Vintage Cobblestone Installation? - Contractor Talk - Professional Construction and Remodeling Forum

What is available for a base for installing Vintage Cobblestones in NC. They vary in depth by as much as an inch. In New England we have a ready and inexpensive supply of Blue Stone Dust.

What would you reccomend that is available and affordable? This is a drive way about 3000 Sq. Ft.

Thanks for your help

New England has nothing on us. We also have Bluestone dust although we call it screenings or quarry fines. Actually I believe it is granite dust but we use it as bedding material typically as a 1" bed on top of ABC gravel. Any quarry or landscape supplier should have it. Where are you located?

Sounds like a pain to lay cobbles with so much variation. Not sure of the most efficient technique.

A saw.

Here in New England most cobbles have that much variance in size. As natural1 said, a bedding layer of stone dust over 8" of road base, each unit set individually with a deadblow.

Yup, just like that. I have just started using polymeric sand also, we'll see how it holds up.

Except, I set my perimeter on end in 4" of hand mixed concrete. The big CT state plow trucks just bounce off of them.

We do the same only in about 12" of crete

I had to remove a 20-liner foot portion of it once. Took me about 6 hours in a tracked cat.

As far as using the poly in the joints, I see no problem with it except for the cost. There is a product that resembles bluestone dust and accommodates joints larger than the typical paver allowances. We use it for dry laid bluestone.

Gatordust, I'll look for that.
