(at least for me)
already done and paid, let me have it as its only the 3rd wall I've ever done.
feel free to throw out a dollar figure, I sold it at 40' long, 3' high. had enough block to go 3.5 so I did (block come by the full skid and don't want to take them home). carted about 40 yds of dirt out to level the yard and build the wall. drainage, couple plants, topsoil and mulch. also ripped the chimney down and capped it since they are ripping off the second floor and rebuilding. Should be back for the driveway and patio when $$$ permits

ON WITH THE PICS

yea I got a little sketched out when it wouldn't grab and drive out, need some new tires soon. hopefully before winter
AND I DIDNT STAGGER THE CAPS
A few reasons why but i'm fine with it how it is

The wall looks good. The first thing I noticed was the caps. Any pictures of the drainage tile or clean aggregate behind the wall? Looks like a steep slope behind the wall.

nah, it started raining on us and i wanted to beat the traffic home so we just slapped it up. standard 4" black roll of pipe with the sock on it, clean gravel.

Just realized all the pics are taken from the left side. the pipe daylights through the face of the wall by the white fence. we had to slope the grade up to the bottom of the fence so I added a little gravel there for the pipe to dump into. unfortunately this job is 45 minutes away but the neighbor is interested in doing a terraced 2 level wall. might get some pics when I finally head back out there to talk to her. Job was in Queens NY FYI. you can see the neighbors yard in the last pic, any suggestions? never did a terraced wall before.

It looks good, it could be the lighting but it almost looks like u did't mix the pallets and a personal preference I would have stagered the coping and burry the first block

alldayrj
08-20-2012, 10:41 AM
Didn't mix the pallets (4of them) but one was wet/dirty which is probably what you're seeing.
Do I really need to bury more of the first block? I thought a safe bet was 1 inch per foot of wall?
If/When i go back to do the patio, the patio would be running to the base of the wall. should I bury more of the first course then?

No. In this case you do not need to bury more than the first course. For this application you're good with 1" / foot of wall height. If a patio is adjoining the wall - the patio will hold the wall from sliding forward. The purpose of burying block is so the wall doesn't slide.

Pop those caps off and get them staggered.

thanks DVS, kind of disappointed you didnt have more to say haha
as for the access, thats QUEENS BABY. I didnt even meet with these people until they emiled me about 20 pics of the yard and I told them a price range and they OK-ed it. I hate working out there but they pay what I ask. any estimates on a dollar amt?

That means your too cheap!! How does the wall end on the right side as you are looking at it?? Looks like it just abruptly ends... Any Geo fabric?? Also what size is the drainage chimney??

alldayrj
08-20-2012, 08:39 PM
thats what I want to know, what would you guys charge? no geo, about 18" of clean stone behind with 4" pipe.
It ends flat against that concrete wall.

My view is from a smartphone. 2x4 screen.

Last year I made some comments about some steps someone showed on this site, and turned out it wasn't why it appeared
On my little screen.

Well, some loud mouth from out west went off on a tangent telling me I'm full of poop and what a jerk i am and that there is no way my view of the pics was off.....

So when viewing pics via smartphone, I usually don't look them too closely as I'm probably wrong.

Geo is a must on a wall like this..... With out it the soil will bleed into your drainage chimney. Also 18" chimney is pretty weak on a wall of that height.

Ok geo is a must next time. Got it.
Any vague rule for size of drainage next time? I just overdug enough so i had room to work

Dang i have always buried the first course. Now I can save some serious time on my next job!! :cool2: there's always something to learn

We bury the first course too.

Again, just to make myself clear, if there are pavers butting up to the wall - then I may spec the work where the 1st course is not entirely buried as the pavers will keep the block from moving. This is based on the wall being no more than 30" in height.

For the folks that are reading this and that are new to this stuff - it's important to know the reason why block is typically set 1" into the ground for every 12-inches of wall height. And that reason is to keep the wall from sliding forward (down the hill). Note: Sliding and "rotating" are two different things :)

Oh please that not really what it is for. We just do it so we can burn up more block and charge more!!:hammerhead:

Hold on a second, guys. I'm just an amateur builder (4 small walls for various family) but I use this website as a resource to further my knowledge and ensure I'm building structures that will still be standing 15-20 years from now. I have the following concerns with Alldayrj's design and construction. These concerns may not be serious design flaws, but I think you guys, the professionals, owe RJ a more critical review of his work.

Issue 1. No geogrid reinforcement. The wall is 3.5 ft tall. The retained slope behind the wall appears to be or exceed a 3V:1H grade. The slope alone should require geogrid reinforcement. Of all the gravity wall spec's that I've seen from Versalok, Keystone, Allen, Techo, none of them allow a gravity wall above 3ft with a retained slope of that magnitude. I couldn't find the .pdf but I can't imagine that Cornerstone, which I think he used, would approve of this application of their block. DVS,any thoughts?

Issue 2. First course not buried into undisturbed soil. Just piling soil up on the face of the wall and compacting it down does not seem to provide the same level of resistance to kickout as burring into virgin soil. I know DVS said that sometimes the patio can help add reinforcement, but it would seem to me that any movement of the wall would just cause lifting/buckling of the patio surface.

Issue 3. The leveling pad looks to be inadequate. In addition to the concerns mentioned above about not burring the 1st course, the picture does not seem to show a minimum 6 inch deep, well compacted leveling pad. Again I may be mistaken. I think a location of Queens, NY would experience alot of freeze thaw cycles, perhaps some winter melt followed by a hard freeze. My worry is without a deeper, well draining leveling pad the wall may subject to heaving or, in the case of leveling pad degradation, the wall may sink in some area.

Please understand that I'm not attacking RJ. It just seems to me that some of the basic construction practices that have been discussed in great detail on this forum have been disregarded on this project and I would like the professionals to take a moment to discuss. :)

thanks for the thoughtful post, I appreciate it and thats why i posted pics. and to show off my sweet set of tools.

the base is definitely adequate, I didnt show the excavated footing but there is 6" there and its tamped well. also, we took the whole grade of the yard down so its pretty virgin. the dirt we did add back to the face was also tamped.

the slope behind the wall I'm curious to learn more about, as well as terracing walls ( the neighbor wants one)

the block is libertystone 6" mirastone, it was great to work with

All of the force of that slope is pushing on the first course of you wall, hence the importance of burying one full course.

For a terraced wall if you dont set the upper wall back 2x the height of the lower wall, it acts as a single taller wall and would need to be engineered as such.

looks good but my thought is that geo grid is cheap insurance but my other thought is geo fabric between base material and sub soil. It is specs for under patios why not walls? I am also a big fan of using it under base rows. If anyone knows any conflicts with doing that please tell me.
