European Hardwood Mats
GJ Bog Mats use high quality, hard wearing, durable Oak and Beech for their European hardwood bog mats. They can tolerate repeated use and provide the ideal protective material for temporary roadways causing minimal disturbance to the ground.
European hardwood mats made of Oak
European Oak otherwise known as Quercus petrea, Quercus robur or European White Oak is one of Europe’s dominant broad leaf species. They grow to a lofty 20-30 metres high and achieve a diameter of 40-80 centimetres. The timber is straight grained, hard, heavy and robust.

European hardwood mats made of Beech
European Beech otherwise known as Fagus sylvatica, grows in the west at altitudes of up to 1500 metres. They reach a height of 35 metres and achieve diameters between 40 and 90 centimetres. The timber is finely textured, heavy and exceedingly strong.
