02. Masonry injection grout
Cathedral Stone Products, Inc. offers a specially formulated injection grout that it said is proving valuable for reinforcing masonry in aging bridges and other large structures. Cathedral Stone’s Jahn M40 injection grout can be injected into cracks to stabilize masonry, including behind concrete or masonry piers, walls, arches, monuments, or building façades. Jahn M40 is a mineral-based grout that bonds naturally to masonry and is vapor-permeable so moisture or salt trapped inside masonry can escape. Vapor permeability greatly reduces the potential for deterioration caused by salt reactions in combination with freeze-thaw cycling, the company said.

07. Precast concrete bridge
Oldcastle Precast’s OMEGA bridge spans are 2 feet thick and designed to accommodate loads as great as 220,000 pounds.

For installation of a heavy-duty bridge for Carter Machinery, a Caterpillar Heavy Equipment Dealership in Mechanicsville, Va., 30 linear feet of 22-foot-span by 4.5-foot-rise OMEGA Bridge sections were offloaded from a truck and set into place in a single day. The bridge spans an existing, 4-foot-wide V-style ditch.
