When it comes to installing your synthetic Artificial Grass or Artificial Lawn it is really best done in the hands of professional fitters/installers who can measure the area to be fitted, supply the turf for you and then install it for you. This article is meant as a general guide for those people who feel competant enough to lay their own artificial grass.
First, the area needs to be cleared of all weeds and grass – this may take some time as after the first round is done you may want to wait and check for any regrowth that needs to be sprayed. Once you are certain everything is dead it is a good idea to clear it all away, along with any big rocks or debris.
Next you will want to level and compact the cleared site. A light water followed by a vibrating plate compactor should create a nice solid, firm surface. It is important to consider drainage – synthetic artificial grass will not absorb water, rather the water will run off like it would on concrete. Angling the surface slightly away from your house should be enough to prevent any pools forming on the surface.
The base is comprised of various layers, first the earth, then fine stones then, if necessary, a layer of sand to add softness. Once the earth layer is completely dry and compacted the 5mm crushed rocks or crusher dust may be added and similarly compacted. The thickness of this stone layer will vary depending on the stability of the soil where you live.
A fine layer of sand can then be added to make the surface completely level and ensure that the stones won’t be felt through the synthetic turf.
At this point you should also check for any depressions in the base surface. Anything that is deeper than 10-20mm should be filled in and that area levelled again.
Start by rolling out the turf and positioning it where you would like it to be. This is very similar to laying carpet. Once the turf is positioned exactly where it needs to be you can trim the edges using a sharp knife. Be careful to ensure that the turf sits neatly on your prepared sub base.
The pieces of turf are now seamed together. Two edges of turf are glued together with a special outdoor turf adhesive and then joined with wide seaming tape.
Now the artifcial grass needs infilling. The intention of infilling is to weigh down the grass to help secure the fibres so as to avoid matting. Thin layers of granulated rubber and sand are applied in four stages, using a fertiliser or drop spreader. After each layer is spread it should be swept with a broom or lightly raked, ensuring the infill has been pushed down to the bottom of the grass.
It will take around 2 months for the infilling to completely work its way down into the fibres. Once the grass has been laid, it will not need mowing or watering and is best cared for by brushing occasionally with a soft bristled brush. Heavy brushing is not necessary and can have a damaging effect.
