CR6, CR8, GAB.....What to use and how much?
Hello all from Clarksburg, MD!
I badly need more parking space and have excavated two separate spots. Each about 20'x20'. So far I've excavated 4-5" by hand (and find myself looking at Bobcat prices) and framed them with 4x4. I plan on filling with almost all base material and compacting a lot with a jumping jack tamper I found on good ole Craigslist...then topping off with a thin layer of 3/4" gravel I already have.
Is 4 inches of base material enough?
Whats the worst that could happen if its not?
Which base material should I use?
I've been quoted:
CR6 at $16 / ton
CR8 at $40 / cubic yard
GAB at $17.50 / ton
Are all these materials similar?...gravel with dust mixed in? I need to knock this project off yesterday, any input is greatly appreciated.
