CCA (Copper-Chrome-Arsenate) is an industrial wood preservative and is widely used in South Africa. When applied to timber it enhances the durability by preserving it against biological deterioration such as insect attack (wood borer and termites) and fungal decay (rot). In South Africa only CCA Type C is allowed to be used as it is internationally recognised as the most stable and effective type, i.e. apart from its efficacy as a timber preservative, it successfully fixes to the lignocellulose material in wood. CCA may only be applied by industrial high pressure process from where the familiar term “pressure treated wood” hails from.
