LOSP Timber Treatment Facility

Dindas LOSP Timber Treatment Facility

One of the largest timber treatment facilities in Australia

Our treatment facility is one of the most extensive treatment facilities in Australia. Dindas treat timber and engineered wood products, but we also provide custom treatment services for many merchants and wholesalers. The facility is the only Queensland based treatment plant that offers a clear H1 & H3 treatment that requires no re-drying or impacts the stability of dimensional size after treatment.

LOSP Timber Treatment Compliance AS1604

Dindas completes regular independent tests and audits via our treatment chemical supplier Koppers Performance Chemicals. Each charge is assigned an individual charge number and has a treatment certificate issued. Our treatment plant operators audit each charge to ensure schedules achieve the required uptakes. Koppers Performance Chemicals have a representative attend the site regularly to review products treated in the previous weeks.

Safety and the environment

All visitors, contractors and employees are inducted to our site before undertaking any work. Dindas is committed to working safely and playing our part in looking after the environment. Dindas completes groundwater sampling and environmental audits twice yearly to ensure our treatment process has a minimal environmental impact. All plastic removed from contract treatment packs will be recycled rather than put in landfills.
