Car Park Marking Ltd. had to carry out refresh work on the London underground network of car parks leading up to the London 2012 Olympic games. This work had to be done with precision, giving cars enough room to park in an orderly way. Car park markings in white and yellow thermoplastic screed were applied. At Colindale station, London, we had to remark the Keep Clear markings so that access could always be gained to the station. This was of particular importance in the run up to the London 2012 Olympics.
