Proposal

Following an internal pipe water leak in May 2025, it has been recommended by a structural engineer to install washers into the ceilings based on the following:- Given the above findings and conclusions I recommend that ceiling restraint fixings are installed throughout the damaged section of ceiling within both rooms. I have appended a sketch showing a typical detail of such restraints. These restraint fixings should be installed to all areas where water damage occurred as soon as is practical and certainly within the next three months. I recommended that the fixings be installed at 900mm spacing along the length of each joist, but that the spacing is offset between adjoining floor joists so that the fixings are at no more than 625mm apart in damaged areas. In the temporary condition the washer could be face fixed to the underside, but to ensure that the fire resisting integrity of the ceilings are maintain the washers and screws should be recessed into the plaster surface to prevent them acting as a heat sink and failing before the end of the required fire resistance period. All cracks in both ceilings should be fully repaired by cutting out loose sections and using plaster repair compounds and fillers to ensure that both ceilings are effectively airtight.?
