A hard wall to build?
Here's one for all you wall builders.
I have to build a retaining wall that will hold a portable MRI trailer. The wall will be 56' long, then changes direction 45 degrees for another 28', height varies from 2' to 4.5'.
The trailer weighs 60,000 lbs plus, I need to support the truck that will move it, figure 80,000 lbs. Now that you have the easy part, they want plastic Geo-block filled with dirt so we can seed it. Oh did I forget to mention the ADA ramp that is needed so they can wheel patents up it?

plastic Geo-Block - is that those sonic bonded sheets of plastic to make pockets?
That whole project is engineered, isn't it?
I've been propositioned with the unusual (for me) situation of designing a pond and landscape layout for a developer for 1 acre, high-end resi lots.

Paul,
Are you using tactile pavers for the ramps? Is the block spec like Unilock's old school alpstein (sp)?
Good luck
Rex

If this was designed by an engineer then follow the spec's and go for it. There is really no magic involved in the building of a project like this and you easily have the skills for this. If they are asking you to design and build, hire an engineer or forget it. There seems to be the chance of a lot of liability here. It also sounds like a good project that you don't want to turn your nose up to.

It's been engineered, this site has 3 different soil types. So we picked the worst soil type to deal with. The wall will be Siena Stone a bit over 300 fc ft. The easy part about this, all back fill will be stone, taking out 200 cu yds of dirt to install it.

Sienna Stone for this will be quite nice, and a quick install. Any geo-grid engineered in it? What happened with theGeo block, and what the heck is it? Sounds like a good project. DO you have a clamp for the Siennas or do you just use a skid and muscle them in?

Heres the web site for Geoblock http://www.sspco.org/geoblock.html
Yes there will be geogrid. 2 layers about 8' long each. Unilock supplies us with the clamp, for 300 fc ft we will need it for a day. |

Looks like one of the products from Presto: http://www.prestogeo.com/
The geoweb is made locally - the Geoweb is actually sonic bonded - no glue, no heat. (Well, there is heat, but it's because of the sound vibrations). It's made right here in WI.  |

all I know is I just had a tandem back down a driveway on a lake today that was supported by a 12 ft tall RR tie wall that was about 10 degrees out at the top.
If that wall can work for this long.......I'm sure yours will be fine!
