Nationwide Concrete Flooring contractors recently completed another concrete floor repairs job in Rotherham, South Yorkshire.
The client requiring the concrete floor repairs trades in the worldwide field of specialists engineering, and needed their existing, deteriorating floor slab replacing as it could no longer support the weight of new equipment being delivered from Japan – Japanese engineers had stipulated the machinery had to stand on a slab no less than 1 metre deep.
Gabbitas Gill Partnership engineers from Hull had worked with Nationwide Concrete Flooring on numerous other projects and so therefore had the confidence in their ability to be able to carry out the full removal and replacement comprising the concrete floor repairs.
Main contractor Ashfield from Leeds originally wanted a concrete flooring contractor to supply and lay the Sika Syntop Red dry shake topping and surface harder. Once it became apparent that Nationwide Concrete Flooring had the expertise in both the applying and installing of dry shake surface hardener and the removal of concrete floor slabs, Ashfield contracted Nationwide to carry out the full package.
The existing concrete floor slab had to be removed throughout the night in order to minimise noise, vibration and mess. Once the concrete had been saw cut into small sections using the full depth hydrostatic diamond blade floor saw, the Nationwide Concrete Flooring concrete crushing attachment then crushed the sections of concrete into recyclable hardcore.
The high strength concrete was then pumped into the working area and laid using laser levelling technology to a flatness tolerance of Fm2 to the 3Rd edition of TR34. The Sika Syntop dry shake surface hardener was then applied to the surface of the concrete during the powerfloating process and then cured using Nationwide Diamond Curehard, which seals the floor and minimises dusting from the concrete surface, thus completing the required concrete floor repairs.
During the concrete floor repairs Nationwide Concrete Flooring contractors used a full depth hydrostatic floor saw, concrete breakers, laser screed, powerfloats, dry shake topping spreaders and mini dumper.
The breaking out of the concrete was carried out over a 4 night period with re bar fixing (see photograph) and concrete taking a total of 3 days. This was 6 days ahead of programme.
