Is there drainage behind the wall?
Yes, of course. Between the rock and the ledge there is a 12" thick layer of drain rock with a tile drain at the bottom. The tile drain daylights to the outlet under the sidewalk at the street in front of the house.
very nice wall.. I love dry stacked walls. clean lines.
Wow! nice job.
How do you price a job like that? You guys did a great job of fitting and shaping some of those big bastards, I assume a skidsteer put some of them in place.
Yah, the skid steer did the really big ones. But 99% of those were placed by hand. These guys have lots of experience at it. We do quite a lot of these each year. Not usually that long. But we do a lot of them.
As for bidding, you just got to know your production times and costs for materials and expenses. Material costs are easy. 1 ton of basalt wall rock covers approx. 18-22 sq. ft. of wall space. It's the production times that can kill you on a job like that. Fortunately, I've been doing this long enough I know our crews production times quite well. I nailed this one down to within a few hours, fortunately.
You've got some good guys then, Jim. It's tough to keep a decent guy around, the problem is they all think they'll go out and do it on their own. Keep up the great work.
Jim, great work.
Old post, but I figured I'd ask.
Do you use the drain rock to help fill in the gaps on the back face of the wall, or do you completely fill the voids with hearting?
Wow. Way to bring up a really old post!
Anyway, no, we just use small pieces of the natural basalt rock to fill some of the gaps. Small gaps are no problem. Normal for this kind of wall. But if there's a little bigger gap we'll use a very small piece of the basalt rock and pound it in with a mallet.
We've done a lot more of these since I posted this pic 4 years ago. But that one is still the longest dry stack wall we've ever done. It's way longer than the photos show.
Here's a close-up of that same wall where you can see some of the wedges we put in a few gaps.
