The Impala Platinum slag granulation cooling tower in Rustenburg had several flaws that were causing cracks and severe water leakage. The repair process would not only stagnate their smelting process; it would also incur enormous labor and operational costs. To see if their solution would work, Impala had numerous contractors conduct a test panel on the negative side of the 6 m (20ft) structure. Since Kryton was the only product successful in the test panel, Sanika Waterproofing Specialists, the Authorized Distributor in South Africa were awarded the contract to repair it using Kryton’s Crack Repair System.
Sanika had to remove the unsuccessful membranes and other products from the structure to prepare it for the crack repair and waterproofing process. After preparing the surface, Sanika had to act quickly with Krystol Plug as the water penetrating through the cracks was at a temperature of over 80 C° (176 F°). After Krystol Plug had successfully stopped the flow of water, Sanika employed the rest of the Krystol Crack Repair System followed by a coat of Krystol T1 & T2 to completely waterproof the reservoir.
Impala was extremely pleased with the work and had this to say, “Sanika performed the work in an exemplary fashion, with due respect to all safety, environmental and quality aspects. The work was executed within budget and on time with a very high standard of quality.”
Subsequent inspections were conducted by independent consulting engineers appointed by Impala who determined that the Kryton backed products would provide superior quality in the long term.
As part of the Krystol Leak Repair System, Krystol Repair Grout is a crystalline concrete waterproofing product that stops the flow of water to permanently repair leaking cracks, holes and joints in concrete, and can also be used to resurface and waterproof defective, damaged or deteriorating concrete. The grout employs advanced fiber technology and shrinkage controlling additives to prevent cracking.
