What treatments do you offer?

We use 2 types of treatment oil, Creosote (our most popular), and AC500 (Tanalith) which are designed to impregnate the treatment oil into the cells of the timber under high pressure conditions. Please contact us directly if you require products treated in AC500 as we primarily treat to order for these products.

What is Creosote?

Creosote is a category of carbonaceous chemicals formed by the distillation of various tars and pyrolysis of plant derived material, such as wood or fossil fuel.   The major chemicals in coal tar creosote are polycyclic aromatic hydrocarbons (PAH), phenol and creosols.  Creosote is also a pesticide.

Are your products responsibly sourced?

PDM adopts the PEFC standard with respect to the sourcing of its wood raw materials.   PEFC stands for Programme for the Endorsement of Forest Certification, and our commitment to this standard demonstrates our drive for sustainable solutions in our material sourcing.  Sustainable forest management certification assures that forests are managed in line with challenging environmental, social and economic requirements.  A Chain of Custody certification tracks forest-based products from sustainable sources to the final product.  It demonstrates that each step of the supply chain is closely monitored through independent auditing to ensure that unsustainable sources are excluded.

What quality assurances do you provide?

Besides our commitment to sustainable sourcing through PEFC certification, PDM’s products are also certified to IS 435 and IS 436.  We pay a lot of attention to our supply chain to ensure that we have a consistent grading of product to meet market needs.  Our quality team regularly visit our suppliers to ensure our exacting standards are being met.

What warranty is provided on your products?

We offer a 15 Year guarantee on creosoted products. If it is proven there has been a failure, within this period, due to the treatment process we will replace the affected product or provide a full refund.
