The Head Quarters of First National Bank recently benefited from an extensive refurbishment project which entailed the resurfacing of 28,000m 2 of flooring.
This R236 million project was enhanced by the use of TAL Screedmaster Industrial for the installation of flooring undertaken by Top Carpets and Floors Pretoria.
The FNB Head Office Building is located at 1099 Corner Pritchard and Harrison Streets in Johannesburg’s CBD and the entire 22-storey, four-basement office building underwent redevelopment and refurbishment.
Surface preparation necessitated lifting of all old carpeting and removal of the residual carpet glue by means of a concrete floor grinder. Because this process left the existing substrate too uneven to receive new carpet tiles, TAL Screedmaster Industrial, was specified for smoothing and levelling the surfaces. Levelling of uneven substrates prior to the installation of new floor coverings is an integral part of the underlayment process that must be managed professionally using the correct floor-levelling compound, tools and expertise.
Manufactured from shrinkage-compensated cement and selected aggregates, TAL Screedmaster Industrial is a single component, high performance heavy-duty, self- levelling and smoothing underlayment compound. As with all TAL levelling compounds, TAL Screedmaster Industrial is VOC compliant. When added to water, its high flow properties require minimum installation time and produce a smooth, flexible and durable floor surface prior to the fixing of floor coverings. TAL Screedmaster Industrial is trafficable after three hours and sufficiently cured to receive floor coverings after only 24 hours.
Screed buckets, each filled with the specified mixing ratio of 2 x 22 kg bags of Screedmaster Industrial and ten litres of water, proved physically challenging for applicators working throughout the multi-storey building. TAL solved this challenge by providing two-wheel trolleys for easier mixing, transportation and pouring of the product at the points of application. It was estimated that the trolleys reduced the screed application times by approximately 40%.
Further challenges included site accessibility for large deliveries and lack of storage space for the quantity of product required. By using a crane truck to deliver no more than three to four days’ worth of TAL Screedmaster Industrial, off-loading was accelerated and lack of storage space was eased.
Thanks to the partnering of TAL and Top Carpets and Floors Pretoria, the results of this extensive project proved highly successful.
