I have done some searching for some crushed stone coverages but I was unable to find the right answers. I am working on an estimate for about 1500 square feet area that will need to have stone put in. this is a new install. I have a few questions about it. How deep should i spread the stone. Is 4 inches to much or not enough. I am going to put down landscape fabric also. I am planning on using 3/4 stone I found here that 1 yard of mulch @ 3 inches will cover about 100 square feet but I can'f find how much 1 ton of rock will cover. Heres the $$$ question. How do you determine the price for the install. SHould I be charging for 2 guys for 2 hours per ton?? How long will it take to spread a ton of rock?? Any help on this would be appreciated.
