KRYSTOLTM CONCRETE WATERPROOFING SYSTEM
Wellcome Supermarket
Hong Kong (S.A.R), China
BACKGROUND
Founded in 1945, Wellcome is the regions' longest - established supermarket chains and one of the largest in the region. Wellcome is owned by Jardine Matheson Holdings via its Dairy Farm subsidiary. Italso operates supermarkets in the Republic of China under the same name.
Failure of a conventional membrane system on the negative side walls at the basement level led to severe leakage problems throughout the area . Knowing that traditional repair products only work best after application but will soon deteriorate over time, the team seeked a different approach that would provide a long- term solution.
A trial test demonstrated the ability of Kryton's Crack Repair System to stop water in its tracks. SOLUTION
The full Crack Repair System was used to patch up numerous meters of cracks and damp spots on the walls. The team followed the application steps by starting with the Krystol Plug™ to immediately stop the f lowing water. This was followed by the application of the T1 dry pack and Ba r i - cote™. To f inish, Krystol T1® slurry was applied to cover all the walls and columns to prevent future leaks and damp spots from re-occurring a round the repaired crack areas.
After only 14 days , the basement resumed to its required dry state, enabling the client to finish the basement level , decorate, stock the shelves with products , and open for business ahead of schedule.
The basement walls remained dry even after heavy rainfalls - a measure of a successful repair.

KRYTON CRACK REPAIR SYSTEM
The Krystol system uses advance dintegral crystalline water proofing technology to transform porous concrete into a permanent , water - resistant barrier and provide a guaranteed defence against water damage and steel reinforcement corrosion . Millions of needle-like crystals begin to grow and spread throughout the concrete, self-sealing cracks and permanently blocking the movement of water in all directions . These crystals then remain dormant until another crack forms , at which time they will react with incoming water to sel f-seal the crack and maintaining a water tight seal.
Unlike other systems, Krystol® protects from any direction, even against high water pressure . Because Krystol can be applied to either side of the concrete , there are no limits when it comes to repairing or waterproofing hard or impossible to reach areas. Put Krystol to work wherever the cracks are—without
expensive, time consuming perimeter digging.
