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.

Soil and sand


For a sand base, it is recommended that you place your artificial turf on a 35mm layer of builder’s sand. For a soil base, make sure you remove 35mm of any vegetable topsoil before you lay down the new turf, as this will result in an uneven decomposition.

The soil or builder’s sand should be levelled and spread evenly. If the area experiences poor drainage, place a stone slab underlay so the turf doesn’t absorb all the excess water. A weed control fabric should then be laid on top of the sand or soil to prevent any seeds embedding into the base.

Laying the turf

Place the artificial grass on top of the weed control fabric, ensuring it overlaps the joins by at least 100mm. To prevent any rippling, leave the turf to settle for a day or two so it gets used to the weed control fabric underneath.

Join the edges together with the direction of the grass facing the same way before peeling the grass back. Next, cut and trim your turf with a sharp knife before nailing it into the ground.



Ensure that the concrete surface is smooth and not dirty. Check the level of the surface for any unevenness and smooth out any bumps, as these can been seen through thinner layers of artificial grass. If there is poor drainage, make a few holes in the concrete or place foam under the surface to keep the grass above the surface.

Laying the turf

To cushion the concrete base, do a loose lay of under felt 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.

Wooden decking


Roll out the artificial grass and trim as required; placing it on the decking surface means the turf will remain flat from its own weight. Put heavy objects such as plant pots around the edges to hold it still during strong winds.

Laying the turf

Similar to the concrete base turfing, lay a 12mm under felt underneath the grass to cushion it and join and trim the grass. You can use an outside adhesive to fix the grass to the decking, or can use an industrial stapler to affix it to the wood instead.



Extra protection should be implemented when turfing roofs. There should be a 12mm foam underlay put over the existing roof first, to both protect the roof and allow for a good drainage.

Laying the turf

As roofs can come in a multitude of different surface types, the roof fitting method needs to be done by professionals so as not to damage anything.
