Impala Platinum Holdings Limited (Implats) is in the business of mining, refining, and marketing of platinum group metals, as well as nickel, copper and cobalt. Imapala is also the second largest producer of platinum in the world.
The Impala Platinum slag granulation cooling tower in Rustenburg had several flaws that were causing cracks and severe water leakage. Because of the nature of this process, the reservoir could not be emptied for this repair process as not only would it stagnate their smelting process but it would incur enormous labour and operational costs. Therefore, repairs would have to be to the negative side.
Impala had numerous contractors come and do a test panel on the negative side of the structure to see if their solution would work for this extremely large 6m (20 ft) deep reservoir structure.
Kryton was the only successful product on these test panels, as such, Sanika Waterproofing were awarded the contract to repair and waterproof this structure 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 temp of over 80 C° (176 F°). After the Krystol Plug 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 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 where conducted by an independent consulting engineer appointed by Impala. The engineers determined that the Kryton solution is long term and of superior quality.
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.
The Krystol Leak Repair System is a permanent crystalline waterproofing solution used for repairing leaking cracks, holes and joints found in concrete. It reliably stops high water flow, even under high-hydrostatic pressure, and outperforms injection systems. Repairing leaks is a simple 3-step process that involves…
