Make OR Break Factor
The congestion of steel in the reinforcements hampered our initial progress as well as overall process, but satisfactory results were managed.
THE CHALLENGE :
- Cavities in the core concrete of the foundation of the wind turbine were making the whole structure unstable.
THE ODDS :
- The existing concrete foundation housed steel reinforcements that were very closely placed, making it virtually impossible to drill holes to fix nozzles.
OUR RESPONSE :
- After an initial assessment, we excavated a bit to reveal the concrete foundation, in which we proceeded to drill holes for fixing ports to help us grout the cavities, which we did with modified cement grout.
