We would suggest the following timescales:
1. No access is permitted onto the slab for any person other than the finishing crew until the curing membrane is thoroughly dry; this is normally 24 hours
4. At 7 days old the slab can be trafficked by light vehicles and scissor lifts
5. Heavy Goods Vehicles shall not be allowed on the slab for a period of 28 days
6. A designated single access point for HGV’s shall be identified. An unloading area adjacent to this, shall be protected with a breathable floor protection product and covered with 20mm thick plywood or chipboard
7. Lay down areas should be located in the centre of panels (minimum 5m from construction joints) and protected with polythene and covered with 4mm hardboard sheeting
8. Ensure that the fit out is coordinated with the casting dates (i.e. erect racking on the oldest panels first)
11. Avoid bolting of racking that spans construction joints until the slab is 90 days old
12. The racking should remain un-loaded for as long a period as possible
13. All plant using the slab to be fitted with non-marking tyres or wheel covers and oil drip catchers and should be checked and maintained in good condition
14. Floor cleaning is to be carried out strictly in accordance with the recommendations to be provided by the sub-contractor or advisor
15. Maintain temporary weather protection at doors in place for a minimum of 7days after casting of slab, unless being replaced by permanent works. Keep all dock-leveller, pedestrian access and other doors closed, except when in use
