UC4 Timber Preserving Treatment

UC4 products are manufactured using only redwoods treated at a moisture content of 28% or less. The solution strength of the preservative is significantly higher than on standard pressure treatments and the vacuum/pressure process is longer and more thorough than standard treatment cycles, allowing for much deeper penetration of the preservative into the timber. Standard non dried pressure treated products have a shorter expected service life, whereas our UC4 products that are treated against fungal decay and wood destroying insects have a desired service life of 15 years. The entire treatment process is quality assured in accordance with ISO 9001 criteria, and regular sampling and analysis ensures treatment standards are maintained at all times.
