Pressure Treatment of Wood information on the Preservatives used for pressure treatment of wood guidance note and regulations
How to plant a pole – guidance note The process of proper preservative treatment of timber requires for the preservative to be deeply impregnated into the permeable or treatable sapwood, resulting in a deep envelope of preservative treatment around the central and inner impermeable or untreatable heartwood. It is preferable that timber is purchased in the size and shape in which you intend to use it.
Preservative treated wood – the sutainable choice. Wood offers a simple way to reduce the CO2 emissions and carbon storage effect.

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.
South African Standards SANS 1288, SANS 457-2/3 and SANS 753/4 specify the marking requirements for any preservative treated product that claims to comply with the respective Standards. The following information must be contained in the marking: a unique plant identifier or trademark, product certification mark, SANS standard designation, a hazard class, date or year of manufacture of poles…
An important consideration when building with timber is predicting how long the structure will last. Whilst insects, decay or rotting organisms and marine borers can all attack wood, some timber species have the ability to resist attack better than others. The natural durability of a species to resist attack by wood destroying organisms is an indication of how long that timber will last when it is exposed to a defined set of exposure conditions without any additional preservative protection. The natural durability of timber species varies, even so within the wood from the same species of tree, depending on whether its sapwood or heartwood.

There are two regulations in South Africa that apply to wood preservation. Both these regulations refer to compliance of SANS 10005, and in order for the reader, end-user, specifier, regulating authority etc. to fully understand the interpretation or intent of each regulation, one needs to read it in context with the relevant clauses given in SANS 10005, The preservative treatment of timber. SANS 10005 (previously SABS 05) is the code of practice that was developed many years ago as a guidance document on all matters pertaining to wood preservation, i.e. wood preservative types, processes, methods, treatment requirements, hazard classifications, reference to the relevant product specifications, handling precautions etc. SANS 10005 is commonly referred to by industry as “the bible” of wood preservation…
