Concrete Repair

Concrete in its simplest form, as explained by Portland Cement Association is “a mixture of paste and aggregates, or rocks” that through a chemical reaction called hydration, hardens and gains strength to form the rock-like mass known as concrete.

Concrete is one of the most used and durable man-made materials in the world. And, it is an important construction material used extensively in buildings, bridges, roads and dams, where Its uses range from structural applications to paviours, kerbs, pipes and drains. 

Pro Crew Schedule states that “concrete in the present infrastructure has been deteriorating at a fast pace due to the corrosion of reinforcing steel coming from the including chloride and other ions from road salts, marine areas and ground soils, making concrete a “complex composite, which needs improvement, monitoring, and control.”

Reasons why concrete may damage: 

  1. Alkali Aggregate reaction in concrete
  2. Corrosion of embedded steel
  3. Fire or Heat
  4. Abrasion/Erosion
  5. Chemical Attack
  6. Overload and Impact on concrete
  7. Surface defects

What these damages may result in: 

  1. Cracks
  2. Spalling
  3. Settlement
  4. Lifting

What is concrete repair?

Concrete repair is the process of fixing a hardened concrete surface that over time has lost the ability to hold the binding concrete materials together due to damage or environmental exposure. 

Concrete repair is appropriate for cracks, physical impacts, chipped out surfaces or surface scaling, as explained by Concrete Renovations UK.

It is important to keep in check the quality and state of concrete to ensure that there is no wear and tear, and if there is, that it is tended to immediately, as “if left unchecked or unrepaired, it can further disintegrate the concrete structure.”

For small scale concrete repair, such as fixing a concrete path you can:

  1. Remove the damaged concrete from the path
  2. Make a straight edge for the concrete path with formwork
  3. Make a curved edge for the concrete path with formwork
  4. Pour concrete into the formwork mould and level it off.

Alternatively, for general concrete repair, these instructions provide a basic guide

  1. Using a Chisel, Make the Crack Wider at the Bottom than the Top
  2. Clean Out the Debris with a Stiff Fiber or Wire Brush
  3. Fill the Crack with Patching Mix (also known as Vinyl Concrete)
  4. Address Any Pop-Outs
  5. Wet the Surface and Apply a Concrete Bonding Agent
  6. Pack a Small Amount of Anchoring Cement into the Hole

However, fixing damaged concrete is not necessarily an easy job to do, and often, hiring professionals may be the best option.
