Jeffb Posted June 26 Share Posted June 26 Hi all , I have an area that will be a patio that requires the levels raising , my question is, is it ok to use the waste off cuts from the light weight internal wall locks like a thermalite block ? Will these off cuts degrade in time and crumble to nothing ? I have approx 8m x 3 m to built up by 300mm . I will also use my old roof tiles and any of the concrete block off cuts etc then crushed concrete over the top. I will probably only be able to use a walker plate to compact the area. Any ideas any one? Thanks Jeff Link to comment Share on other sites More sharing options...
Dave Jones Posted June 27 Share Posted June 27 a few mixed in wont hurt but you dont want all of it. They hold onto water which come winter time the frost turns them to dust over time. 1 Link to comment Share on other sites More sharing options...
