Which means treated wood is not able to repel water. But generally, a wood preserving treatment does not waterproof wood. In some cases, treated wood may have also been infused with a water-resistant chemical coating. Treated landscape timber is less likely to rot, thanks to those wood preservatives. But Isn’t Treated Wood Less Likely To Warp? All of that drying out will severely contract wood, causing timber to warp and crack. And, as the water evaporates, wood will dry out and shrink. Now, when wood soaks up water/moisture/vapor, wood expands. From moisture in the ground, to the humid vapor in the air, wood can soak it all up like a sponge. Hygroscopic materials are incredibly good at soaking up water from the environment around it. You see, wood is ‘ hygroscopic’, which is a formal way of saying that wood is super-absorbent. All of that water can make wood shift around. Well, the problem stems down to the moisture in the soil (and the rainfall from up above). But, What Causes Wood To Warp In The First Place? Indoors, water can splash back onto wood if it’s close to a water source like a sink in a bathroom.Whilst outside, water saturation is usually because of rain and dew. Now, how the wood absorbs moisture varies (depending on where it is situated). Warping is always due to too much moisture, no matter what type of wood you’re using. So, water can still soak into wood, and cause it to warp, if that treated wood is left unsealed. However, these preservatives do not waterproof wood. These preservatives stop wood rot and decay. Well, the aim of wood treatment is to infuse wood with wood preservatives.

Or, it can be preserved using Micronized Copper Azole.Īnd as a result of these treatments, (particularly in the case of micronized copper azole treated wood), landscape timber can appear a bit green.
When it comes to landscape timber in particular, the wood is treated with either Alkaline Copper Quaternary Ammonium. Regardless, treated wood is much more rot-resistant, and far less likely to decay.

This treatment involves infusing wood with chemical preservatives (referred to as pressure treatment). Wood used for any kind of outdoor structure will have been specially treated to protect it from decay. Related Posts: What Are Landscape Timbers Treated With?
