How to lay artificial grass

Artificial grass is a great way to ensure that your garden stays bright during all seasons of the year. The process of laying this grass is rather simple. The main steps involved include clearing the garden, rolling the grass out and tidying up the edges. You will need to clear your garden or the area where the grass is to be laid, digging out the area to a depth of roughly 100mm, preparation of the base material and a layer for protection against weeds. Then, you roll the artificial grass out, cutting and tidying the edges and then joining the rolls together and you’re through. Here are the steps in more detail:


Step 1: clear the area

If you’re replacing natural grass with artificial grass, you should begin by digging your turf to about a 100mm depth using a turf cutter or a spade. The reason for doing this is to make sure that your finished grass doesn’t stand unsightly taller than the pavement in the area surrounding it. If you’re edging the area, a tantalised timber frame is what to use. Then, use timber batons or concrete restraint or edging block to secure it.

Step 2: prepare the base

For better drainage and a solid foundation for laying the artificial turf, it’s advisable to use a sub-base of the MOT type 1 grade. Don’t forget the geotextile membrane below to ensure the sub-base from sinking into the soil under it. With a compactor plate, compact the sub-base in two layers. This compaction should be done to a 70-75mm depth.

Step 3: level off

By using a sand spreader or shovel, spread the sand layer to about a depth of 20mm. Then evenly smooth the sand out across the sub-base and then press it down with either a hammer and a plank or compactor. Ensure the surface is level.

Step 4: weed out

Over the sub-base; roll out weed membrane sheets to serve as a layer for bedding. Then between sheets, there needs to be an overlap of weed membrane sheets which should be around 30cm.

Step 5: roll the lawn out

The next step in the process is to roll out the artificial grass ensuring that the pile faces towards your direction. Alternatively, it should face the main viewpoint and allows an extra 5 cm of grass on all the sides. Avoid trying to exactly line up the rolls ends.

Step 6: cut and tidy

Once you’ve unrolled your turf, use a knife to trim away the rough edges from the turf rolls. Nothing should be showing up from the underneath.

Step 7: glue together

Using a Stanley knife, remove two to five rows of stitches from the adjoining grass rolls. Fold these edges back and lay a jointing tape ensuring that shiny side is face down. Ensure that each grass roll has no less than 5cm of adhesive contacting the tape.

Step 8: pin down

In case you’re using a frame of timber, make the grass secure to it using screws every 150mm to 200mm. Alternatively, you could glue your grass to the horizontal haunch of concrete of the hedging block. Otherwise, you can use a hammer to knock into the ground pins at a spacing of 20cm to 30 cm. To disguise the appearance of your pins, you can brush the edges.

Step 9: sweep the artificial turf

When the glue is dry you can use a broom to sweep the surface off for casting out lose grass blades, dirt and dust.
