The safest way to dispose of landscape timbers is in a landfill that has a protective liner to prevent seepage of contaminants into the soil. Landscape timbers are pressure-treated wood that contains high levels of arsenic.
Landscape timbers can be recycled by transforming them into raised bed for gardens. They also can be given to friends and family that may need them.
no, not chemical treat ed
Cherrytone landscape timbers are untreated wood, coated with a factory applied stain. they are NOT redwood!
Landscape timbers aren't recommended to build your fence because most of them are not made to support loads or to be in contact with the ground. It depends upon what it's treated with... So...yea it seems to be a cheaper solution, but it will yield cheap shortlived results. - Nikki T - Texas
They are loaded onto carts and closed in a large vessel where liquid with the active chemicals is pumped in at high pressure to force the liquid into the wood. There are two different ways it is done. The way that is used for building materials starts with kiln dried wood and land scape timbers are generally done wet. What this does is not allow as much treatment into the landscape timbers and they will rot sooner. You may see "treated to refusal" on the landscape timbers. This means they pressurized the vessel, but due to the water already in the wood the treatment did not reach the core.
Structural timbers are those timbers used in the construction of a building that are "load bearing". They are the timbers placed under stress by and that support the weight of the building.

PLantation timbers are timbers from planted forests, that is humand planted them Old growth forests are the natural ones.
I'm assuming by 20' circle you mean 20' diameter. And I'm assuming only one layer of timbers. 3.14 x 20 = 63 feet of timbers needed / 8 foot long timbers = 8 timbers, for a 20' radius circle, double the number of timbers, and for each row of timbers increase the number of timbers accordingly. The closer to circular you want you'll need to cut the timbers shorter. 8 timbers will make an octagon (like a stop sign)
nothing :D
Native timbers are simply timbers that are found locally. Native timber can also be 'second growth' timber, which means that it is sustainable.
Tar is used to protect the timbers from weathering.
