Is the recess indicated in the raft detail of the timber separating walls required for acoustic reasons?
The round recess indicated in the concrete raft foundation shown in detail 7 of E-WT-1 and E-WT-2 is provided to enable moisture to be drained from the cavity of the separating wall to the outside of the building. The recess is shown for illustrative purposes and is not related to the required acoustic performance of the robust detail, for the purposes of Building Regulations Part E Requirement E1. Accordingly, other Building Regulations or standards, which are outside our remit, would need to be considered in relation to this issue.
