    Default No mortar in perpend - how do they do this?

    Hi all,

    I've been looking at an amazing building that has no mortar in the perpend and would like to do something similar as they give the impression that the bricks are longer than they actually are (230 x 110 x 50mm)

    In this example, bricks are 50mm high and seem to be sitting on a 10mm bed joint but are butted up against each other with no perpend mortar joint.

    Any idea how this is achieved to meet AS3700 code? I'm assuming that the inside face must either be lined or painted with an impermeable waterproof membrane to stop the water seeping through when it rains?

    Anyone come across this before?

    Thanks,

    alps.

    Maybe a bead of caulk of some description? Sounds interesting. Did you get a photo?

    it is achieved with certification as an alternative solution, because the deemed to comply solution of the masonry standard requires the perps to be filled with mortar or words to that effect.
