Sika Unilever ice cream factory Jnl 4 16

Several Sika products were specified for a new ice cream factory boasting the latest green technology.

As a reliable supplier of high performance flooring systems, Sika was recently awarded the flooring contract for Unilever’s new state-of-the-art ice cream factory at Lord’s View Industrial Park in Midrand, Gauteng. The first factory of its kind in Africa, it boasts the latest green technology including zero waste to landfill and the use of smart water efficiency technology.

Engineers from Pharmadule, together with advice from Sika representative Chad Tosen, specified six Sika products for sealing, screeding and coating of the factory floor. All Sika products specified are approved for use in food processing plants, and boast multi-international endorsements. Industrial flooring specialist, Seal Con Systems, was contracted for the 2 600m2 project which included extensive grinding of the floors prior to application of the Sika products.

Cracks and voids in the floor were filled with Sikadur-52 ZA, a two-part, low viscosity injection liquid, based on high strength epoxy resins. Solvent-free and suitable for both dry and damp conditions, Sikadur-52 ZA provides good adhesion to concrete, mortar, stone, steel and wood. It provides shrinkage-free hardening and not only forms an effective barrier against water infiltration and corrosion-promoting media, but also structurally bonds concrete sections together. Since low temperatures do not affect its performance, Sikadur-52 ZA was ideal for this project, which took place during winter.

Floors were primed with Sikafloor-161, a two-part, solvent-free, low viscosity epoxy resin that is economical and easy to apply. Suitable for normal to strong absorbent surfaces, it provides excellent bond strength and short waiting times. The primer was overlaid with a 6mm coating of Sikafloor-21 N PurCem, (1 100m2 beige, 1 500m2 dark grey), a three-part, water-dispersed, medium to high strength, polyurethane modified cement and aggregate screed with self-smoothing properties.

Its excellent flow characteristics allowed for easy application while its aesthetically pleasing smooth textured aggregate surface is easy to clean and provides medium slip resistance.
