Bridge Repairs at Conchas Dam

Conchas Dam Spillway Bridge at Conchas Dam, NM is in need of surface repairs. The existing deck/slabs have map cracking, degradation and delamination across its surface. Existing sealants at deck joints at all spans are compromised, and both vertical faces of these joints show primary efflorescence and rust colored staining. This proposed repair will preserve the bridge surface from deteriorating faster, preventing chloride infiltration into concrete, and causing an expensive repair of the full bridge deck. Repair damaged/delaminated concrete on bridge deck, and approach slabs and sidewalks (See Figures 1-4) Resurface/overlay bridge surface with an epoxy overlay system
