Preserved wood

For preservation purposes, wood is treated with chemicals (biocides). However, for this purpose you may only use authorised wood preservatives, in order to prevent any unacceptable damaging side effects for humans, health and the environment. The Board for the Authorisation of Plant Protection Products and Biocides (College voor de toelating van gewasbeschermingsmiddelen en biociden or Ctgb) determines which products are authorised in the Netherlands.

Creosoted wood and CCA wood

Creosoted wood and wood impregnated with a copper-chrome-arsenic (CCA) may no longer be purchased for private use.
