Experimental evaluation of water tightness of single leaf walls


The use of thick single leaf envelope walls can be an interesting solution in some Mediterranean countries like Portugal, as an alternative to the cavity walls. In the single leaf solution the rain watertightness is fundamental. The results of some tests made to evaluate experimentally the rain watertightness of this kind of walls are presented. Ceramic and lightweight concrete units have been used in the walls, which have been rendered. A large chamber have been used to perform the tests. One of the walls has been tested after an accelerated ageing test.
