Concrete Repair
Indeed in order to specify the proper repair solution we must know if we are in front of mechanical, chemical, physical damage or even carbonation damage. Proper assessment survey and diagnosis of damage must be extended before concrete repairing.
Basically, in this field Sika is proposing either additive promoter for mortar, like the well know Sika Latex, or ready to use pre-dosed mortar. Mortar could be cementitious or epoxy based.
For instance for mechanical damage the Sika MonoTop range – one component polymer modified cementitious mortar offers all variety of products covering from bonding agent to thick repair mortar.
- Chemical damage (like Alkali aggregate reaction) could be fixed with the Sikadur epoxy range mortar.
- Structural repair (crack) will be injected with Sikadur 752 – 2 component epoxy resin low viscosity.
- SikaGrout range – cementitious pumpable grout could be used for surface repair (honeycomb) for instance.
