I have just had a builder install some padstones and RSJs for some new openings in a cavity wall. I am concerned about the installation for a few reasons. 1. He has installed the padstones (220 x 200 x 100) sideways so that they span the cavity. I guess this is good for load spreading, but I am concerned as I am unsure whether they are supposed to be used side on, they are bridging the cavity and their now 'top' don't seem to be a smooth as their side faces. This means that the RSJ is in point contact with the high points of the padstone (not evenly spread load). 2. The padstones are off level. I'm sure this can't be right. I guess it could be dry packed between the padstone and lintel, but seems like a bodge. 3. The mortar under the padstones has been packed with broken brick. I'm not sure if this is a problem, but would really appreciate some expert advice as he is sending through an invoice this evening.
