Timber is still our most versatile and adaptable construction material. A warm, attractive and cost effective product, it is easily worked for a wide range of end uses and has a tremendous natural strength.

Yet timber can be made to perform to even higher standards. Properly protected against the risk of decay and insect attack it becomes a very durable product. Vacsol Aqua treated timber from Wyckham Blackwell has been impregnated through the Vac-Vac process with Vacsol Aqua wood preservative to give it this extra advantage.
