At CSC Services, we’re proud to have spent nearly two decades helping engineers across the UK’s water and power sectors keep their concrete structures safe and strong. 

Here’s a straightforward, step-by-step look at how we repair concrete, with real examples from our work. 

1. First, we scout the damage: Every repair zone is carefully identified, numbered and documented, especially on large sites. 
2. We check for weak spots: Using hammer testing, we find any hollow or corroded areas underneath the surface. 
3. We remove the bad stuff: We remove all damaged concrete back to a solid core. When we can, we expose the full steel reinforcement to at least 25mm behind the bars and 50mm past any visible corrosion. We also trim the edges of the area down to a clean 10mm border. 
4. We clear everything: All debris is cleaned out so we’re working from a clean, stable base. 
5. We prepare the surface: Grit blasting removes rust and contaminants, and helps re-profile the surface for the best adhesion. 
6. We protect the steel: Exposed reinforcement is treated with a specialist primer to guard against further corrosion. 
7. We rebuild: Repairs are reinstated using a bonding primer first, then the right repair mortar. Everything is done precisely to the manufacturer’s specifications. 
8. If needed, we go even further: For more complicated jobs, we might install a cathodic protection system (a corrosion protection set up) before filling the repair with mortar.
