Hi! Have any of you ever heard of using glass cullet as a compactable base (instead of sand) under a brick path? I've found a couple of sites that talk about using it in asphalt and cement applications, but have not found anything about using it under a dry application. I have a client who is very interested in using recycled material in her landscape. I'm very interested in learning about this as well. Any thoughts? Would I need something more fine to set bricks onto? These are recycled bricks, so not completely uniform.

Any imput is greatly appreciated. Thanks in advance

I'm not familiar with the term, but am familiar with the concept - one of our local counties got on a temporary kick of using recycled glass in the asphalt. I'm not sure it would work very well as a base material, as the size of the pieces (at least where I saw it had been used) were about a quarter inch square. Not sure you want fines down to dust (not good to breathe), and without fines you'll need something else to help bind up those glass pieces.

If I can remember to do it tomorrow I'll check with our county landfill about how they used the glass - might be of some help. You might try your own county landfill, too.

Thanks for your input! I found a supplier of crushed glass that is measured and sifted just like sand. They are constantly selling the stuff as a base for walkways, etc. I guess they have two sizes (1/4 and 3/8") mixed together to make it compactable and they have sifted out as much of the fine glass dust as possible. Price is comparable to the price of masonry sand (1/4 minus). I'm going to give it a try with this client, but let them know in no uncertain terms that this is an experiment (she seems to like doing these kinds of experiments) and that the work is not guaranteed.

I'll let you know how it goes!

I've used crushed glass on dirt driveways and under flagstone walkway out in the garden. In both cases, the stuff worked great. On the road, it was just graded dirt and clay, and the glass held up surprisingly well for 2 years.
Under the flagstone, the glass is still working well. I installed it in my own garden as an experiment and even now after 4 years, nothing has sunk or shifted.
I got the glass from our city recycler, for free. It acts like sand, the larger glass particals do not cut hands or feet, but the only downfall was for the first couple of weeks, the beer smell and paper labels were coming up.

That's rockin' Penn.

Did you do that?

How does that work?
