    I know this is in the wrong forum but it will get seen here faster. I have a spot at my house i want to make into a parking spot for my work truck. I have a small driveway and have a car a work truck and a SUV to park. I can only fit the wifes car and my SUV now. how should i go about making this drive? Lay plastic over the weeds and grass then the gravel or kill off all weeds and grass and lay gravel. I have 200 sq.ft to do. And about how many yard of gravel will i need to do at 2 inches. I was also wodering about making a border so the gravel wont spread

    If I"m figuring right 1.5 cu. yds. will do 12x20 area 2" thick or slightly thicker,
    make it 2yds for variable depths, dump it right over the weeds & grass anything comes thru just spray with round up after. I would think if you wanted to keep it contained run a row of retaining blocks, that would probly look pretty nice. :waving:
    some reason 2yds just don't sound right to me but I can't figure out why.

    Remove the topsoil off the area, add 411 limestone which are fines and dust and water then tamp, this will turn the 411s into almost a concrete base. Then top with either #57s or the smaller #8, the 57s are 3/4" and bond toghter better than 8s. You will need at least 5 tons of the 411 to form the base maybe more if you have alot of topsoil to remove. Removal of the top soil will prevent the stone from sinking out of sight

    to find out how many yards do Length x Width x Heighth, in feet. so thats cubed. Then divide by 9 and thats how many yards you need.

    for instance, if you had 12x12, and wanted it 4" deep. you do 12'x12'x4/12 so that is 48ft cubed. then I divide by 9 and thats 5 1/3 yards you need.

    hope this helps you figure out how to do the math to figure out how many yards you need.

    ya so my figure of 1.5 to 2 yds for a 12 x 20 x 2" area is correct. right?
    some reason that amount just seems low to me, but everytime i refigure it I get the same answer. :D

    well lets see. 12'x20'x2/12 (2/12 because 2" is 2/12 in feet) is 40, then divide that by 9 and you get 4.44. So from my calculations thats 4.44 yards you need, I'd order 4.5 yards.

    I think you did 12x20x2/12 then you divide by 27... but you only divide by 27 when your doing inches, and sense you were doing feet, you divide by 9.

    Now that I think about it... Im wrong, your right. You do divide by 27 at the end, I dont know why I thought divide by 9.

    or you can do 12x20x2 then divide by 324
     
  9. You absolutely want to remove the topsoil, you might also want to put down some stabilization fabric on top of the subsoil before you put down your base. That base of small gravel and fines is what we call item 4, every area seems to call it by their own local name but I've seen it referenced to on NYS specs so your gravel producers in western NY should be familiar with it.

    actually. I was talking to my bro, and he said I was right at first. because sense its a cubic yard, I guess you do divide by 9 at the end.

    Now I got alotta people thinking about this prolly. LOL...

    but in my oppinion, I think its 12x20x1/6 divide by 9.... which is 4.5 cubic yards. thats what I think personally. but I may be wrong.
