The damage I assume is in the areas where the wagons and forklift operate
Did a recover some years ago 6in deep in concrete,closed yard on Wednesday night before a Bank Holiday employed a joiner to erect formwork around perimeter to be covered used old scaff boards,bought in steel reinforcement sheets and lifted drains set out rain run off slopes. We excluded areas where the cabins,tube racks and pallettes were stored All the formwork ect was completed on Thursday,we concreted on the Friday Morning and was in the Pub for 1pm That gave it 3.5 days to cure and apart from a little scuffing with the forklift it was good and solid.We used a concrete pump to spread the concrete and a couple of small vibrators (borrowed off the wife and sister in law)
We used all our own labour apart from the joiner and had a good laugh during the job,Yard was up and running as normal on the Tuesday after the holiday.I cannot remember the costings but I think it was around £15,000 for the lot
At a later date we moved the palletts and cabins and did these areas
