If you lay synthetic turf on top of an unstable surface it can shift over time and the surface can become uneven. The look and stability of your grass over its lifetime is reliant on a suitably prepared sub base. Installing a fake lawn is a large investment so it’s important that it’s done properly.
Artificial grass is extremely versatile and can be laid on a wide variety of surfaces, from existing lawn area to wooden decking and hard surfaces. So if you’ve been wondering what to put under your artificial grass, below are the most commons bases and application methods.
Always recommended where natural turf is being replaced
Type 1 MOT and a suitable blinding surface, such as sharp sand or granite dust, provide a stable, porous base which is ideal for artificial grass. Depending on the sub soil and drainage in the area, you should lay 50 to 100mm of Type 1 MOT, thoroughly compacted, and apply a top surface of 10 to 15mm of sharp sand or granite dust. The area can be edged with timber, composite battening or a concrete haunch.

Ensure that the decking is stable, clean, dry and newly treated.
Timber decking can provide a suitable base for synthetic grass but be careful to use a 10mm foam underlay to take up the 'gaps' between the slats, in order to avoid the grass being pushed down into the gaps. You'll see marks appear in the grass over time. Our 10mm Play Pad will provide a suitable underlay for the grass and also assist with drainage between the grass and the decking. Hard Surfaces - Patio Areas and Concrete
Ensure that the area is smooth, dry and clean. Check for any unevenness and smooth out any bumps, as these will be seen through the artificial grass over time. Our 10mm Play Pad is an excellent product to help provide a smoother surface and can be laid and fixed by simply applying a bead of glue around the perimeter of the area and adhering the underlay to it.
If there is poor drainage, make a few holes in the hard surface.
Once the 10mm Play Pad has been installed just trim the synthetic grass to the required shape and size, run a bead of glue around the top surface of the underlay and then apply the grass.
Roof Terraces and Balconies
Ensure roof is stable, clean and dry. Apply 10mm Play Pad to provide cushioning, take up any unevenness and assist with drainage. Glue the underlay down with a bead of glue around the perimeter and fixing the grass to the underlay using the same method.
