JOINT REINFORCEMENT FOR CONCRETE MASONRY

Cross wires 16 in. (406 mm) on center should be used for reinforced concrete masonry construction, to keep cross wires out of the core spaces, thus preventing them from interfering with the placement of vertical reinforcement and grout. Truss-type joint reinforcement (Figure 2) consists of longitudinal wires connected with diagonal cross wires.

Vertical Impermeable Barriers (Cutoff Walls) | Geoengineer

The grout is injected through another jet so that a column comprised of almost pure grout is formed as the drill rod is lifted. These columns can have diameters as large is 3 m in granular soils and 1.5 m in cohesive soils. A triple rod jet grouting setup injecting grout, water and air into the soil is depicted in Figure 8 (USEPA, 1998).
