Too much sand or rubber on your surface will not only be unsightly but will also represent a hazard to your users. It is important that infill levels are kept in line with your installer's recommendations, normally to within 1mm of the surface for sand-filled pitches and 3mm for rubber-filled surfaces. It is normal to find excess infill around the perimeter or corners of the surface. This occurs through general play with the infill being dispersed away from the central areas. Regular Drag brushing can help eradicate this. Excess infill also occurs when the general wearing of the carpet pile (normally 1mm per year) exceeds the natural migratory loss of the infill. In this case it will be necessary to remove an amount of infill from the playing surface to ensure the correct tolerances are achieved and the playing characteristics of the pitch are maintained. Achieving this can be very difficult as 1mm of surface infill over a full-size pitch can equate to nearly 6 tonnes!
