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!
