Given the huge amount of concrete structures that surround us day to day, it is easy to take concrete for granted and how it enables us to live the lives we do in our evolving urban landscapes. Just like us, concrete needs to be maintained. It is affected by the stresses and strains of everyday life.Deterioration of concrete may happen due to corrosion, structural damage, water infiltration, seismic activity or a multitude of other reasons.

Years of research plus decades of practical experience have enabled Sika to develop a fully comprehensive solution to restore and rehabilitate concrete structures. Sika customer advice and support is second to none, from concept to successful completion on site. This is all based on more than 100 years of experience on large and small projects all over the world.

Key Causes of Concrete Failure and Why to Fix It

Deterioration of concrete is largely due to:
  • Chemical degradation, e.g. chemical exposure, alkali aggregate reactions, bacterial action
  • Corrosion of the reinforcement steel, e.g. carbonation, chlorides, stray electrical current
  • Mechanical attack, e.g. impact, overloading, movement, earthquake, explosion
  • Physical damage, e.g. freeze/thaw action, thermal movements, shrinkage, abrasion, wear
  • Underlying contributions, e.g. poor construction, design faults, lack of maintenance
Reasons for concrete repair:
  • Replace defective concrete
  • Restore structural integrity
  • Restore aesthetic appearance
  • Restore geometric appearance
  • Restore durability
