NottsBase'D' System NG12 The unique NottsBase D System NG12 offers a more consistent performance than aggregate-based pitches. It also provides a narrower range of playing characteristics in relation to bounce and pace, making it an ideal pitch for encouraging player confidence during coaching or matches. Because the NottsBase D system NG12 uses synthetic rather than natural performance control layers below the surface, less maintenance is needed during the life of the pitch. If your ground requirements change in future, the NottsBase D pitch can also be relocated at minimal cost.
