Introduction:

Nationwide Concreting were asked to undertake a concrete floor installation for Marbank Construction in Southall. We supplied all labour (18 operatives) and plant to install concrete floor slabs measuring approximately 4656m2 over the mezzanine and the ground floor.

Production Process:

We started the process by placing the Visqueen membrane, mesh and bar reinforcement. We fixed a 12mm miothene compressible foam isolation joint to the perimeter of the building and then fixed 20mm miothene to all columns. We followed by placing opened rolls of 1200 gauge membrane across the width of the pour, ensuring a minimum lap of 400mm. We finished by placing a layer of A142 and a layer of A193 of mesh fabric reinforcement and by making sure that the slab is clear of any trip hazards before the pouring procedures started. 

Our Concrete Pump Operator started the mezzanine pouring procedure by mixing 2 bags of Portland cement with clean water to form the grout needed to prime the pump. The concrete was then vibrated using a petrol driven poker unit, while the other operatives levelled the concrete using our specially adapted concrete rakes. The levelled concrete was checked using the levelling staff giving our Nationwide operative the go to "strike off and compact" the concrete using a petrol driven vibrating concrete screed. 

The Concrete Technician created the correct slump for the ground floor slab and once that was established, the concrete was discharged onto the Visqueen. The operatives checked the levelled concrete carrying out checks at 500mm centres using the levelling staff. The laser screed was used after this to make the appropriate adjustments. 

After the concrete was hardened sufficiently to support the weight of men and machinery, our operatives started the power floating process leaving a smooth level, finish, free from all noticeable ridges was achieved. The finished surface was sealed and cured immediately after the finishing process was completed, making it possible to walk on the surface without marking.
