This SAB Miller heritage building in Braamfontein, South Africa had many defects in the existing plaster and concrete basement area and required repair. Because this was a heritage site, any waterproofing and repair would have to be conducted without damaging existing plantation and vegetation on site. Essentially, this meant that only waterproofing systems that could be applied from the negative side of water pressure could be used.
Kryton’s crystalline waterproofing technology is unique in its ability to repair a damaged structure from the negative side of water pressure. The system is also cost-effective, and ensures the longevity of the concrete structure.
The Krystol Leak Repair was employed to successfully repair and waterproof the reservoir: first, Krystol Plug™, a rapid-setting hydraulic cement product, was used to stop water penetration, following which Krystol Repair Grout™, which is used to resurface defective or deteriorating concrete, was used to stop the concrete from cracking. Lastly, Krystol T1® was used on the surface to transform concrete into a waterproof barrier.
SAB Miller was extremely satisfied with Sanika’s commitment to the project and with the final result: a dry, impermeable (to water) concrete surface which helped restore the heritage site to its original splendor.
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.
