Treatment Types and Hazard Classes

CCA: Wood treated with TANALITH C (CCA), a waterborne copper chrome arsenate preservative, can be specified for a wide range of applications, for example – roofing, general construction, decking, fencing, garden and leisure timbers.  For marine applications (Hazard Class H6) a dual treatment of both CCA and Creosote is used.  TANALITH C CCA offers comprehensive protection (medium to high risk) against wood boring insects, termites and fungal decay.  Due to the copper base ingredient of the preservative, the treated timber is light green in colour and is leach resistant.

CCA treatment can be administered for hazard class H2 - H6

Tanalith E (Wolman E): Wood treated with TANALITH E, a water borne preservative manufactured out of recycled Copper and Azole Biocides,  can be specified for all above ground, in ground and fresh water contact applications (H2 to H5), where there is a medium to high risk of fungal decay or insect attack.  This treated timber is light green in colour and is well suited to environmentally sensitive applications and close human contact, for example – hand rails, decking, fencing, garden leisure and playground timbers. 

Tanalith E (Wolman E) treatment can be administered for hazard classes H3 - H5

Boron / FLAMBOR: FLAMBOR is a dual-purpose aqueous chemical system that contains both a borate-based wood preservative (TOPRO 94) and a phosphate-based fire retardant (FYRCON) for timber treatment.

FLAMBOR provides permanent and wide spectrum protection against biological attack and also
imparts a high degree of fire retardation to timber when properly treated. FLAMBOR is primarily used for interior applications (Hazard Class H2) but can be used exteriorly above ground (Hazard Class H3) provided that a waterproof coating is applied and maintained. Boron-only treatment is available for applications which do not require fire retardancy.

Boron / FLAMBOR treatment can be administered for hazard class H2 (H3 with a water-proof coating)

Creosote Creosote has been used since 1948 as a heavy duty wood preservative. Creosote is obtained from high temperature distillation of coal tar. Pesticide products containing creosote as the active ingredient are used to protect wood against termites, fungi, mites and other pests that can degrade or threaten the integrity of wood products. 

Currently, creosote is used for commercial purposes only; it has no registered residential uses. Creosote is a restricted use pesticide that can be used in outdoor settings such as in railroad ties and utility poles. Indoor applications of creosote are prohibited as well as application to wood intended for use in contact with food, feed, or drinking water. 

Creosote treatment can be administered for hazard classes H4 - H6

Pacsayf Pacsayf is an aqueous fire retardant chemical solution for the protection of timber. The chemicals in this product react chemically with the wood, preventing leaching, to form esters, resulting in a new timber /chemical compound.

Pacsayf is used extensively to protect timber used as underground supports in the gold and platinum mining sectors.

Timber is treated by submerging packs and props in the Pacsayf solution

Pacsayf meets the stringent specifications for underground health and safety requirements with respect to corrosion, skin sensitivity, effects on gold extraction, effects on water pollution, timber ignition, leaching, timber strength, and a minimum 50% reduction in heat contribution.
