Construction Testing & Analysis Inc. recommends that 4 inch diameter weep holes
spaced 8.0 feet on center be cored through the walls approximately 12 inches above the bottom
of the exposed walls to relieve hydrostatic pressures from behind the walls. Two helical piers
should be installed on the left wall, 3.0 feet each side of the noted crack, to prevent further
rotation of the wall. Five helical piers should be installed on the right entrance wall. One pier
should be located 3.0 feet left of the crack and step-up and one pier each should be located 3.0
feet, 10.0 feet and 16.0 feet right of the crack as well as one at the short column at the right end
of the radius.
After the piers have been installed and loaded for a minimum of 30 days, the brick can be
repaired. The weep holes should be installed prior to installation of the piers.
While we were on site, it was noted that two areas of the parking lot and curb adjacent to
the right entrance wall left of the radius have settled slightly. The areas should be maintained to
prevent water from ponding and possibly infiltrating the backfill of the walls.
We have enjoyed working with you on this project. If you have any questions or we can
be of further service, please feel free to contact this office.
