Hybrid grass or reinforced natural grass is a product created by combining natural grass with synthetic reinforcing fibres. It is used for stadium

pitches and training pitches, used for association football, rugby, American football, golf and baseball. Reinforced natural grass can also be used

for events and concerts. 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 sand and synthetic fibres as they grew. Three main methods exist to insert synthetic fibres in the root zone are as follows :

  • The first is to inject fibres in the sand with a tufting machine.
  • The second method is to mix fibres and sand in an automated plant and to install it afterwards on the pitch.
  • The third method is to put a mat with woven or tufted fibres on the surface, to brush in sand or sand mixes afterwards to keep the fibres in an upright position and to seed grass mixtures finally. The natural grass roots through the mat and stabilizes the system.
