HOW TO: Build a Timber Wall
Рет қаралды 1,077,933
Күн бұрынStep-by-step HOW TO video of building a timber wall with 6" x 6" x 8-foot treated timbers. First tool that will come in handy during construction is a 4-foot level. Footnote: On taller and longer walls you might consider adding a cross-timber on the end of the deadmen (tiebacks running into the ground behind the wall) to create a "T" for added support and strength.

awesome video sir. As an architect, I recommend including a "T" at the end of the deadman so that the deadman has more tearout/bearing and provides more support for the wall. Also, try to offset, uphill, the timbers at least 1/4" per layer so they lean back into the hill. For your purposes here, this should work very well.

1:47 No comment on the black hose. Wasn't in there at 1:35. Oh good, you mention it at 2:35. At 4:46 ... One thing to note is that the bushes are too close to the wall, although a good distance apart. For a guy that carefully measured everything else, I, as a landscaper, got a good laugh out of that. Loved your video! Filled my cart up at Home Depot as you spoke. Thank you. Getting a great price comparison to stone this way. I want to use the buried Ts, stain my wood, and switch to 4ft rebar instead of 2ft.
@bobscaping 3 жыл бұрын
The "black hose" is 4-inch perforated plastic flex pipe. Bushes were intentionally planted close to the wall as that section of lawn is narrow. The 4 ft. rebar is fine if you don't hit rock... or an underground utility line. Have fun!

@@bobscaping You'll lose the stone to the tractor as it cuts the grass and as the grass moves in. (Landscape fabric does not stop grass.) Long-term, it'd be better to add edging, even if only aluminum and not stone. If you really want to cut costs, look for free bricks, and use those to protect some cheap cruddy black rubber edging or the aluminum as I'd suggest. The bricks not only keep the stone in but also act as a rumble strip for the tractor. You can easily spray any grass with a tiny bit of roundup or just let it grow into the bricks like I do; the edging stops most of it.

Also.. Do you use plastic or material around the pipe? and is there a drain coming from between the timbers to allow the water from drain to exit. Liked this video but so much important info missing.
@bobscaping 3 жыл бұрын
Sorry about that Misty, actually getting a job done took priority over making a video in most cases, so things got missed. I don't recall wrapping that perforated pipe with any landscape fabric, but we may have put a layer over top (like a roof) to prevent dirt from percolating downward through the gravel. Some commenters here have made a good case for using pebble-sized river rock instead of the 2b limestone we typically used, since the gaps between stone are slightly larger. In case you missed it, I recently posted a follow-up video of that wall project here: kzfaq.info/get/bejne/fLl2Y8V12KqXip8.html Thanks for watching the Bobscaping channel!

The timber ends were not fastened together. Having each timber spiked into the timber below held them in place, but we made sure to stagger those joints like bricklayers do with brick walls. And of course the timber joints that were sandwiched between timbers, above and below, have extra support.

Two questions. What size do you predrill for the rebar? Also, I'm using this method to install a playset on a slope, kind of looks like what was done for your shed. Basically the bottom 4x6 will be buried all around with a couple inches of paver base. There is a 6 inch difference from high end of slope to low end.. What is the best way to anchor and protect against vertical lift? I want to anchor the playset to the top 4x6's, and I want to make sure during high winds it won't lift the those 4x6 timbers out of the ground. I'll be anchoring the first row with rebar, and was considering playset anchors to anchor to the first row for vertical stability as I'm not sure how well the rebar will hold for vertical lift. The other rows of 4x6's will be fixed with 6 or 10 inch black lag screws.. the playset entire weight is 1000lbs, so I'm sure it will windstand most high wind storms, but I live off a field, and get some pretty strong winds during storms. Thanks!

If the rebar was 5/8-inch we drilled the holes 5/8-inch and used a "mash hammer" (small sledge hammer) to drive them down. I would suggest galvanized spikes and weather resistance lag bolts to help prevent (or slow) corrosion.

Check with your timber supplier for specific recommendations. It's often recommended that CCA treated lumber used for decks and timbers is sealed to help limit leaching and exposure to the treatment chemicals, with arsenic being the most likely to leach. CCA treated timbers were pulled from the market in some countries about 10 years ago. Sealing fully-dried treated timbers might help them a little cosmetically, with cut ends most likely to benefit from sealing for extending longevity.

@octaneaddictions8198 3 жыл бұрын
Yeah, that’s not how you do a “dead man”. It needs another beam parallel to the wall, buried back in behind. With just those beams running perpendicular to the wall, they could potentially pull out. All you have here is the additional friction, holding the wall. If it had a beam fixed parallel, it’d have to pull all that material with it. As said above, your “dead man” need to be “T” shaped. It may be doing just fine, for now. Probably because it’s not getting heavy use. Do this someplace where a car/truck would be driving over it, and you’ll have a failure.

@bobscaping 9 жыл бұрын
We installed deadmen for all except the final two top courses, and it is good to use as many deadmen as possible, especially on taller walls. Some wall builders add crossmembers to the end of their deadmen, creating a 'T' shaped end which gets buried. Not sure we used any landscape fabric between the wall and the shed, but that would not hurt, especially if there is a gap large enough for soil and stone behind the wall to wash out from behind the wall.

phatcat1210 Perhaps you live in a different climate or economy, but this small job was only budgeted for a timber wall. Concrete or masonry would have been too expensive. Most of the walls I have seen "move" in our "freeze-thaw" climate near Pittsburgh, Pa did not have good enough drainage behind them, so we always use a lot of 2b limestone gravel behind a wall to encourage good drainage. These sorts of walls in our area used to be built out of used railroad ties but the laws and hazards with creosote on residential properties changed that picture, plus they are wicked heavy, so we always use "lifetime" pressure treated 6x6 timbers. Most contractors do not "go the extra mile" and use galvanized spikes while constructing these walls, but we paid the extra cost and often drove further looking for them, to ensure better quality and durability.
