Wooden paving is primarily used outdoors in garden path or terrace areas, its load-bearing capacity is generally not sufficient for trafficked areas. It is important to have a load-bearing subsoil that can seep away or drain water well to prevent waterlogging. The wooden paving blocks lie in a bedding of sand and gravel, the paving itself consists of round, polygonal or square or rectangular wooden blocks. The end-grain surface serves as a walking surface. In contrast to use in the living area, the blocks are impregnated with wood preservatives in most cases. However, the service life of wooden paving is significantly reduced compared to other paving materials. Depending on the type of wood used, weathering, dimensioning and stress, a lifespan of about 15 to 20 years can be assumed for domestic woods, and up to 50 years for tropical woods. Since wood is a very absorbent material and in order to avoid constraints, sufficient joint widths must be provided between the paving timbers.
Preferred wood species: European woods such as oak, robinia, larch, spruce, fir, but also Douglas fir and tropical woods. When using tropical woods, pay attention to the FSC label for wood from ecologically sustainable and socially acceptable forest use.
Height of the blocks for outdoor use: about 10 to 25 cm. The higher, the more load-bearing the pavement.
Standardization: None (the regulations that address wooden paving refer to the use of the paving indoors).
