Once you have completed the preparation stage which includes measuring how much artificial grass you need, installing appropriate drainage (if necessary) and removing the natural grass layer, you will be ready to install your artificial grass lawn. This article outlines the steps you should follow to help you to get the job done right, from laying the base, connecting joints and preventing weed growth.
Lay Gravel Base followed by Sharp Sand
If required, use treated timber/timber stakes to put in an area frame Synlawn. We recommend 4 X 2 inches of tantalised treated timber for heavy clay soil areas and poorly draining areas and 2 X 2 inches of tantalised timber for good draining areas. Screw these timbers to the stakes leaving the stakes on the inside of the perimeter. Should the Artificial Grass meet a concrete path, wall or decking, position the timber flush with the surface height and by using 10mm temporary fillet, pack the timber close to the wall leaving the space to enable you to tuck the Artificial Grass between the timber and the adjoining material at a later stage.
Position the stakes against the inner perimeter timber edging and hammer in to the ground ensuring the stakes are slightly lower than the timber edging. Next screw the timber stake to the timber edging.
With heavy clay soils we recommend laying a crushed stone surface of up to 3 inches. This will not be necessary for the majority of areas and only required if you have a high water table where the ground holds water for a long period of time after it rains. Next compact the ground using a vibrating plate that can be hired from an equipment hire company. Ensure the perimeter is compacted and below the timber edging by 1 inch. Infill the perimeter with sharp sand and level using a rake. Ensure the sand is level to the top of the timber edging and compact again.
For good drainage areas spread a layer of sharp sand to blind over the soil. Next compact the ground using a vibrating plate that can be hired from an equipment hire company. Ensure the perimeter is compacted and level with the timber edging.
If you put more work in at this stage, your Artificial Grass Lawn will look better as a result.
Weed Control Layer
Apply the weed control geo textile membrane and cut as necessary. Tack using small 1 inch galvanised clout nails to the timber edging. This weed control geo textile membrane prevents any chance of weed growth through the artificial grass drainage holes.
Roll out Artificial Grass
Lay the Artificial Grass in the desired direction working on the carpet and not on the levelled base. Ensure the carpet is positioned to minimise cuts, joints and waste overlaying the timber edging by a minimum of 4 inches. If the artificial grass meets a path or edge, and if you have laid the timber edging correctly as previously described, then the artificial grass can be wedged between. If joining, please ensure that the artificial grass is laid with the pile running in the same direction on each piece. Lay the carpet on top of the sand as opposed to dragging it across the base material. To help stop wrinkles or creasing it is advisable to allow 2 to 3 hours to settle before continuing with jointing and adhesive. Cut grass to shape using a sharp Dolphin or Stanley knife or scissors.
