When the management of the Victoria and Alfred (V&A) Waterfront in Cape Town identified the need to repair their leaking glass skylights, a Sika South Africa product saved the day. Sikasil Bridge Tape-300, a preformed silicone-profile tape, was used for the first time in this type of project in South Africa to help repair the 4 600m tall project.
Chris Sharpe, Sales Representative at Sika South Africa, says the revamp of the skylights began in July 2019. It was decided that the method of over-sealing the glazing joints would be used. She says that the Sikasil Bridge Tape-300 system, was placed over the original sealant to seal all existing joints, fully waterproofing the skylights.
Sikasil Bridge Tape-300 system was used because it is an ultra-low modulus silicone tape that is an economical alternative to cutting out the existing failed joints in the skylights. Some advantages of this tape include high tear resistance, resistance to corrosion and ultraviolet (UV) resistance.
According to Sharpe, Sika South Africa also initiated training to ensure that the job was done in the correct way. Other products by the company used in this unique project included Sika Aktivator 205, an adhesion promoter, SikaHyflex-305AP as the adhesive for the silicone tape and Sika Clean-Glass, which left all glass surfaces meticulously clean.
“The V&A Waterfront is one of the most visited tourist destinations in Africa, known for beautiful architecture, heritage sites and attractions, so it is imperative that this gem is maintained year around. Sika South Africa is proud to have been part of such a prestigious project; and is glad that the waterfront could benefit from their products and methods,” says Sharpe.
