If you feel your surface is under-sanded or doesn't have enough rubber infill it will certainly have a detrimental effect on both the playing characteristics of the surface and its longevity. In most cases the infill acts as a wearing course, so insufficient material will mean that more of the carpet fibres are exposed to players' footwear and wear rates will accelerate as a consequence. Clients should be careful when applying new infill to their surface that it is not only the right grade but also applied in the right manner. Simply 'dumping' the infill on the surface and spreading it will sandwich the fibres, causing more problems. Technical Surfaces has specialist machinery which allows a contolled application of infill to be spread and worked effectively into the carpet.
