Just a question, if it is thermal expansion, what could cause it to make a thud, I would have thought slab thermo expansion/contraction would run along the full bearing length of the slab on the brickwork, and not be localised. What you have described sounds familiar (excuse the pun) in cases where Steel composite structural flooring is used? Hence the need to check the certified engineering drawings against the As Built Daven Reason for asking the noise is a precise sound and in a very specific location, without opening the ceiling I can by standing under the area almost narrow it down to a metre in from a corner. Its almost like an impact of a hammer, but a hollow thud (amplified by space in ceiling), not a crisp knock. Are you able to remove a light fitting or drill and small inspection hole into the ceiling and use an Bosch Cordless Inspection Camera Daven I should have mentioned that I am a structural engineer, problem is I have not practiced in 30 years, so very short on current knowledge. Good to hear then you will have no issues in solving the problem as the science/math is still the same. OT, I often use FEM Multiphysics simulation presentations and Bim data in illustrating problems and fixes IMO it is the data collection,technology and BOSCH tool applications that has made the real impact. I am keen for you to find a resolution leave a PM or email appsb4UBuild (at) gmail Cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Thud (knock) noise coming from area between ceiling and 9Aug 31, 2020 9:28 am Daven, I have the exact same issue!!! It is so hard to explain it to others but Iām glad you have! We have just moved to a new apartment block and have the same knocking sounds since we moved in. It has gotten worse week after week. The builders guys are around and trying to identify the issue however are still scratching their heads! Have you had any progress in identifying your source?
