Agrícola y Comercial Mardones y Compañía Limitada (Mardones), since 1978 has been largely the most relevant railway sleeper supplier in Chile. Understanding its key role in the railroad and forestry industries, in 1998 Mardones decided to build a creosote wood impregnating plant considerably extending the sleeper service life.
Creosote vacuum pressure timber impregnation is a proven process widely used in North America, Europe, Africa and Asia to waterproof and immunize wood against environment natural degradation, increasing the wooden sleeper life cycle several times.
With the abovementioned purpose, Mardones created a joint venture along with the American company The Burke-Parsons-Bowlby Corporation (BPB), by that time a major railway sleeper producer in the USA, thus founding Mardones BPB Creosote Treaters S.A., a Chilean enterprise that invested more than 4 million US dollars in this plant’s infrastructure and sleeper inventories. Nowadays Mardones – BPB serves all the Chilean railways and has also exported oak creosoted treated sleepers to Egypt, Saudi Arabia, New Zealand, South Africa, South Korea, Colombia, Costa Rica and Peru, having annual sales up to 10 million dollars, equivalent to more than 200 thousand sleepers sold per annum, producing in the last 20 years the quantity of 3.4 million of sleepers valued in 138 million dollars.
