Siena Stone Wall

Hey folks,

I hope everyone is good!!

I just spent a little while reading through some of the Pisa and Siena Stone wall posts and learned a fair bit.

The one thing I am still stuck on is probably the most basic so I thought I'd ask it here.

My supplier gave me prices for the following "pieces":

Standard 500 Unit, 333 Unit, 500 Unit and 925 Unit.

What I am not clear on is which I use for the base and which I use for successive courses. Or, is only one unit used for base and courses and the size depends on how large the wall is to be?

The wall I am quoting on is going to be approx. 150ft long and approx. 6-8" high. My assumption is I will have two courses below grade and two or three above grade.

In looking at some of the info on the RisiStone site (see link below) it looks like the standard unit can be used for base course and the courses above.


http://www.risistone.com/products/ma...lls/sienastone

So I think what I need to do is divide the width of the standard unit into my overall length of 150 feet, multiply by the number of courses and then multiply that by the cost of each standard unit.

150 feet divided by 48 in. (width of standard unit)
= 37.5 units per course

4 courses x 37.5 units per course = 150 units

Coping would also be 37.5 units

Then I need to account for:

- excavating trench
- installing and compacting base
- adding drainage tile (with sock) in behind wall
- installing geotextile (will I need it for only 4 courses)?
- backfilling with gravel
- actual placement of blocks using clamp
- finish work: adding soil and sod

Am I on the right track?

I am hoping Paul and SLC and some of the other "gurus" that I saw posting in the other threads will weigh in on it. Some dated back to 2002 so hopefully they're still around.

THANKS ALL!

no they aren't any more. They go on groundtradesxchange(dot)com.
Any way: sienna stone
unilock can send in an engineer to help you figure out how many of the 925's you need for your base rows. Then how many 500's you need and so on. I'm assuming you meant 6-8ft, so The engineer can tell you if geo grid is required.

If i'm reading correctly you are only wanting to do 4 rows high? That's 30in with sienna stone. That stone is way over kill and pricey too! Pisa 2 would be a better option.

Siena

Thanks amish,

I did actually mean 6-8" and not 6-8ft.

The engineered plan shows a wall made by Nava Stone called "Grande" but I am not finding anything about it on the net and apparently the supplier is quite far from the site. That's why I've decided to use Unilock instead. The contractor doing the grading and catch basins said he uses Siena stone alot and he is going to price the wall also.

The T/W (top of wall) and B/W (bottom of wall) grade points on the plan only differ by .15m which is 15cm or 6".

The cut-aways I've seen seem to show the same sized (width) brick on the bottom course and the ones above.

GL
