Timber preservation refers to the chemical treatment of timber for durability against fungal decay & attack from insects, such as termites and borers.

 The most popular timber treatment, with the longest & most reliable in service record. Water borne Copper, Chrome & Arsenic compounds are impregnated into the timber under a vacuum/pressure cycle, the timber is held for  a drying period where the chemical 'fixes' within the timber cell walls.

ACQ This process is very similar to CCA, but relies on copper properties as the active constituent. (Alkaline, Copper Quaternary)
