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 preparing for a car traffic area (verge) prepare 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.

TipIt 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 disposal of the soil and leftover aggregates.

Calculating the correct amount of aggregate to order is worked out very easily. For example:
Total area = 40sqm.
Multiply 40 x 60=2400 which calculates to 2.4 cubic metres.
The same equation applies to bin size.


Fill the area with blue metal dust noting that it will compact down to 50mm. Carefully screed the area and thoroughly compact 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.

TipSpend extra time on the base work as this will be the difference between an average install and a professional install!
Try to give the area some contour and body because a flat lawn can look "fake".


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 and place the lawn together so that the joins are not visible.

Allow a gap of about 5mm 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, pin around the outside edges 30mm in and 300mm apart. Also pin the joins for extra strength.

TipTake care not to trap the blades of lawn under the pins.


Brush the lawn up with a stiff garden broom, brushing against the grain. Spread the kiln dried 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!

TipThe sand infill is so important so don’t compromise. Not only does it improve the look of the lawn but more importantly it protects the backing from the UV rays.


Installing synthetic lawn is not a particularly difficult job. All that it requires is a keen eye, physical strength and common sense. The DIY process will save you a pocket full of money but, if you are in doubt contact us to arrange for a professional to expertly take care of it for you.
