I have seen epoxy-coated reinforcement used in concrete highway work in many areas. Is anyone using epoxy-coated reinforcement or ties in brick masonry construction? More
I have heard that a ladder-type bed-joint reinforcement should be used when connecting clay masonry to concrete masonry. Can truss-type bed-joint reinforcement be used when both the outer wythe and the inner wythe are the same material? If not, when can truss-type bed-joint reinforcement be used? More
Is it necessary to splice bed-joint reinforcement, or can consecutive sections simply be placed next to each other without splicing or overlapping? More
Our firm designed a reinforced grouted masonry barrier wall on a recent project. During construction, the contractor had several areas that blew out due to pressure from grouting. In some cases, wall sections completely collapsed. But in other cases, the wall just bulged outward between the lateral ties. How much of the wall should the contractor rebuild? More
Should drips be provided in the bed joint reinforcement in cavity walls to prevent water from being transmitted from one wythe to the other? More
The vertical reinforcing was left out of a 30-foot-tall warehouse wall. The problem was not noted until the roof joists and roof decking were installed on the building. Do you know any way to reinforce a wall after it has been completed? Or does the roof joist have to be shored and the entire wall rebuilt? More
