A refurbished industrial warehouse on Hull’s Alexander Dock required a new concrete floor slab to support the racking systems for timber handling. Nationwide Concrete Flooring designed and installed a 195mm deep steel fibre reinforced concrete floor slab using the company’s latest piece of kit – an SXP Somero Laser Screed.
This ride-on (which is so big it had to be taken to site by low-loader) comfortably coped with daily outputs of circa 350 square metres of concrete. The steel fibre reinforcement supplied by David Clark of Bekaert Limited was intergrated within the concrete by conveyor and the turning motion of the concrete trucks’ drums worked to create an even distribution of fibres.
One of the client’s requirements for the slab was the need for a straight grade fall from one end of the warehouse to the other. Co-ordinates were therefore inputted into the SXP’s computer control panel and the fall was automatically – and accurately – set.
Prior to the concrete floor being laid, the sub base leveler was used to control and compact the final trimming layer of stone. The steel columns were isolated using our typical column surround detail complete with isolation foam. Polythene wall protection was placed to minimize exposure to the cladding.

Nationwide Concrete Flooring Limited has completed the installation of another laser screeded concrete floor slab for a grain store in Bury St. Edmunds, Suffolk.
Perimeter shuttering was placed 600mm beyond the outside face of the steel columns. This detail allowed concrete to be placed underneath the pre-cast concrete wall panels to keep out vermin and rainwater. The outside strip of concrete was then finished using hand trowels whilst the inside was powerfloated with our large ride-on machinery.
The completed surface finish offers easy cleaning and maintenance whilst allowing grip for machinery.
Instant Seal 101 installed into the saw-cut induced contraction joints stops debris from falling into the cracks maximizing the risk of contamination into the stored grain. The Instant Seal also helps to protect the edges of the joints during heavy trafficking.

A new mushroom composting facility on the outskirts of Andover in Hampshire needed precisely leveled and powerfloated concrete floor slabs. After considering several companies to do the work they (understandably) chose Nationwide Concrete Flooring.
The internal concrete floor slab differed to most of our laser screed floors because a single fall from one side of the slab to the other was needed for drainage. The experienced Nationwide Concrete Flooring staff set up the laser screed concrete laying machine to take account of the fall during the concreting process.
The Nationwide Concrete Flooring powerfloating equipment was then boomed onto the concrete floor slabs using telescopic equipment. The finishers then provided a full powerfloated finish and sprayed the completed slab with a caring membrane.
The sawcut design was particularly interesting on this project as panels within the concrete were left at 10 metre centres due to the dimensions of the building. Rather than cut the joints at 5 metre centres, with the approval of the client Nationwide Concrete Flooring pushed the boundaries and cut joints at 10 metre centres. The completed saw cut joints were sealed with Nationwide Concrete Floor’s own Instant Seal 101.

Laying the supermarket concrete floor
A new supserstore in Leeds is the latest job well done for Nationwide Concrete Flooring, part of the Nationwide Diamond Group. The sales area of our largest supermarket concrete floor to date was completed in just two days using our laser screed concrete leveling machine while the main warehouse was powerfloated and took a further day. The warehouse was given a dry shake sprinkle topping and the sales area a course tamp finish.
Prior to the floor slabs being laid the sub base was trimmed using our laser guided sub base compact leveler.

The warehouse where the concrete floor was laid
A prestigious new warehouse at Markham Vale on a new industrial park off junction 29A of the M1 near Chesterfield required a high tolerance concrete floor slab.
Nationwide Concrete Flooring were contracted to install the powerfloated industrial concrete floor slab to the required surface tolerances. Due to the thermal values required for the building, insulation board was installed underneath the slab. This meant the readymix concrete had to be pumped as the insulation and steel fabric mesh reinforcement were all pre set prior to the casting of the concrete.
A dry shake surface hardener (sprinkle topping) supplied by Permaban was applied to the surface of the concrete floor slab to increase the abrasion resistance to category AR1. Due to the extreme weather temperatures a blended cement mix was used in the concrete to minimize risk of delamination between concrete surface and the shake sprinkle topping.
The client specified a flatness tolerance of FM2 special which other companies using direct discharge would have found difficult to achieve, but which Nationwide managed with ease by with a combination of its skilled workforce, pump laying and laser screed.
