Los Angeles is a seaside town with a balmy, Mediterranean-like climate, and a very active seismic scene. This combination of local conditions makes for a tough environment in which to create and maintain concrete structures in the city.

Older concrete structures are particularly vulnerable, as heat, water, and earthquakes have already taken a toll on them. With numerous contractors throughout Los Angeles specializing in concrete waterproofing and remediation, the following nine are the masters of this space- and life-saving craft.
