Retaining walls are built to create level planting areas or to increase usable yard space. One of the most common failings I see in the building of retaining walls is that the builders seem to fall into the trap of building all of them pretty much the same way with posts at about four foot spacing (or six), when the loads may vary from very light to extremely heavy. Stone is a relatively cheap building material, if you have an abundant source of natural stone on your property.
Don’t make the mistake that, if you cover the face of a cut or fill with a strong material, it will be an effective retaining wall. In this video, This Old House landscape contractor Roger Cook shows how to construct a wood-timber retaining wall to create a play area. For this reason, the preferred material for food garden applications is the foundation grade redwood or cedar, which is a more expensive, but healthier choice. These can be used to brace up your new retaining wall until you have the chance to get all of your fasteners in place.
If the paving already exists and you want the wall to be flush with it, be careful not to disturb the foundation of the paving when preparing the wall base. A dead man runs perpendicular to the wall and back into the ground you are retaining. So your drainage scheme is designed to take water away from the wall quickly, while keeping it away from the wall itself (so it can’t push on it).
When the area is back filled this timber will act as an anchor to hold the wall in place and ensurer your timber retaining wall can withstand time and rough conditions. I have a long railroad tie retaining wall that needs replacing (literally falling apart). Cut the slope back 12 to 15 inches from the rear of the trench to leave room for gravel backfill and a drainpipe – a must for retaining walls.
There are a wide variety of timber that each have advantages and disadvantages when used as part of a retaining wall. Wooden retaining walls supporting a level backfill can be constructed of 2 x 12 inch pressure treated lumber, 3 boards maximum in height, supported with pressure treated posts every 3 feet buried in concrete to a depth equal to the exposed height of the wall. Hammer wooden stakes in the ground at each end of the trench, and stretch a string between them even with the top of the first stone.
I have to construct RCC retaining wall of hight about 24 meters for retaining eEarth in lateral direction. This technique offsets the center of gravity of the wall making it harder to tip over. Maybe you have just newly finished excavating 80 feet of trenching 3′ deep to install a footing for your retaining wall. Typically made of landscape timbers, a wood retaining wall is affordable and relatively easy to build. The best thing to use is a long wood auger bit as opposed to one of those drill bit extender things.
If you are using a heavy duty drill with extensions, avoid applying undue pressure as it can cause the bit to snap. This can be built using a Timber Shutter, which basically consists of a wooden box into which you pour concrete and then allow 48 hours for it to set. There are many different varieties of materials available for building retaining walls. Coat (dip or paint) the ends, especially freshly cut ones, with wood preservative to prevent rot.
Don’t ignore the outdoors – It is very easy to get consumed by the layout of your kitchen and other areas inside the walls of your floor plan; but one of the common traps is not fully considering what is happening outside the building. We have enough experience and seen enough timber walls, that we can help you decide on the type of wood that fits your decor, your wall’s purpose, and your wallet. Tie all of the timber together using 10” spikes (if your wall is made of 6×6 timbers) or a spike long enough to go through both.
All that is left now is to extend the gravel driveway up around the wall to the door of the shop. These nasty chemicals make the difference between a few years and several decades of life span for wood that’s in contact with the ground. Enhance the look of your home with a concrete retaining wall: simply follow the steps described here below, and build it yourself. Unless you are using really heavy materials or a professional retaining wall design, do not use this design to build a wall that is any more than 16″ or two feet tall.
Timber retaining wall construction projects is something do-it-yourselfers can tackle if they have the right tools and time. Having fixed the sleepers in place and set the concrete, you can also connect the backs of the sleepers together, with lengths of wood, metal strips or wire. More post per length is one of the easiest ways to make a stronger retaining wall. Set the first post on the sand footing and adjust the stanchion until it’s plumb and roughly square to the direction of the wall face.
There are many materials and several methods you can choose from to build retaining walls that will meet your requirements, and can also be built within your budget. Builders know this as frost heave, and water-works employees know that this pressure cracks water mains underground. This will provide bottom drainage for the wall, allowing the water to drain away through the gravel instead of pushing the railroad ties out or eroding the dirt away from the wall. In the right setting, a timber retaining wall blends into a landscape more naturally than any other material.
If you need a truckload of dirt delivered, have it dumped on the uphill side of the wall, if possible, but not so close that the truck threatens the wall. We can construct your retaining wall from a variety of materials to give it any look you can imagine. Divide the total wall length of each tier by 4 and add 1 to get the total number you need to build. If you inquire, you can find out where the wood was grown and how it was harvested.
Building a long-lasting retaining wall is vastly more complicated than simply piling up blocks and shoveling dirt. The Wall – for a cast in place (concrete) retaining wall with a vertical face, installed on no more than a 33 degree slope with a level embankment, at 6′ high (including excavation and backfill) the cost will be $12,800. ANY MORE DEPTH MIGHT NEED TO BE TIED INTO A BUTTRES,OR ON AN INSIDE WALL WOULD BE A SMALLER PILASTER. The length of the header depends on its placement in the wall, the height of the wall, the soil type, soil and surface water movement, and any surcharge at the top of the wall.
I have built retaining walls out of 6×6’s with a dead man every 8′ on every other coarse of 6×6’s it has worked well. After digging your trench, lower the Sleepers one by one into the trench ramming them together. If you choose to use pressure-treated wood and don’t mind the green roller-marked appearance, be sure to use suitable metal hardware since this PT wood contains a great deal of copper (much more than in the past since the removal of the arsenic) and is highly corrosive to ferrous metals such as steel and iron. Anchor them to the wood the way you did and extend into the backfill about 5 feet.
I personally think using the retaining boards vertically will give you a stronger wall because of the specifics of that particular design. A retaining wall is built to help stem the erosion of property, to protect a yard from rising water, or to help create a flat space on a sloped piece of land. To maximize your timber wall longevity, the contractor must pay close attention to water, where it gathers and pools both on top and behind the wall. A 4-foot-high, 15-foot-long wall could be holding back as much as 20 tons of saturated soil.
If your wall is designed with corners, the corner blocks must overlap at the joints to tie the two legs together. Since any water trapped behind the wall is extremely heavy, all retaining walls should be backfilled with coarse gravel that drains quickly. A contractor without ethics may recommend and an unnecessarily expensive retaining wall. When the wall is increased to 8′ in height the cost will average at $13,700, and when the height is bumped up to 10′ the cost increases to $19,900.
Wear approved goggles, safety glasses and a face shield when cutting creosoted wood or when sawing or breaking stone and brick. Very well described, but I did have one question.. it looks like you recessed each level as you moved up the stack of ties. Although this shifting may require an occasional readjustment to the wall, the trade-off is the relative ease and low cost of building. A retaining wall is just like any other construction project, except on a smaller scale. You’ll end up with a hill of hand-shoveled dirt that traps the gravel against the wall.
Garden walls and fences less than 6 feet high are exempt from permit requirements; however, zoning approval may be needed in some areas of the city. As you know, ties are 6 x 8 feet x 8 inches (more or less) chunks of pine, redwood, or oak treated with wood preservatives (usually creosote but sometimes also pentachlorophenol). I once rented a house in a very hilly area where a previous owner had a railroad tie retaining wall.
