You sent a flexible wall detail but I have a rigid wall? Tested Detail Queries

Test results obtained with flexible supporting walls may be applied to concrete or masonry elements of an overall thickness equal to or greater than that of the element used in the test. This rule does not apply pipe closure devices that are positioned within the supporting construction unless the length of the seal is increased by an equal amount and the distance from the surface of the supporting construction stays the same both sides.
