Mapei South Africa’s waterproofing products were used to repair leaking fire tanks at the Tubatse Crossing Mall in Burgersfort in Limpopo.
Waterproofing product supplier, Mapei South Africa, offers the South African construction industry a range of international products that has helped both professional contractors and DIY builders to overcome various waterproofing challenges.
The Tubatse Crossing Mall in Burgersfort in Limpopo, which opened in 2013, recently faced a problem of leaking fire water tanks. The tanks had originally been lined with DPM plastic bladders, which had failed because of abrasion from sharp protrusions in the tanks. Pretoria-based Steed Bekker Waterproofing (SBW) was able to rapidly and effectively waterproof the tanks using Mapei products.
The contractors, which are approved Mapei South Africa applicators, needed to strip out the bladders of the fire tanks in order to refurbish and reline the tanks. SBW’s owner, Steed Bekker, says the company has been using Mapei’s waterproofing products for 18 months and find the products to be effective.
“All the Mapei products have been easy to apply and produced successful projects – their ease of use is a big benefit on fast-track projects,” commented Bekker.
Products used to refurbish and reline the tanks
The SBW team used Mapegrout T60 in order to repair the concrete tanks, followed by reinstatement of the concrete fillets with Mapecem Pronto and Eporip Wet to Dry, a two-component epoxy adhesive for repairing cracked screeds.
“The challenge with waterproofing the tanks was dealing with negative pressure from leaking adjacent fire tanks that had to be kept full of water. The solution we found to be effective was Mapelastic Foundation, a two-component cementitious product that forms an elastic membrane designed to withstand positive and negative pressure. This was applied at a rate of 3,2kg/m² and reinforced with Mapenet 150, an alkali-resistant glass fibre mesh,” explained Bekker.
The refurbishment project was awarded to SBW in October 2013 and was completed a month later with 100% successful waterproofing of the tanks.
“Without question, the Mapei products support the claims of being the outcome of tried and tested international research and development. We were also very appreciative and impressed by the backup from the Mapei South Africa team. They are always willing to help, have good technical knowledge and give my teams good practical advice and demonstrations,” said Bekker.
SBW is currently using Mapei waterproofing products to seal the roofs of The Grove Shopping Centre, a prestigious development in Pretoria East. The contract involves thousands of square metres of Polyglass Evolight, combined with the latest Mapei product coatings. Mapei South Africa’s recently introduced Aquaflex Roof is being used on the difficult interfaces between parapet walls and metal roofs.
Mapei South Africa’s advanced building technology additives, sealants, adhesives and concrete performance chemicals have become well-known in the local construction industry over the past six years. Offering outstanding performance and handling advantages, Mapei’s 1 400 products are recognised throughout Europe, America and the Far East.
