Artificial Grass in Wellington

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!

1. Unroll your two pieces of artificial grass, ensuring that the pile is running in the same direction. Fold over each piece by about 300m.
2. To get the perfect seam, cut at least 3 tufts back, ensuring that you don’t trim any grass blades.
3. Either remove the backing on your self-adhesive tape and unroll it down the centre of the join, or roll it out ensuring that the shiny side is down then fix at either end with adhesive.
4. Fold over the grass onto the tape and bring each piece together, ensuring there’s a 2-3mm gap at the seam.
5. Where the pile runs over the edge of the seam, fold over the artificial grass.
6. Apply a small amount of adhesive under the edge of the first section of grass with a mastic gun, then add some to the front edge to stick the second piece.
7. Bring the seam together, ensuring that you don’t get any grass blades stuck. Place a plank with some heavy objects on over the join to ensure that it dries securely.

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!

• Blade material Artificial grass is made up of lots of individual blades, just like real grass. The blades are made of plastic and are sewn to a backing material. To help keep your artificial grass looking great for longer, a blend of blades made from nylon and polyethylene are best. Nylon is extremely resilient, but isn’t very comfy to walk on, so adding the polyethylene which is still very strong helps to keep it feeling nice underfoot.
• Backing material The backing material holds all the artificial grass blades together. It’s made of two layers: a membrane that the grass is attached to, and a section that’s usually made of latex or polyurethane and bonds everything together. When you’re choosing your artificial grass, ask for samples – try to pull away the backing material. If it comes apart easily, steer clear of that type of grass.
• The artificial grass’ use The lifespan of your artificial grass will depend on how much traffic it gets. It’s best to invest in strong nylon or nylon-blend turfs where it’s going to get walked on regularly, such as on a pathway to a door. Of course, if the artificial grass is more ornamental, a lower-quality product will last a long time.
• Good installation One of the main things that will help your artificial grass last a long time is effective installation. If artificial grass is laid badly, it might suffer from poor drainage and weeds which will reduce its lifespan. It’s always best to get your artificial grass installed by a professional since they’re trained in fitting it to a high standard.
