If you’re not sure how to begin, the following steps will guide you through the process. Dig a deep enough trench, stagger the joints of the next row of timbers from the previous row, and add drainage stone behind the wall. Once the wall is up and in place, install railroad ties to act as a footing. Once you’ve completed these steps, you’ll be ready to build your retaining wall.
Stagger the joints of the next row of timbers from the ones below
To start building a retaining wall, place the first course of posts at least four feet apart. Space them four feet apart so that the joints of the next row of posts are staggered from the previous row’s. Next, place two-by-four string holders. They should be placed four feet apart from each other so that they will be level and plumb. Hammer 60d wall tie nails through each post and the string holders.
You can also stagger the joints of the next row of timber by placing them about an inch away from the ones below. This will greatly help the stability of the wall. To build a retaining wall, you should have approximately a quarter-inch of each timber extend past the joint. If you have eight-ft timbers, you should space them two feet apart. To get the best results, you should stagger the joints of each row by half-inch.
After laying the first row, you should lay the second row. It is very important to have the first row level. If you are unsure of the level, use a level and check the alignment of the previous row. Then, begin building the second course by placing additional blocks. You can also use a running bond pattern. This involves layering the stones in an offset pattern that will make the wall more stable. Additionally, this pattern will look much more attractive than laying them flat.
Once the first row of timbers is in place, use a small level to check its level. A four-ft level is useful for ensuring that the timbers are level. A torpedo level will help you level the timbers from front to back, but if you need more height, you can also use vertical posts to hold the top row in place.
Once you have a level surface, make sure to line up the trench with landscape fabric or perforated drain pipe. Make sure that the walls do not encroach onto your neighbor’s property. It is also necessary to make sure that you leave enough room for deadmen and backfill materials. Make sure to allow several feet of space between each course of masonry.
Add drainage stone behind the wall
If you are building a retaining wall, one of the best ways to control water is to add drainage stone behind it. A small amount of perforated pipe should be run behind the wall every 30 to 40 feet to channel water away from the building. You will need to dig a hole in the bottom of the wall to access the pipe. After the stone is placed, you should install filter fabric on top of the drainage stone.
To create a drainage system for your retaining wall, you can install a perforated pipe in the base. It will prevent mud from penetrating the wood and cause problems down the road. To do this, drill a hole every four feet at the center of the lowest full-plank. Then, use a hand saw to cut away any excess timbers.
After constructing the wall, add a layer of landscape fabric to stabilize the soil. When building with 6×6 timbers, remember to add a backfill layer and a drainage layer. To make the wall more secure, you can plant flowers and small plants along the sides. These plants have roots that help hold soil in place and will blend in with the area. Avoid planting trees and shrubs too close to the wall because their roots can migrate to the area of the retaining wall and weaken it.
After you’ve finished building your retaining wall, make sure the base material is well compacted. The backfill is the dirt behind the wall. To make it work effectively, you can use gravel or granular backfill. If you can’t find granular backfill, you can use native soil for your retaining wall. After you’ve installed the drainage stone, backfill the remaining space behind the wall with native soil.
Once you’ve finished excavating the soil behind your retaining wall, you can lay the sixx6 pressure-treated timber in the trench. Use a 4-foot level to check the timber’s level. You can add additional gravel if necessary. Next, drive the 1/2-inch rebar into the holes with a sledgehammer. You can also use a hacksaw to cut the rebar.
Dig a deep enough trench
Before you start constructing the wall, you must dig a deep trench for it at least 8 inches wide and about 12 inches deep. The sides do not have to be straight or even. A trench digger is an excellent choice, but a motorized trencher is a specialty tool that is not always needed. After digging the trench, compact the bottom with a hand tamper.
Once you have dug the trench, you must fill it with wall rock and compact it. Ideally, the rock will be a mixture of sand and gravel or rammed earth. Once the foundation is in place, you must add the fill to the retaining wall. You should cover the fill with a layer of gravel or sand, but not more than 2 feet thick.
To make sure that the foundation is secure, you must dig a deep enough trench to hold the wall. If the wall will be tall, you must dig a deeper trench than the base. The base should be at least 30 cm deep. For short walls, you should dig about six inches down. For taller walls, dig seven inches deep. This will prevent drainage under the wall. Dig a trench that is deep enough to fit the blocks and three inches of gravel footing. Dig the base area as level as possible. Then, ram the trench to make sure it is smooth.
Whether you are building a retaining wall with 6×6 wood or concrete, you should know where you’ll be placing the retaining wall. Always ensure that the retaining wall will not encroach on your neighbor’s property. To prevent this, stake out the property line and make sure there’s enough room to build the wall, deadmen, and backfill material. A retaining wall should be several feet from the property line.
Once the base material is in place, you can use a level to check it. You can also use a level to check where you’ll need to level the area. Next, drill a few holes for the first course of the wall. Drill the posts four feet apart and attach rebar. Make sure the rebar is flush with the 4×4 posts. Repeat the process until the wall is complete.
Install railroad ties as a footing
To install railroad ties as a footing for your retaining wall, you must lay them out on level ground. You can lay rebar on top of the railroad ties and then drill three-inch holes in them to hold them in place. Make sure that all ties are level, as you’ll need to adjust the next ties once the first tie is level.
To install railroad ties as a footing for your retaining wall, you must first prepare the area where you will cut the ties. The area should be at least five-to-six inches deeper than the railroad ties. Fill the rest of the area with gravel. You must also make sure that the ties are in good shape, with no visible splitting or dry rot. You should also avoid tying spikes or plates to them, as these can cause the wall to fall when water is present.
Once you have a level surface, you can add baseboards. The most secure way to install baseboards is by digging down half the height of a tie. This will allow you to bury the bottom railroad ties and make a more secure footing. After you’ve built the baseboard, you can add vertical boards on either side of the wall. You should place these every six to eight feet.
If you need a retaining wall for your landscaping project, railroad ties can provide the perfect footing. These ties are durable and can last from ten to fifteen years. However, they’ll never last long in areas of water or moisture. Therefore, it is important to level the ground before installing railroad ties as a footing for your retaining wall. A level footing will help ensure that your retaining wall will remain flat and free of settling water.
Once you’ve completed the railroad ties as a footing for your retaining wall, you can finish it by planting sod over them. After that, you can add a decorative border to the wall, wood planks or anything else you want to cover your wall with. Sod is a good option if you have a large lawn. Alternatively, you can simply lay sod over the railroad ties and use it as topsoil.
