Decrease the maintenance and increase the look of your outdoor area with ease.

It’s no surprise that people look for a lower maintenance alternative to real grass. Learning how to lay artificial turf avoids you needing to deal with a lawn that can be tough to grow and keep healthy with regular mowing, weeding and watering. A green garden with no hassle seems like a pretty attractive prospect when you take all of that into account.

Luckily, synthetic grass has improved significantly, not only just in look but also ease-of-installation. Available in tiles and rolls, it offers a range of applications to provide you with a no-mow lawn that looks like the real thing.

Read on for everything you need to know about how to lay synthetic turf with this handy step-by-step process, and you’ll have a garden that looks great all year round, with little effort required in no time.

Step 1: Excavation

First, you need to excavate the area you are planning on laying your synthetic grass on. Clear all of the weeds, rocks and debris and set out a perimeter of string lines to the desired height. Excavate the soil until you reach a depth of 75mm, which is about as high as a standard house brick if you need a handy gauge.

Step 2: Compact

You’ll need to compact your base which can be done by laying weed mat. Ensure you have an overlap of around 50mm to ensure its efficiency. Spray the area with water then firm down the base using a plate compactor.

Step 3: Laying the turf

Before you lay the actual turf, spread a thin layer of fine sand and level it with a rake. Measure and cut your first piece of turf but be sure to leave an extra 50mm. Lay it in position and repeat these steps for the remaining pieces.

Step 4: Joining the pieces

Peel off half of the protective backing and attach a roll of turf tape. Only peel about 600mm of the backing at a time and join the two edges, pressing down firmly to ensure it is all secure.

Step 5: Trimming the edges

With a sharpened utility knife, carefully cut around the borders in small sections. It is always best to cut from the underside of the turf.

Step 6: Securing the grass

Use turf pins around the perimeter and across the joints at 300mm spacings with 600mm across the centre. This will make sure your new turf is secure. Finally, brush some fine, dry sand against the grain.

How to lay artificial turf on concrete

The beauty of synthetic grass is that it can be installed on most surfaces, including concrete. If you are looking at giving some colour to your outdoor concrete areas, follow these steps.

Step 1: Inspect the area for drainage

First, you want to ensure there are no drainage issues in the concrete area you are adding synthetic turf to. Clean the surface, so there are no rocks or debris and make sure the surface is level.

If you need to, you can apply drainage cell squares to increase the drainage capabilities of your space. To do this, place the drainage cell plastic squares sporadically around the area to encourage air and moisture to flow underneath the grass. This is a particularly good idea if you have pets.

Step 2: Measure

Before you purchase synthetic grass, measure the length and the width of your surface area to determine how much you need. When you get your synthetic grass, cut it into the lengths you require.

Step 3: Secure to the concrete surface

Position the synthetic grass over your concreted area, and apply by peeling back the double-sided adhesive tape or using the glue (depending on which option comes with your type of grass).

Double-sided adhesive tape is the cleanest and most efficient option as you only need to peel away the tape’s top plastic layer, then stick down the synthetic grass edges to secure. If using an adhesive glue, which may be better if you are securing to exposed aggregate, glue with a 4mm notch trowel around the perimeter. Stick the edges and add some glue down the middle for extra hold.

Step 4: Brush and apply sand infills

Brush the grass to help it stand, then apply sand over the top and brush it in thoroughly.

How to lay artificial grass on sand

It is actually recommended that you lay your synthetic grass on a 35mm layer of compacted sharp sand. While this is not crucial if you already have a sanded area that you wish to cover with synthetic grass, you can for a great result!

Step 1: Compact the ground

Make sure the ground is even and compacted by using the back of a shovel for small areas or a vibrating plate compactor for bigger ones. Lay a weed membrane to stop seeds from germinating in the sand. Overlap the membrane by around 50mm and go right to the edge of your area.

Step 2: Lay the artificial grass

Allow approximately 50mm of extra artificial grass so you can trim to make the perfect edge. Butt the grass edges together, peel back the adhesive and secure the sheets in place. Push down on the sheets to ensure the adhesive takes, you should not need to do this for more than a minute.

Step 3: Trimming

Cut and trim your sheets using a sharp knife, and ensure there are no gaps, especially between any walls and your grass. Never rip the grass and always use sharp blades when cutting. If your synthetic grass has a material trim on one of its edges, make sure you remove it before laying.

Step 4: Fixing

Use some ground pins and nail them into the ground at an angle roughly every 200mm to secure the perimeter of your newly grassed area. This will add some extra security and ensure your slabs don’t move or shift as people walk on them.

If you want even more security, you can add extra ground pins through the centre. Just ensure they are flush to prevent a trip hazard. While you can never have too many, there is no need to go overboard.

Frequently asked questions

What do you put under artificial grass?

This really depends on the surface that you are laying your artificial grass on. If, for example, you are laying it over dirt or sane, you should compact and level the ground then lay a weed mat under your grass. This not only gives you a surface that you can secure your mats to but lowers the amount of maintenance you will need to do by preventing weeds from popping up to the surface.

If you are laying your grass on a concreted area, simply ensure it is clean and capable of drainage, and you are good to go!

How do you prepare the ground for artificial grass?

It is important that any surface you look to lay artificial grass on is free of weeds, rocks and debris, as well as being as compact and level as possible. In cases where you are laying your grass on soil or sand, a weed mat will be required. This will protect both the ground below your mat from seedlings that can germinate in the sand, as well as the surface of your grass by preventing weeds from pushing through.

It is also a good idea to keep your base as level as possible and ensure there are no lumps in your grass after you have laid it. This not only looks much more professional but also means no one will trip on your new flooring.

Can you lay artificial grass directly on soil?

Yes and no, you will need to prepare the area and lay a weed mat in between the soil and grass. This not only gives you something to secure your grass slabs to but protects the surface and undersoil of your grass, while also lowering your maintenance time.

It is not recommended that you attempt to attach your grass slabs directly to the soil as it will not be as secure. If you do this, you will likely find yourself needing to re-set your synthetic grass sooner that you would like.
