Treatments and Building
As of August 2009, structural pine timber and other softwoods used in Restricted Movement Zones (RMZ) must be treated.
Advisory Note 2009/002 issued by the Building Commission gives the following advice:
“Susceptible timbers (pine and other softwoods) used in areas infested with EHB must be treated to ensure durability, or non-susceptible materials must be used. An infested area is defined as a Restricted Movement Zone (RMZ).
Where pine is used as a primary building element in an RMZ, it must be suitable for hazard level H2 or higher (refer Appendix C of AS1684.2 for more information)”.
Advisory Note 2009/004 has also been issued by the Building Commission as supplementary information to Advisory Note 2009/004.
