Question:
Question:
Is it necessary to provide a dpc under timber soleplates to internal partitions built off concrete floors?
Is it necessary to provide a dpc under timber soleplates to internal partitions built off concrete floors?
Considerations:
NHBC Standards clause 6.2.10 states that ‘dpcs should be installed below all ground floor walls including internal partitions, to protect timber from rising damp and residual construction moisture’.
Not documented in the Standards.
Answer:
A dpc should be provided under all timber soleplates. However, if residual moisture in the construction is low due to the type of construction used e.g. beam and block suspended floor and the floor has been well protected from the weather, then it would be acceptable to omit the dpc.
