Rocky Reach Dam Draft Tube Deck Repair

This project repairs the concrete on a section of the existing draft tube deck on the Rocky Reach Dam for Chelan County Public Utilities District.  A microsilica concrete overlay was poured over the draft tube deck.  Work involves installing wet containment measures on a section of the Rocky Reach Dam to prep for hydro blasting the Draft Tube Deck.  Hydroblasting and hand chipping will be performed on the deck to remove damaged concrete. A microsilica-modified concrete overlay will be placed on the deck.  Work also involves some new joint sealant, metalwork, and new paving.
