. Compact a second time.
Tip: Spend extra time on the base work as the result will be the difference between an average installation job and a professional installation! Try to give the area some contour and body because an overly flat lawn can look “fake”.
STEP THREE – INSTALLING THE SYNTHETIC LAWN
Synthetic lawn is manufactured with the fibres aligned in a single direction. It is very important to ensure the grain is running in the same direction when laying out the full pieces of lawn. Cut the lawn to the desired shape using a sharp Stanley knife. Invariably there will be joins where the pieces meet. You will need to ensure that the seams are cut as close to the “rib” or “grain” to allow for better placement of the two pieces when joining later.
First, lay the lawn down and cut, leaving about 50mm around all the edges before placing the lawn together so that the joins are not visible. Allow a gap of about 10-20mm between pieces for best results. This can vary slightly from one lawn to another. Stand back and take a look before joining together. Trust your eyes!
Now that you are happy with everything fold back each piece about 400mm and lay the joining tape (silver side facing down) down the centre of the two pieces. Using lawn pins anchor the tape down at each end. Peel off the protection tape and simply place the two pieces back together.
Once done, trim all the edges (Again remember to leave 10-20mm excess), pin around the outside edges 30mm in and 500mm apart. Also pin the joins for extra strength.
Tip: Take care not to trap the blades of lawn under the pins.
STEP FOUR – FILLING WITH WHITE SAND
Great Looking Synthetic LawnBrush the lawn up with a stiff garden broom, brushing against the grain. Spread the washed white sand over the lawn as evenly as possible either by hand or shovel. Aim for a depth of 5-10mm depending on the pile height of the lawn. Brush again to distribute the sand evenly. Job well done!
Tip: The sand infill is so important so don’t compromise. Not only does it improve the look of the lawn but also more importantly it protects the backing from the UV rays.
