- For rapid and permanent reinstatement of localised thick section patches in concrete carriageways, pavements, airport aprons, access ramps and floors.
- Fosroc Patchroc 250 has a unique cement chemistry to rapidly reinstate very large bay sizes without excessive heat generation and associated cracking
- Particularly useful when interruption of traffic must be minimised
- The product is alkaline in nature and will protect embedded steel reinforcement. It may be used internally and externally.

- One component, pre-bagged to overcome site batched variations requires only the site addition of clean water
- Does not normally require a primer to achieve high bond strengths
- Excellent bond to the concrete substrate
- Shrinkage compensation ensures no cracking
- Controlled heat of hydration minimizes risk of thermal cracking.
