As experts know, traditional concrete waterproofing performance decreases over time. This was the case at the Magyar Suzuki car manufacturing plant in Esztergom, Hungary, where a 25-year-old below-grade tunnel began to leak. Water was discovered at a pipe penetration and a joint between the concrete block wall and the slab roof. Repairing the leaks quickly was essential because the tunnel houses expensive and specialized pumps that are used to transport sensitive liquids, such as gasoline, from transport tankers to the factory tank park.
The leaks were repaired using Kryton’s Krystol Leak Repair System. Krystol Repair Grout was applied on the negative side of the wall at the pipe penetrations and joints. A layer of Krystol T1 was then applied to the block wall surface to provide a final barrier to water. The Krystol technology in the repair system chemically reacts with water and un-hydrated cement particles to form insoluble needle-shaped crystals that fill capillary pores and micro-cracks in the concrete and block the pathways for water. Any water coming into contact the concrete in the future will initiate crystallization, ensuring permanent waterproofing protection.
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.
