If you wish to construct some wooden retaining walls, then you may need to add some corners to the edge of your landscaped area. This is true for wooden retaining walls which will be fitted around flowerbeds or box hedges, for example, or for any large area of landscaping which has a straight edge. Installing a corner when constructing a wooden retaining wall is not too difficult, and you should be able to manage to complete this without too much difficulty. If you have the right equipment to install a wooden retaining wall, then you should also be able to fit corners into the landscaped area without too much difficulty.

Step 1 - Plan out the Wooden Retaining Walls

The first thing that you will need to do is plan the position and length of your retaining walls. Mark these out on the ground using a tape measure, and then positioning a string with a peg along both of the walls. The pegs should cross over at the edge of the landscaping area, and this is where your corner will need to be. Install a metal post at the edge of this corner.

Step 2 - Assemble the Walls

Make your Walls, bringing them as close together as possible. Leave about 1 foot of wood at the edge of each corner for large wooden retaining walls, and 1/2 foot for smaller walls. Take one of the wooden posts which you would use to support your timber, and place this in the very corner. You may need to position this using a spirit level. Drive it in deep enough so that it can stand upright by itself.

Step 3 - Add the Timbers

Take your timber slats, and extend them into the edge of the wooden post. You should then cut them down until they just touch the slats on the opposite side of the wall. Nail the slats to the relative sides of the post, making sure that they are held firmly in position. Add at least 2 nails to each piece of timber in order to hold it tightly to the side of the post.

Step 4 - Finish the Wall

Allow the wood to settle into position overnight, and then install some brackets against the metal post. These should hold the metal against the wooden post, and then extend on either side, being fixed to the lumber by a few screws. Add at least 3 of these brackets at the top, middle and bottom of your retaining wall. Make sure that they are held securely. When you have added the metal brackets, you should paint the wood with a coat of water-proof varnish, covering all the surfaces with at least 2 separate layers. Leave this to dry, and then paint the wood in order to give it an additional protective layer.
