The synthetic fibres incorporated into the rootzone make the grass stronger and more resistant to damage.
Grass roots were allowed to intertwine with a mix of soil and synthetic fibres as they grew.
[6] Three main methods exist to insert synthetic fibres in the root zone.
[7][8] The second method is to mix fibres, cork and sand in an automated plant and to install it afterwards on the pitch.
[9][10][11] The third method is to put a carpet or mat with woven or tufted fibres on the surface, then to brush in sand or sand mixes to keep the fibres in an upright position and finally to seed grass mixtures on top.
