Landscape Timbers. Even though t- posts can last a long time, they typically aren't as stable once set in ground in comparison with landscape timbers , but that has a lot to do with quality of the ground. Timbers can also be nailed in a crossbar pattern which helps strengthen the whole structure more. Treated landscape timber will rot due to fungal attack This fungi attack causes the treated wood to soften and starts to decay. As you build wood sleeper retaining wall, it is wise to scrutinize the timber and make sure it is free from fungi damage.
Placing inch spikes in the timbers helps to stabilize them as well. Mark where you plan to install the front edge of the edging with a pair of stakes and a string. Dig a trench approximately 3 or 4 inches deep with a shovel. Set the landscape timbers in the trench.
Measure the length of any timbers you need to cut. Rebar, ribbed metal rods used in building construction, is one method used to hold landscape timbers in place and secure then to the ground. Mark the footprint for the new timbers using spray paint of construction caulk. Secure the corners together using screws designed for pressure treated wood. Wood: The best woods to use for edgings are redwood and cedar because they don't rot. Pressure-treated lumber is most rot-resistant. You can also paint wood preservative onto untreated wood.
Basically, you build a little underground fence with lumber. A pressure treated softwood sleeper will have a maximum useable lifespan of 10 years, and in many cases — and particularly in exposed coastal locations — this can be as low as two years. Compare this to an oak sleeper and the difference is staggering. Like all wood , sleepers will eventually rot and fade when exposed to the weather.
To prevent them falling to bits before their time, you need to use a good wood preserver. It should be stressed that building a house from landscape timbers provides great flexibility. The structure can range from a small cottage or cabin on the lake, or in the mountains, or a residence with sq. Because the timbers are each 8 ft. Another way to defend against rot is to try to form a protective barrier in between the treated wood and the soil.
Drive the rebar flush with the timber face, then use an extra piece of rebar as a punch to drive the installed rebar slightly below the wood surface for safety reasons, you don't want any metal sticking up above the wood. Note: Be careful not to drive rebar anywhere there may be underground sprinkler lines.

This is called a full sawn dimension. Now two-by-fours are rough cut, then dressed or smoothed down, before they are sold.
Full sawn lumber is the nominal size. For larger, almost square sizes, the width and depth might be averaged. An eight-by-eight full-sawn landscape timber -- 8 feet long -- is really 9 inches deep, 7 inches wide and inches long, so it's close to standard railroad tie size. Landscape timbers come in a variety of sizes other than the original railroad tie size.
Three-by-three landscape timbers are available, as are four-by-four and six-by-six. Sometimes landscape timbers have square corners, and sometimes the corners are rounded.
