How to Repair and Protect Concrete

Most of us will be aware of so-called ‘concrete cancer’ and other forms of damage to concrete. The most common causes of concrete damage are:

  • Carbonation caused by CO2
  • De-icing salts
  • Insufficient steel cover
  • Poor concrete quality

The Vandex Concrete Repair System provides a systematic procedure for concrete repair. The system consists primarily of cementitious materials which are homogeneous with concrete (strength, modulus of elasticity, thermal movement).

1 Carefully remove unsound concrete and expose reinforcing steel completely.
2 Remove rust and clean the reinforcement steel by sandblasting or other suitable mechanical methods.
3 If available, use highest water-pressure technology and remove unsound concrete completely. Remove rust and clean.
4 Stop further corrosion by applying Vandex Uni Mortar 1 Z that has been mixed using Vandex Anti-Sulphate Agent.
5 Rebuild concrete using Vandex Cemline MG4 repair mortar. For horizontal surfaces, Vandex Cemrep 202 can be used.
6 Apply surface protection using Vandex Cemelast.

A variation of this system, incorporating Drybase Universal Mortar as a repair mortar, can be used when repairing concrete in swimming pools. Please contact our technical department on 01403 210204 or submit an enquiry for further details.
