I am pulling together a list of materials for the wall construction and have a few questions regarding the width of the DPC layer. The wall construction is cavity wall in 100mm blockwork pebbledashed externally with a suspended timber joist floor internally.
What size DPC should be used in the following instances (standard products from Selco)
1) Outer skin of 100mm blockwork - Is 112.5mm correct selection to accommodate for the block plus pebble dash?
2) 215 solid wall element - Is 225mm correct selection to accommodate for the pebble dash
3) Inner skin of blockwork - Will the 112.5mm work or should i go wider and lap down behind the timber wall plate?
4) Above openings where cavity wall lintels have been installed for cavity tray - 600mm
As always your knowledge would be much appreciated.
