Concrete floor replacement, Guildford, Surrey

 

The Nationwide Diamond Group has recently complete concrete floor replacement of an existing concrete floor slab and the supply and installation of a new steel fibre reinforced concrete floor at the Slyfield Road Industrial Estate on the outskirts of Guildford for a blue chip storage and warehousing organisation. Due to tight access restrictions and onerous working hours the Nationwide Diamond Group workforce were really up against it. Fortunately the wide range of plant and equipment available to the company’s workforce and under the guidance of our fully trained supervision the concrete floor replacement was completed over two separate visits with a full duration of 11 working days. The full scope of works consisted of saw cutting the perimeter of the existing concrete, drilling and dowelling the edge of the slab, re-grading, levelling and compacting the sub base working platform, supplying and installing steel fibre reinforced concrete with laser screed and power floated surface finish and finally all joints sealed with Instant Seal 101 and sprayed with Diamond Curehard dust inhibiting and surface hardening compound.
