It is also used aesthetically to border a property intermingle with hedging and other foliage and can be used to create enclosed arena to train young horses. What makes our product unique is its ability to sustain our damp climate for a significant length of time without compromising it’s intended use.

Treatment Process

We use 2 methods of treatment which are designed to impregnate the treatment oil into the cells of the timber under high pressure conditions. Our timber products are inserted into our pressurised treatment vessel through a rail and bogey car transport system. The vessel doors are sealed and the treatment cycle commences using high pressure pumps, initially using air pressure to open the cell membrane of the timber to facilitate the transfer of the treatment oil into the timber.

Creosote is our most popular treatment oil and is transferred to the timber through a high pressure and heat carrying system designed to achieve full sapwood penetration. A treatment cycle will vary from 5 to 11 hours depending on the customer specification.


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.
