Artificial grass is extremely versatile and can be laid on a wide variety of surfaces, from soil to wooden deckings and concrete. So if you’ve been wondering what to put under your artificial grass, below are the most commons bases and application methods.



For a soil base a suitable sub base is recommended – you should always install you artificial turf on an aggregate and sharp sand base. Make sure you remove 60-80mm of soil before you lay down the sub base and new artificial turf, as this will result in a perfect installation.

Guide to installing artificial grass

Laying the turf

Place the artificial grass on top of the weed membrane, join and trim as per installation guide.



Ensure that the concrete surface is smooth, dry and clean. Check the level of the surface for any unevenness and smooth out any bumps, as these can been seen through the artificial grass. If there is poor drainage, make a few holes in the concrete  and for extra comfort foam pad can be installed below the grass.

Laying the turf

To cushion the concrete base, a layer of Perfectly Green foam pad can be installed under the artificial turf. As mentioned previously, make sure the edges are joined together and the grass blades face the same direction. You can glue the concrete base and turf together with outdoor adhesive. Fit the artificial grass over the foam pad and where multiple grass sections are fitted join them together as per our installation guide. Foam pad can be part glued to the concrete around the perimeter leaving the occasional gap for drainage. Glue artificial grass to to the foam pad around the perimeter.

Wooden decking


Ensure that the decking is stable, clean, dry and newly treated.

Laying the turf

Fitting a Perfectly Green foam pad is recommended when installation artificial grass on decking. This will prevent the artificial grass from compressing into the gaps between the decking slats. Screw the foam pad into the decking around the perimeter, install the artificial grass as shown in our guide and screw the grass into the decking through the foam pad. Do not screw down too tightly as this will pinch the artificial grass.



Ensure roof is stable, clean and dry.

Laying the turf

Extra protection should be implemented when turfing roofs. There should be a 10mm foam underlay put over the existing roof first, to both protect the roof and allow for a good drainage. We recommend the 10mm foam pad which you can see here Safety Play Pad System

Part glue the foam pad around the edge leaving occasional gaps for draining and then install the artificial grass on the foam pad gluing around the perimeter.
