Timber is the only one organic building material. It does not loose its natural qualities even after final mechanical and chemical processing, if done according to our technologies.
We can offer universal method and universal material. Our timber products are impregnated by depth-vacuum method using German manufacturer's impregnation material "Wolmanit CX-10". Pressure treatment allows the wood preservatives to penetrate deeply into the wood with a perfect distribution thus providing optimum and long-lastingprotection for your wood. That is why our articles are resistant to any atmospheric influence, mould-resistant and insect-resistant. Treatment with "Wolmanit CX" in tank ensures durable protection against fungi (including slime mould formation) and insects.
For decades, chromium and arsenic were the only choice for wood treatment in tank. Now we offer "Wolmanit CX" – a chromium-free protective product. Extensive toxicological testing has confirmed the advantages of copper-HDO in term of health, workplace safety and environment compatibility against preservatives containing chromium and arsenic. For this reason, the "Wolmanit CX" products are based on copper-HDO. To us, this is of great importance, because the "Wolmanit CX" products do without materials that can damage our environment and human health. "Wolmanit CX" satisfies all the requirements applying for a modern-day, environmentally compatible wood preservative: from initial processing right through to final disposal. This has been confirmed in many tests and official certifications – European Standards, DIN, CTB P+, etc.
"Wolmanit CX" is forced deep into your wood during the pressure treatment and levels it coloured green. Just small amount of preservative are sufficient to give your wood lasting protection in contact with the ground. The active substance content of "Wolmanit CX" is free times lower than that of traditional, chromium-based products.
Impregnated wood has natural green colour and you do not have to paint it. In the same way, as time goes on, the wood takes on a silvery grey colour which is a result from the exposure to ultra-violet rays. But this does not affect the quality. If you prefer to personalize them with colour, you can also pain them. On the other hand, with colours you can get very surprising results.
We give 15-year anti-rot guarantee on all wooden products that are pressure impregnated using "Wolmanit CX". It is however to be remembered that timber is a natural product, a living material and is subject to movement and weathering as it seasons. Don't worry if cracks appear. It is not uncommon for small splits to occur in timber when drying and warping can occur when timber is allowed to dry too quickly. These will normally go back when humidity increases. This is the hand of nature at work and should not be considered as a fault in the product.
