Work almost finished!

Pouring of new panels on Runway 13/31 finished last week. The photo below shows one of the last panels being poured.




The photo on the left is of a panel that was removed and replaced, and the photo on the right is of a newly poured panel.

This week, subcontractors fixed more minor issues like mud balls and small cracks. To repair the mud balls, contractors remove the lip that covers the hole created by the mud ball, clean the hole, and fill it. 

The photo on the left shows a mud ball at the beginning of the project, and the photo on the right shows one that has been marked for repair and filled.

Today, workers were on site sealing joints and minor cracks. Joints are the spaces created between panels to prevent cracking caused by expansion of the cement. The workers also filled small chips on the edges and corners of some panels.


The photo on the right shows, an unsealed joint with chips, and the photo on the left shows a sealed joints and chips.





These photos show cracks before and after sealing.




This project should be wrapped up soon, allowing the runway to reopen.
