Pipe Penetrations

  • Use Monarplan pre-fabricated pipe fittings where possible.
  • Remove any existing lead flashing, old paint, and rust where applicable and clean surface to receive membrane flashing.
  • Cut pre-fabricated pipe fitting to the appropriate pipe diameter and slide into position.
  • Install mastic sealant between the Monarplan Pipe Fitting and the pipe and secure with a stainless steel clamping ring (eg. jubilee clip).
  • Where pre-fabricated pipe fittings are not practical, wrap the pipe with unreinforced Monarplan PVC D in accordance with the appropriate detail.
