Frequently Asked Questions

Q: Is there a minimum required to purchase?


A: Since DeFeo Materials is a Bulk distributer of stone, we only ship truckloads of materials. Our minimum required order is 23 tons.  We can provide you however with the name, address and phone number of your local landscape yard that carries our discount stone products!

Q: Can you keep up with our delivery demands


A: DeFeo Materials owns a fleet of company owned tractor trailers. In addition, other trucking companies are called in for additional trucking power.  We have over 50 trucks at our disposal at all times.  Our reputation for our word being good has allowed us to grow to one of the largest wholesale decorative stone suppliers on the east coast. 

Q: Stone or mulch?


A: Mulch is a great, temporary landscaping solution.  Decorative stone however is a permeant fix to any landscape! Stone only has to be purchased and applied once, while mulch has to be spread at least once if not twice a year to look sufficient.  Therefore stone is a long term, low maintenance option for every landscape usage!

A: Our ravishing colors, including blacks, blues, pinks and whites are absolutely eye catching.  The round shape of our rock quarried in New England is another impressive benefit to our stone.

A: Not only do we have large stockpiles at our quarries, we also screen material daily.  Our stone reserves are estimated to contain an additional 15 million tons of stone!

Q: Where does river rock come from?


A: Many believe that river rock is directly produced from rivers or lakes.  However, round stone comes from deposits left behind, beside rivers from glaciers.  These glaciers moved the river bottoms and deposited the minerals and stone nearby.

Q: What is decorative stone used for?

Q: How do I know how much stone I need for a job?


A: Looking to renovate your home or business, but are unsure of where to start? The good news is it is fairly simple to calculate how much product you will need for a job. You will want to first measure your area to get your cubic yards. From there you are able to assess how many tons or pallets you may need for the given area!

Q: How many tons are in a yard?


A: in general, 1.33 tons = 1 yard of stone. However this can depend on the exact size and the classification of the stone. For example, granite is a very heavy stone and slate is a very light rock. The composition and density has a huge effect on the weight to volume ratio. 

Q: How many cubic feet are in a cubic yard?


A: there are 27 cubic feet in one cubic yard. Cubic yards are used for measuring the quantity of stone you will need to fill a desired area with the selected stone, mulch or material of choice.
