Timber Treatment

The softwoods used for fencing timbers are sourced from responsibly grown well-managed forests. Being a natural material, made from cells of sugar and fibre, softwood timbers can be susceptible to rot and decay organisms as well as insect attacks.

Modern wood preservatives are designed to make the most of and protect softwood timbers in a wide variety of end uses, but particularly those in high-hazard applications such as in-ground contact (UC4 – Use Class 4 – EN 335).

The wood preservative Impra is forced deep into the vulnerable sapwood cells of the softwood timbers under a proven high-pressure treatment process. The incising also allows a deeper and more consistent penetration of wood preservative into this critical zone of confidence. The resulting preservative-treated timbers are high-performance products with assured long-term protection against decay and insect attack.

M&M Timber is an approved WPA treater. Timbers are FSC Certified and are backed by the independent WPA Benchmark accreditation. The WPA benchmark scheme relates specifically to the durability (resistance to biological degradation) of wood treated with preservatives by an industrial impregnation process. It applies specifically to a treated product such as a post. Products certificated under this scheme are verified as being compliant with BS8417, the wood preservation code of practice.
