Artificial Grass in Gwynedd

Laying artificial grass is a popular project – it’s a great way to create a smart, low-maintenance garden. There are plenty of professionals around who are experts at installing artificial grass, but it’s possible to DIY too if you’re feeling confident.

Lots of homeowners choose to replace their existing turf with artificial grass, so lay it on soil. To do this, start by clearing the area of any greenery or turf. Then remove any extra soil to a depth of about 40mm. You might want to leave the centre of your area slightly higher than the edges for a more natural look.

Next, you need to add a weed membrane and a sharp sand sub-base. It doesn’t really matter which one of these you do first, but you might find it easier to lay the weed membrane first and then use the sand to weigh it down, to a depth of about 35mm. Use a rake and plank to make the sand level, and compact it with a plank and heavy hammer. It doesn’t need to be completely flat – gentle slopes are fine. The weed membrane should overlap joints by 300mm.

After you’ve done this, you can lay your grass. Roll it out, trim it to size and fasten it in place. Make sure the ends of the grass rolls are staggered so they don’t end in a line. Lay the artificial grass with the pile (the strands) leaning towards the house so it looks nice and full when you’re looking out from the house. If you’ve decided to use edging boards, you can nail the grass into the tops of the boards. Or, if you haven’t, use ground pins to anchor it into the soil. Brush the grass and you’re done!

Laying artificial grass on concrete needs a slightly different approach to if you’re installing it over soil. The good news is that it’s much less labour intensive, as you don’t need to do any digging or levelling.

Ideally, your concrete base should be in good condition, and have an adequate fall on it to provide efficient drainage. If it doesn’t, you might have to do some repair work or drill some drainage holes first.

When you’re ready to start, begin by cleaning your concrete base. Use a jet wash or a hose and brush to dislodge and disperse any dirt or plant growth. Once it’s clean, leave it to dry completely.

Then, you need to fit an underlay - usually it’s made of foam. This will provide padding to make your artificial grass softer and more comfortable to walk on. It will also help to level out any slopes on uneven parts on the concrete. Make sure it’s a good-quality underlay that’s permeable – if it’s not, you could end up with damp artificial grass and nasty smells as it will hold moisture. Roll out the underlay and cut it to shape, taping any separate sections together.

Next, use an adhesive to secure the underlay to your concrete. Make sure you leave gaps in the adhesive to allow water to drain off easily. Leave the glue to dry, then you can start laying your grass.

Roll out your grass like you did with your underlay, cutting it to shape and joining any separate sections together with artificial grass tape. Then glue the grass to the underlay. Leave it dry, give the grass a brush, and it’ll be ready to use!
