Deterioration of concrete may happen due to corrosion, structural damage, water infiltration, freeze and thaw cycles, seismic activity, reactive aggregates etc. Years of research plus decades of practical experience have enabled Sika to develop a fully comprehensive solution to restore and rehabilitate concrete structures.

Key causes of concrete failure

Deterioration of concrete is largely due to:

  • Chemical degradation
  • Corrosion of the reinforcement steel
  • Mechanical attack
  • Physical damage

Underlying contributors to deterioration:

  • Poor construction
  • Lack of maintenance
  • Design faults
