Many of these failures could have been avoided if the previous repairers had not tried to stick seaming tape to seaming tape without first keying the back of one one the tape runs to allow the adhesive to bond. It’s absolutely imperative that the repairers/contractors keep pressing the seams as they are curing if not they will lift and separate, where have I heard that before?
However,r we agreed to put things right and to this end we sent down three teams of men and machinery to completely cut out the failed joints including the old tape etc etc. and inserted brand new matching material and re-join it to the old pitch and make a safe playable surface again. The time taken? 180 man hours plus 130 sq m of new material and 100 kg of adhesives and hardeners.
Works completed and artificial grass re opened, happy days, but it could and should have been avoided, if it had only been done properly in the first place. The lesson? use a contractor with experience in installing and repairing these types of surfaces.
