How To Lay Artificial Grass

Lay Artificial Grass as a replacement to real grass and you can achieve a well-manicured lawn all year round with minimal up keep. This type of grass can be used for a wide range of projects including play areas, pool surrounds and rooftop gardens.

Great for both domestic & commercial properties, artificial grass has several key benefits which cannot be achieved with real grass. Durable and soft to the touch, it has a high UV stability so the colour will not fade and the excellent water permeability means sufficient drainage, whatever the weather.


Picking Your Grass

The type of grass required will depend on what look you want to go for, and will largely be down to personal choice. There are three different lengths available and some might be more suited to specific projects than others. We would recommend;

  • 18mm for smaller projects such as balconies, roof garden and patios. This has a ‘C’ shaped yarn.
  • 25mm for general use including lawns, traffic islands, flat roofs and play areas. The ‘E’ shaped yarn it gives the lawn a plush texture underfoot.
  • 35mm is great again for general use on lawns, traffic islands, flat roofs and play areas, but the longer length gives a more luxurious look and feel. This also has an ‘E’ shaped yarn.

How do I calculate the area coverage that I require? 

All of our artificial grass comes in 2 or 4 metre widths and roll lengths between 4 and 25 metres. This makes it easier than working out square meterage. Choosing the largest size available for the amount you need will be more cost effective than buying multiples of smaller rolls.

What Do I Need?

Artificial Grass
Weed Membrane
Joint Tape
Stiff Brush
Sharp Sand
Sharp Spade
Stanley Knife


Mastic Gun
Turf Cutter

Preparation for a Soil Base

  1. The first step to preparing for installation of your artificial grass is to remove your old turf. A sharp spade is ideal for this, but for larger areas it can be labour intense and a turf cutter may need to be used. Depending on the conditions of your turfed area a depth of 40 to 80mm should be removed.
  2. Once this has been completed use a sharp spade to create a chamfered finished on the lawn’s perimeters.
  3. Using a rake you should remove any lumps and bumps and smooth out the surface of your base.
  4. A stone base must first be laid, to provide a solid base for your artificial lawn. The scalpings will need to be raked flat and then compacted.
  5. A layer of sharp sand should be built up on top of the compacted stone to level off the ground and provide drainage.
  6. Once the sharp sand has been brushed out level, a perimeter edge should be installed. A perimeter edge is always needed to butt grass up where there is no existing or natural perimeter in place, e.g. a brick wall or flower bed. Edging is required as this shapes the artificial grass when laid. The edging spikes will drive straight into the ground
  7. The last step of preparation is for a weed membrane to be installed. Weed membrane is needed for all installations as it prevents weed growth. It also provides additional vertical drainage. The membrane must be trimmed to size during installation and will need to be secured by nails around the perimeter.

Preparation for a Hard Base (tarmac, concrete, decking, etc.)

  1. Clean your surface and make sure it is smooth and clear of debris.
  2. An underlay will need to be laid on top of the existing surface. This will provide a soft, cushioned base for the artificial grass, giving it a more natural feel. It must be trimmed to size during installation.


  1. Before you start laying your artificial grass, you will need to ensure the pile is facing the right direction. Decide where your main viewing point is going to be, your house, patio, decking or gazebo, and ensure the pile is facing this direction.
  2. Lay your artificial grass flat across the areas that you wish to cover. To seam sections of grass together, jointing tape should be used shiny side down with seams laid on top. Glue will then need to be applied using a mastic gun. The pile of the grass will need to face the same direction, and a stiff brush can be used to go over the seams in order to disguise them.
  3. With the grass in place, you now need to trim the perimeters with a flat blade. Follow edges carefully, then fix into place using glue, nailing the edges in at an angle for extra security. You should take care not to cut through any tufts once the grass has been secured.
  4. Once your grass has been fixed into place you now need to undertake the last and final step. You know need to partially sand fill your new artificial grass with kiln dried sand, this should be applied evenly ensuring tufts are spread open if necessary. You should use approximately 6 to 8 kg of sand per square meter of grass. If you brush and blow the sand into the grass, this will help create a natural finish for the surface.

Now all that is left to do is sit back and relax and admire your new lawn…
