Installing artificial grass correctly is essential to ensure that in the end your lawn looks fantastic. If you’re opting to install your artificial grass yourself then we recommend following the process we’ve detailed below, however, for the best results you can choose our experienced team of fitters.
Getting Started
The first step in the preparation process is to measure your garden and plan how much artificial grass is needed, as well as membrane and jointing materials. At this stage it’s important to calculate how much type 1 aggregate and crushed dust will be required to form the base. Being able to accurately calculate how much material will be needed can keep the project cost effective and save needless waste.
Digging Out
This is one of the most physically demanding parts of the project, it is essential it is done properly. Having the right tools, such as a turf cutter, makes the process much easier than just using a spade. First of all the top layer of turf and any weeds will be removed, then soil will be removed to establish the right levels for the base material to go in. Topsoil can be re-used, particularly if you’re also having planters built in the garden renovation process.
Framing the Area
At this stage the edges of the area in which the artificial grass is going in to can be framed out. This can be done with timber, or in some cases a concrete haunch.
Geotextile Membrane Layer
This layer is very important if you want to minimise the chance of weeds emerging. This layer can be positioned above or below the sub-base layer, we favour putting it below. Laying the membrane is a fairly simple process, just roll it out over the required area and overlap sections if the roll doesn’t cover the entire area. Some type 1 aggregate can be used to prevent the membrane blowing away.
Type 1 Aggregate Layer
This layer is important for creating a strong, compact base that won’t sink and become uneven over time, as well as for drainage to prevent puddles and flooding. At the dig-out stage the depth will have been decided with the aggregate sub-base in mind, we recommend at least 40mm of type 1 aggregate so that it can bind and become solid when compacted with a wacker plate.
Granite Dust Layer
On top of the type 1 aggregate another layer of finer crushed granite dust will be added to create a smooth finish at the top of your sub-base. This will need to be compacted with a wacker plate to bind it with the layer below and ensure the levels are correct.
Installing the Artificial Grass
It’s important to lay artificial grass in such a way that minimises wastage and results in the fewest cuts. Also, if you are going to require more than one piece, ensure that the artificial grass is laid with the pile running in the same direction. If there are any creases in the roll of artificial grass then these should disappear in anything from 1 day to a week, this process is quicker in warmer weather.
Other Installation Questions
Can I just lay artificial grass on soil?
We don’t recommend this at all as artificial grass has to be installed on a solid sub-base.
Do you need drainage under artificial grass?
Yes, otherwise your garden will flood when it rains. All of the materials we use are porous, meaning water can drain freely.
Do you put gravel under artificial grass?
Certain types of gravel are used in the sub-base of artificial grass to provide a stable foundation when compacted, on top of which a finer layer of crushed gravel dust is also compacted.
Do you have to put sand on top of artificial grass?
Sand is not necessary, nor is it a good idea on top of artificial grass as it encourages weed growth.
How deep to dig for artificial grass?
The depth of the dig-out that precedes the laying of artificial grass depends on a number of factors to ensure a successful installation however a minimum of 100mm is required, in some cases you may need to dig deeper until firm ground is met.
Can I just use sand under artificial grass?
Sand alone is not a sufficient sub-base for artificial grass. A sturdy sub-base requires larger gravel and crushed gravel to be used.
Do you need to dig up grass before laying artificial grass?
We recommend a full dig out of an area, including grass, and creating a solid sub-base before installing artificial grass.
