All of these Nashville Retaining Walls can be used for the same situations, but each one has its limits. But today I will talk about wooden retaining Wooden retaining walls. these would be the most basic of walls to build and also one of the most versatile walls also. Every time we build a retaining wall we look at the situation and the required use and also the soil type. You will need to do this on each wall you build, and build each wall using that information you have.
The basic layout for a wooden retaining wall:
You will have wooden posts and wooden rails which will hold back the soil. Behind the rails you will need a perforated pipe to collect and drain any water and drainage metal to allow water to move behind the Retaining Walls in Nashville and also keep the water away from the wall. This is very important to have enough drainage behind the wall due to the fact if you don't, it may push over with a build up of water.The materials used for a wooden wall will vary depending on the height and use of the wall. As a rule of thumb we all ways keep the post spacing at no more than 1c, and also a min of.075mm of 20mpa structural concrete around the post. the smallest post that should be used for up to 1m high wall should be 125x125 h5 post. And the size goes up from that. Also the depth of the post in the ground should be the height out of the ground should be in the ground. Example: A wall 1m high should have the posts at lest 1m in the ground. Now if that same wall was to have a car park on top of it then it would need bigger posts and also deeper posts to carry the surcharge.
The rails can just about be anything you like as long as they are the correct ground treatment and span at least 3 posts. The correct treatment would be h4 - h6, depending on the use of the wall. Again as a rule you build the wall level and if the ground behind the wall sloppes away then you cut the top rails to the same slope or you can step the wall at a post. Each rail will need to be nailed to the post to hold in place. We use 150x50 for the rails, so we use 2x 90mm-100mm galvinised nails.
Drainage behind the wall:
Now this is very important and must be done right. We use 110mm punched (has holes in it) drain coil and a graded drainage metal 25mm-7mm in size. the drain coil should be place below the bottom rail so any water stays behind the wall. Place the drainage metal on top of the drainage coil and fill up behind the wall. The drainage metal should be a min of 200mm thick behind the wall. And of course you should run the drain coil to the place that you take the water, this may require a little extra digging to make the water run the right way.
Now that's the basic nuts and bolts of how to build a wooden retaining wall.
Wooden walls have a maximum height of around the 3m mark with an engineer's input and geo report on the ground around were you want to put the wall. And will require some big machines to bore the holes and lift the poles in. Also surcharges on walls, these require engineers or a tradesman to look at it.
