High wear areas of artificial sports pitches often require attention, areas around goals, penalty spots etc. can become badly affected and need repair.
Adhesives can break down and seams and lines may need to be replaced. Rain and frost on older sports surfaces can penetrate under the artificial carpet; this action can cause adhesives to break down and seams to fail. Worn areas can be cut out and patched; sub-surfaces may also require attention, especially those which may be found to be around collapsed drains.
