Renovating industrial flooring which is either damaged or has deteriorated over time can be a total headache. Just the thought of ripping up a concrete floor just to replace it with new sounds expensive. But, there are other options such as renovating the floor using a heavy-duty cementitious screed.

What is a heavy-duty cementitious screed?

Heavy-duty Cementitious screed systems are a flow applied rapid hardening system made up of Polymer.

Fast to Apply and Fast Drying

Heavy-duty Cementitious screed is not only fast to apply, but also self-smoothing. Therefore, it provides a fast-track solution to ensure flooring is fit-for-use as soon as possible.

This fast-drying system has the ability to allow foot traffic onto the project within a few hours. In addition, the floor would be ready to receive vehicle traffic within 24 hours.

Quick And Economical

Cementitious Pump Screeds have many advantages, but most importantly they are quick and economical. Firstly, you do not have to dig up the existing concrete floor, causing minimum disruption. Using heavy-duty pumping solutions allows vital work to be undertaken and completed in the shortest time possible. Therefore, minimising loss of productivity time and disruption.

In harsh environments, such as warehousing or engineering plants, timely work can be extremely inconvenient and disruptive to staff and machinery. This is when a cementitious screed is ideal to use.

1230 SQM Warehouse Floor Refurbishment

PSC Flooring recently worked with a company called NAL Ltd to renovate their industrial warehouse floor. They are a specialist manufacturer and supplier of a wide range of infrastructure products based in Worcester.

The floor are itself was 1230 square meters. It was a concrete floor that was old and worn with areas of heavy pitting, ridges, and general wear.

At the site visit many options were discussed. It was decided that to renovate this industrial flooring, it would need a heavy-duty cementitious screed. This would strengthen the existing concrete and provide a new smooth floor surface.

In Preparation

In order to lay the screed, the entire floor was given a heavy shot blast via the totally enclosed ride on shot blasting machine. The edges were diamond ground back using the handheld 110v diamond grinder.

The floor was then vacuumed clean. After that, two coats of DCP Strong coat DPM epoxy resin damp proof membrane priming system were laid to total floor area. Additionally, it incorporated a heavy scatter of 0.6 to 1.2mm quartz aggregate.

The final stage of the floor preparation was to make repairs to localised damaged concrete, holes, cracks and expansion joints, as required using polyurethane mortar compound.

Laying 8mm Pump Screed and High Build Epoxy Resin Flooring System

A nominal 8mm DCP Cemflow cementitious screed was machine pumped to total floor area. Once dry the existing expansion joints were mirrored through by saw cutting 10mm x 8mm expansion joints, knock out and infilling with jointing compound to circa 307 linear metres.

The surface was then lightly abraded using the doubled headed diamond grinding machine to prepare for the High Build Epoxy Resin Flooring System. Two coats of Resdev Pumatect high build epoxy resin flooring system, were applied to the 1230 square meter warehouse floor in the clients chosen mid grey colour.

Finally, the walkway was then masked out and two coats of Resdev Pumatect high build epoxy resin flooring system, in green with a yellow outline was applied to the pedestrian walkway area, circa 50 sq mtrs. In all this job took 11 working days, completed on time and within budget.

Mr Ade Kenney, QHSE Officer of NAL Ltd commented:

“PSC have completely transformed the warehouse floor. We couldn’t be happier with the finished product.”

The floor is now ready to take on the heavy bourdon of warehouse life, with the racking being installed just 48 hours later.
