An array of anode assemblies for insertion at a plurality of locations in a gap between a section of a reinforced concrete structure and another solid structure is provided. Each anode assembly comprises an expandable member, an anode attached to the expandable member for protecting a steel reinforcement in the reinforced concrete structure, and an anode connector for interconnecting the array of anode assemblies. During use, each anode assembly of the array of anode assemblies is inserted into the gap, between the section of the reinforced concrete structure and the solid structure, at the plurality of locations. The expandable member of each anode assembly is configured to expand so as to press the anode into contact with a surface of the reinforced concrete structure.

Various embodiments of methods and apparatus for detecting a change in an orientation of a portion of a structure. In some embodiments, the apparatus includes a processor, an energy storage unit, a location reporting unit, a wireless communication module and one or more inclination sensors. In some embodiments, each of the one or more inclination sensors is configured to measure inclination by measuring an orientation of the each of the one or more inclination sensors relative to a gravitational acceleration vector.

Cathodic protection of steel in a concrete column in sea water is simplified by providing a pre-assembled unit including a jacket to surround the column carrying a bulk sacrificial anode outside the jacket and optionally an inner sacrificial anode with a cast grout inside the jacket. The jacket can also include a pre-assembled junction box and couplings to connect to the steel. The jacket is attached to the surface of the column at the water line so that the bulk anode is located below the surface of the water. The bulk anode can be formed of aluminum so as to be less toxic in sea water. An activator is applied inside the jacket either as a wicking layer or as a chemical activating material. The jacket can act only as a form work which is then removed after casting of the grout.

A device maintains proper downspout conductor pipe spacing and alignment. This stationary device attaches directly to the foundation of a home in any location utilizing different embodiments for straight walls, inside corners and outside corner conditions. The device provides fixtures or mounts to position the downspout accurately and reliably relative to the foundation and other components of the house or building. The device may be turned vertically in conjunction with a specifically formed soil and gravel guard to run downspout conductor pipes along the outside of a foundation before it is backfilled. By installing this system before backfilling, the installer is able to chalk line a path with consistent fall to ensure proper water flow through the pipe.
