Below is a technical overview for SytheTurf, an artificial, sand filled grass surface. To find out more information on synthetic grass and other safety surfaces, please click one of the links above.
SyntheTurf artificial grass consists of a 28mm high polypropylene pile synthetic turf woven onto a perforated laytex backing. The pile is filled with dried sand to within 15mm of the top of the carpet.
To aid longevity and to provide drainage, as well as helping to prevent settlement, we recommend that a sub base is installed below the syntheturf carpet. The depth of the sub base will vary according to ground conditions concrete. In most cases, however, a 50mm depth of compacted sub base material (frequently MOT1), laid onto a geotextile membrane, is sufficient. This should be dressed with a 25mm layer of grit sand in order to provide a flat, level finished carpet surface.
We prefer to raise the finished surface level very slightly above the surrounding levels in order to improve drainage.
Edging details will vary according to the site conditions and requirements. See the following technical drawings for our recommendations
Artificial grass laid into an existing natural grass area, with perimeter covered by natural grass
The perimeter of the carpet can be buried underneath the surrounding turf. It is pinned into place, at 1.0m centres, before the soil and grass are placed over the edge of the carpet
Artificial grass laid into an existing natural grass area, with perimeter fixed to a concrete kerb / brick edge
Artificial grass laid into an existing natural grass area, with perimeter fixed to timber edge
Synthetic turf laid onto existing tarmac
Synthetic turf can be laid directly onto an existing tarmac or concrete area assuming that a good perimeter fixing can be achieved (ie the tarmac is in good condition and is not fretting). A ‘chase’ is cut into the perimeter into which the carpet is tucked. The carpet is adhered into the chase using an appropriate adhesive.
If the tarmac is liable to holding water during and after rainfall, it may be necessary to drill drainage holes through the tarmac to aid the removal of standing water.
Our fake grass has also been tested to BS4790 for fire retardency and to DIN5400 for colour fastness.
