How To Lay Artificial Grass : The Complete Guide

Artificial grass, lawn, astroturf or whatever you may call it isn’t always simple to install, which is why we recommend using a professional installer to lay artificial grass for you. However, if you find yourself scratching your head and thinking “how do I lay artificial grass?”, then this is the guide for you. 

Tools Required To Lay Artificial Grass

Unfortunately, laying artificial grass isn’t as simple as just laying the astro turf down. However, the following tools will make the installing artificial grass a whole lot easier:

Edging Option (as opposed to using nails):

Artificial Grass Bases

What do you put under artificial grass?

To perfectly lay your artificial grass onto an existing hard base such as concrete or tarmac, we recommend installing a layer of Lazy Foam underlay beneath the artificial grass.

Before you lay the foam pad down, be sure to clean the surface beneath it. The foam underlay padding will provide extra cushioning and drainage to ensure your artificial grass is of a great standard all year round.

Can I lay artificial grass on soil?

Unfortunately, laying your artificial grass down directly on a soil base is not recommended. This is because soil can become a victim of weather-induced wear and tear quite easily – leaving you with a base that is compromised.

Ultimately, this will ruin your artificial grass, so it is imperative to lay your artificial grass on a stronger base – a combination of MOT type 1 and granite stone 6mm dust.

Can I lay artificial grass on concrete?

Artificial grass can be laid on top of concrete as long as it is even and is able to drain water correctly.

However, regardless of whether the concrete is even or not, we recommend using an underlay to properly make sure your artificial grass is looked after in the best way possible.

Can I lay artificial grass on decking?

The short answer is yes. However, as with concrete, you need to take the right precautions before doing so. You must make sure the wood is strong and fresh – not weak and/or mouldy.

When installing artificial grass on decking, you must also be sure to use some sort of underlay and weed membrane to make sure your artificial grass remains in tip-top shape.

How To Install Artificial Grass

To keep things simple, you can lay artificial grass by using the required tools listed above and by following our 6 easy steps below:

1. Plan and clear the area

2. Create an edge

3. Lay the base

4. Apply weed membrane

5. Lay the artificial grass and trim edges

6. Add finishing touches

Read on below for information on each step and learn how to install artificial grass.


Step One: Plan & Clear the Area

Before starting your project, plan out the area to be covered. Ensure that cables and water pipes are below the digging depth.

Remove the turf to a depth of 2″ using a turf cutter or spade and remove any large stones, bricks, or other obstructions. Lay down a type 1 stone base.

Step Two: Create an Edge

If there are no perimeters for the product to butt up against, install an edging system. We recommend securing your artificial turf using VertEdge. Knock the edging into the soil with a hammer and a piece of wood, leaving around 3cm exposed. 

Step Three: Lay the Base

Apply around 6mm of granite dust. Use a piece of timber to drag the sand or dust across the application area to provide a smooth surface. If using sand, the depth should not be more than 20mm. Use hardcore to level out larger imperfections (i.e. over 20mm) before applying sand.

Step Four: Apply Weed Membrane

Once the base is compacted, apply a weed membrane to the area and secure it in position with 6″ galvanised steel nails every 0.75m around the perimeter. This will prevent weed growth whilst allowing water drainage.

Trim off any waste membrane from the edges. If any joining is needed, overlap the edges then attach them with gaffer tape.

Step Five: Lay the Artificial Grass & Trim Edges

Unroll the artificial turf over the area, being careful to not move the weed membrane. Having the pile direction running toward the house will give the best look from the windows of the house.

Once positioned, trim the excess artificial grass. VertEdge gives you a useful edge to run your knife around. We recommend changing blades every 3-5 metres to ensure the blade stays sharp enough.

Step Six: Add Finishing Touches

To finish, apply kiln sand to the turf. This can be done using a blower and stiff brush or a lawn fertiliser spreader. We recommend 6-8kg of sand per square metre of product. This step is vital to ensure the most natural-looking finish.

For the best results, we recommend brushing the pile before, during and after. This sand infill dressing should be done on a dry day and the same day as the lawn installation.
