Laying Instructions for Artificial Grass

  1. Remove existing surface (lawn or soil) to a depth of 100mm. Level and compact the surface. It may help to hire a whacker plate/compactor to complete this task. In cases where the existing ground does not drain well, it may be worth considering digging out further to aid drainage.
  2. Batten out the area to be covered with pressure treated (tantalised) timber to create a frame. The purpose of the frame is to help contain the aggregate, but also to provide a secure frame onto which the grass can be fixed using galvanised screws.
  3. At this stage, you can either simply ‘weed kill’ the area, or, alternatively, install a good quality weed suppressing membrane to help prevent any future weed growth. You can either fix the membrane to the side of the frame, or allow the weight of the aggregate and sand layers to keep the membrane in place.
  4. Apply a good quality fine aggregate to a depth of between 25-75mm and level and compact again. Apply a further layer of sharp sand to a depth of 25mm, and level and compact again.
  5. Once the aggregate/sand sub base is level with the top of the battened frame, lay the grass in place and trim to fit, where necessary. Use a sharp knive and cut from underneath. Trim back gradually until the required size is achieved.
  6. Screw the grass to the timber frame, using galvanised screws.


You can apply a top dressing of kiln-dried sand (See our Aggregates/Sands page), which is readily available from builders merchants. Whilst optional, the sand helps to hold the grass in position as well as maintaining the pile upright. If using, simply add the sand evenly over the grass and working against the pile, using a stiff brush.
