Concrete framed buildings, popular across various eras and especially in the mid-to-late 20th century, have provided us with enduring structures. From the use of Reinforced Autoclaved Aerated Concrete (RAAC) to different concrete types influenced by specific periods, the world of concrete buildings is diverse. However, like all construction methods, there can be potential issues. At Flettons, we’ve compiled a list of common problems you might encounter in concrete framed structures:

  1. Cracking: As a result of factors such as shrinkage, settlement, or deficient reinforcement, cracking is a prevalent concern.
  2. Spalling: Caused by moisture exposure or freeze-thaw cycles, spalling leads to the chipping or flaking of concrete surfaces.
  3. Corrosion: The reinforcement within concrete can corrode when exposed to moisture, salt, or aggressive chemicals. This weakens the overall structure.
  4. Delamination: Poor bonding or moisture exposure can cause the layers of concrete to separate, a phenomenon known as delamination.
  5. Honeycombing: Resulting from poor compaction, honeycombing refers to voids or air pockets present within the concrete.
  6. Uneven Surfaces: These may arise due to inadequate levelling, insufficient compaction, or subpar workmanship.
  7. Exposed Reinforcement: If the concrete doesn’t adequately cover the reinforcement, it becomes exposed, leading to potential corrosion and structural issues.
  8. Fire Resistance Concerns: Not all concrete structures are designed with optimal fire resistance, making them vulnerable in the event of a fire.
  9. Waterproofing Issues: A lack of proper waterproofing can result in water penetration, damaging the reinforcement and weakening the structure.
  10. Seismic Vulnerabilities: If not correctly designed for seismic resistance, concrete structures can suffer during earthquakes.
