Construction solution
Concrete Repair & Protection
Repair damaged concrete and protect structures against further deterioration.
Solution overview
Understanding the application.
Nia Build provides concrete repair and protection solutions for damaged, cracked, spalled and deteriorated concrete. The repair approach is based on the condition and cause of deterioration rather than simply covering visible damage, allowing the appropriate repair and protection materials to be specified.
Common signs
What may be happening.
Cracks, spalling concrete, exposed reinforcement, rust staining, delamination, broken edges, surface deterioration and previous repairs beginning to fail.
Assessment & considerations
Understand the conditions first.
Determine the extent and likely cause of deterioration, concrete condition, reinforcement corrosion, crack characteristics, environmental exposure, structural significance and condition of previous repairs.
Solution approach
Select an appropriate system.
Remove unsound concrete where required, clean and protect exposed reinforcement, prepare the substrate, reinstate damaged sections with suitable repair materials and apply additional surface protection where the exposure conditions require it.
