When wood is to be laid in an area that is outdoors, wood preservation is a design that minimizes exposure to water in the water.
But it is also important to ensure that wood tiles, which are excellent for a structure with water drainage, are made of a wood, which opposes the water resistance. For this, the wood tile made of acacia wood can be perfectly suitable. Wood tiles are sometimes referred to as floor grids.
What is acacia wood?
It depends on which wood the wood tile made of acacia wood really consists. When referred to as acacia, wood tile or floor grating may be acacia imported from Australia to Indonesia, Malaysia, Thailand, and Vietnam, where it is grown for papermaking and timber production. It is often imported to Germany from Germany, where it is cultivated on plantations. The manufacturer's information here speak of a hard and durable type of wood, which should be suitable for outdoors. The floor grids are often not treated with wood preservatives, but only with wood oil. It is then recommended to continue to treat the floor covering with wood oil on a regular basis to protect and preserve the wood. The wood is available from cultivation on plantations, which were created according to the FSC rules for sustainable timber industry.
Also sold are wood tiles made of gold acacia, such as iroko or burma teak also called. This wood has nothing to do with the real acacia, it is rather an African teak wood. Even this wood is a good choice for outdoor use, almost all teak wood is one of the hardwoods, which can offer durability class 1 or 2. Here, however, you should assure yourself of legal origin, see below.
If the wood used is simply called acacia wood, but is designated as native wood, it probably will not be acacia wood either. The real acacia is found in tropical to subtropical areas of the world, in our latitudes it would not survive, because it is not hardy. So it will probably be robinia wood, because the robinia is also called mock acacia or false acacia. Originally from North America, it was first planted in parks and gardens with us and is now wild and found in forest plantations. This wood is very suitable for outdoor use:
Advantages of Robin Wood
The sturdy tree, which is also popular in sandy areas to reduce soil erosion, provides a very weatherproof wood. With durability class 1 - 2 it is granted a life expectancy of up to 25 years, if it is installed without permanent earth or water contact. This is a good choice if you choose the wood tile that you have selected, called acacia wood, that is, Robinia (botanical name Robinia pseudoacacia). It does not even need a coat of wood preservative, so the wood tiles are often get oiled.
