I've offered to help my neighbour tidy up her driveway. I've ordered a new drain cover but many years ago Thames Water did a drain repair and concreted near and around the inspection chamber. This is now in poor condition as vehicles drive over it regularly. She is saving up to have the whole drive renewed but just wants a quick cosmetic fix to last a year or two. Any recommendations for a mix that will do the job? It's a small area so something ready-mixed would be good. I know I'll need to cut out any loose stuff first.
