We are about to pour a concrete bond beam over a brick wall. It is old
brick. Other than blowing it off real well what surface prep should we
do before pouring on top of this brick? There is nothing specified.I am
thinking of some sort of chemical or treatment to improve the bond.
Have you considered the precast "U" shaped concrete beams that are the
type that are used as bond beams or lintels over doors and windows?
Use portland cement mortar beneath to level the precast units, water
soak the brick and precast first, and use threaded anchor rods into the
drilled and possibly pointed brick wall [and that extend up through the
wood structure? above]. Add rebars lengthwise in the channel, and fill
even with concrete.
Is the wall a garden type wall? If so, you may want to consider a
precast concrete capstone that is pinned and mortared to the brick. The
same for a parapet wall. Use a formed wire ladder beneath the units, for
example, by, http://www.dur-o-wal.com /.
Ask the right person: email@example.com .
It may be presumed that since bond beams in walls are nearly always
placed in building walls, however, that isn't necessarily always so.
tonyg hasn't replied to previous questions. He could get the appropriate
answers, here, and he is silent.
I'm beginning to to think that when I provide answers to questions on
Usenet that I will also send a CC reply to the sender to wake them up.
Perhaps the wakeup CC would be a good idea prior to the next text reply.
These days there are so many posters that don't even say thank you.
