Irrigation leak? So what you are telling me it that this wall was not engineered with proper drainage. Hollow core blocks, geo-grid, proper drainage and gravel backfill, proper compacted back fill and you won't have this problem.
Why didn't you bring all this to light BEFORE this disaster happened? You know, if you're so smart and all. Maybe it's because you are one of those that's quick to criticize something you know nothing about. Yeah, I think that's it. If so, you should have stopped all this from ever taking place. Get a life.
It look like a geotextile wall to me, and it is not a total collapse of the wall.the problem was the erosion of materials near the front of the wall,which was of the wrong materials.Graded gravel should have been used instead of sandy materials. Remember the saying,"never build castle on sand?". it may also caused by the wrong construction method of the geotextile near the edge of the wall which should be wraped round the fill materials.

Studies found that it wasn't engineer or contractor error, it was caused by a broken irrigation line that destabilized the backfilled material. Freak accident, nothing more.
I'm a construction management student that has worked landscaping the last few years and I can tell you exactly why that wall failed. It had nothing to do with the contractor that built it or the materials suppliers. This type of wall uses fiber mats to stabilize the soil behind it so that the wall can be built more efficiently and to greater heights. However, the soil behind it needs to be creeping into the wall, otherwise the fiber mats lose tension and fail
The architect and soil testers likely didn't do enough adequate testing and design to ensure that there was the correct soil type, drainage, and earth movement for this type of wall. On a side note, these walls are used everywhere in all climates and are just as strong as solid block walls if designed and built correctly. I've seen standard block walls fail worse than this.
They got the material from Home Depot..and Dan Rather has a source that states the Bush owns stock in Home Depot, therefore it's Bush's fault. Would Dan Rather lie?
I have looked carefully at this video and I keep seeing signs of gopher tunneling. I would be very interested to see if pocket gophers have been tunneling throughout this wall.
As a licensed professional gopher specialist and trapper, I have seen many types of damages, such as these since 1966. Once a gopher tunnels throughout a property and any water gets into it, everything can collapse and slide or wash away.
Honestly, it looks more like a job done by the brick-face and stucco people. Those weren't blocks. They were block faces. Notice how deep they weren't?
Imagine how much worse it could have been if the store had been build right up to that edge? The extra weight could have brought a much bigger piece of the slope down.
The wall might have held better if using larger & thicker (and therefore heavier) stones that were interlocked. I imagine they thought the fabric would devide the fill enough to prevent this from happening but that wall just looks too thin to me. :S
that looks like something from a horror movie. why not just build it on the same level as those houses instead of building an entire fort just for a supermarket?
my only comment would be, from doing this kind of stuff and working in retail also, the store being built isnt owned by the company until all construction is complete, people at lowes dont look at the stabilization reports etc, thats why they hire a company to build it, in the end its the contract companys fault,
this was not an engineering disaster... Engineers are not to be blamed. Its the construction company's that cut corners to save money. And this is what happends....
Not likely due to construction company faults. They had a very explicit design document, which specified materials, slope angle, etc. Where is the lawsuit against the construction company?
I am looking at this from the point of view of a geologist. The angle of repose is 34 degrees. The angle of his slope is considerably more. Were I still teaching at the university, I would use this as a classical example for an urban geology mistake. You are CORRECT, in that many times the construct ion people do cut corners. My feeling remains, however, that pure and simple poor design is involved.
NRCS shows that this is mostly a Balon Loamy Sand, GREAT friction angle, using geosynthetics it would be easy to build a near vertical wall w/o soil nailing.
Chances are the geosynthetics got clogged, either wrong AOS or poor compaction.
The runoff from the parking lot and the dynamic loading it experiences combined with the clogged layers probably built up excessive pore pressure and blew the wall out.
Seriously, if the construction company was not using proper soil not compacting, the design engineer should have caught it, upon inspection. It is ridiculous to think that any municipality would allow a wall this large and not have it inspected by a geotechnical engineer. Mr. Copely is right, it comes back to the engineering. BTW ( kmspike6064) I doubt cement was required in the design of this wall.
well, it seems like the one who built these one though that the mayan piramids have been up for many centuries, these wall should do the same, poor bastard, i think he paid some money under the table to get his license and permits...., welcome to corruption on first world
Hardly a disaster
