Hi, I previously posted regarding spalled lintels in a No Fines concrete house. I engaged a structural engineer regarding replacement of these. However I would appreciate your advice as to the best way of building the replacements in. The SE has specified a replacement which is 210 in height as opposed to 250 height of the original. He has specified that the top of the lintels (3m and 2.5m long) be packed with slate and a 'dry' mortar mix. I reckon a better/ easier option would be to lay a mortar bed along the full length of the top of the lintel, jack this up tight to the No Fines concrete and then pack the bearing surfaces (200mm) with slate and the 'dry' concrete mix.
Any thoughts/ opinions, as usual greatly appreciated
thanks
