HBA repairs

During part of the site inspection we found a very small hole in one of the HBA tiles. We suspect that this may have occurred during the recent fitting of the summators. Because of the hole, there had been water seeping into the tile. A temporary fix was implemented and we drained the water out.

Normally HBA tiles should self drain. There are holes in the tile base for that purpose. However, because of the framesets at KAIRA, our support locations are different to where they normally would be, which is why water was pooling in the tile base.
