During the original construction of the Supergroup warehouses in Isando, the roof had been subjected to incorrect installation methods by previous contractors and poor quality control. The roof remedial project we undertook encompassed reviews of the structure and roofing elements which amounted to a 6 million rand contract. The majority of works included extensive steel modifications and almost all the flashings to the roof were replaced to meet professional specifications, as they were originally under-sized.
A hot dipped galvanising plant, of which the acidity of the atmosphere was between 17-30%. Roof structure and sheeting had corroded to a point where the building was soon to be condemned. We provided a solution whereby new roof purlins installed were corrosion protected in terms of a polyurethane coating and stainless steel bolts to connect to structure. An Advanced reinforced fibre glass anti-corrosion sheet was installed which allowed for walk-on capabilities. Its translucent properties also allow for the benefits of natural lighting.
Worldwear shopping centre, just off Beyers Naude, required extensive gutter maintenance in order to maximise the longevity of its water management system. The system that we installed over roughly 2km of gutters, with the correct maintenance, will provide exactly that. The roofs' general condition was also assessed and addressed to ensure the client received the most professional service.
The Tupperware manufacturing plant in Springs suffered from poorly corroded gutters. There were areas where the gutters could be refurbished and maintained, but in others a whole new gutter had to be installed to rectify the buildings leaks. Wider gutters were installed to cope with the large amounts of water we have been experiencing in recent storms.
