Question
I saw a product made to seal gravel paths on a TV news report. IT's supposed to bind the stone but still let water pass thru. They said it has been used at the Biltmore House. Can you help me find some info on this product.   Thanks Ron

Answer
These are two well known brands of the products you are describing.
