Sorry, also cross posted to alt.home.repair
Need to dig out crawl space. Approximately 30' by 50' area. At present it
is about 4" deep. Want to dig down to 42" and lay down a moisture barrier,
put in vents, level house etc. Can't go any deeper due to high water table.
The digging is very easy (sandy loam), but I need clever ideas on how to
drag the dirt out. I have dug down 8 feet along side the house and can
access it with my small tractor/loader. I need ideas of how to
pull/push/drag/roll etc. all of this dirt over to the edge of the house and
drop it down to my waiting tractor. Wife can help a little so maybe roller
conveyers with ropes so I can send her a load and pull my pan back to where
I am digging? Maybe throw the slough on a tarp and winch it out?
Any clever ideas greatly appreciated.
That is what teenage neighborhood boys are for. These days you can also
find neighborhood girls for those kind of jobs. My uncle hired the
neighborhood boys to did out his craw space and make it a basement during
the depression. Some years later when I bought the house, I was often
stopped and told what a great guy my uncle was for helping all those kids
out when they needed a few $$. Of course they were all older them me. My
uncle was a good guy, but a little crazy as well.
In any case, remind them that it is good exercise for (fill in the blank
with the name of the appropriate sport) off season training.
yeah kids dont want to work, I had a truckload of topsoil to move, and
no one would take the job at any price. I had hurt my back, and it
ended up taking a month.
of course if there are mexicans in your area you are all set, illegals
work cheap and hard for cash.........
I hear there are over 300 immigrants in Mass. needing work
or are they in Texas now waiting for deployment?
around the entire perimeter and installed 24" reinforced concrete footings.
Wish I could jack the house up but there is another 1200 square feet
attached that is on slab. Would be very labor intensive to alter the stair
cases and separate the two halves of the house. Easier to dig in situ.
Good to see you're a CE but what do you plan to do with the ~200 yds
~ 3000 tons
That's ~8 "double dumps"
btw I've done the shop vac "moving sandy soil / damp sand" experiment
medium sized shop vac ~10 gallon........ soil removal rate ~ 1gpm
so you've got something on the order of 650 hours of vacuum
time.....not including time to empty & dispose of the dirt.
We're taking about ~100 days of vacuuming (if you can keep at it for 6
hours per day) Even if I'm high by 2x .....still 50 days of
Consider contracting with a vacuum excavator.
Your new footings are 24" wide? How deep?
I hope they go below your intended excavation depth.
cubic yard of loose dirt in about 45 minutes on a continuous basis. Because
of my constraints I am assuming it will take about 2 hours per cubic yard.
That includes running the Kubota to the back acreage for disposal. Maybe I
can lose most of my excess weight?
I'm not disputing that this project is doable.....it is.
But it is a non-trivial undertaking. The fact that you have a Kubota
AND back acreage for disposal will really help out. If you've got
even as little as a half acre you can make this dirt disappear easily
but for me living in an urban / suburban area getting rid of more
than a few yds is a pain.
Check my calcs but 175 yards at 2 hrs per yd ........that's about 2
man months, if you can do it 8 hrs per day.
The final answer isn't going to be 10 work days or 200 work days.
I know of a guy who dug a basement by hand.....weekends & a few hours
here & there after work......took him 3 1/2 years (calender years)
let us know how it works out so we can update our "by hand" dirt
I don't go by "pcf's" or books. I go by real life. In the landscaping
business we load trucks with dirt daily. Somewhat moist pulverized topsoil
is 1 ton per yard. No matter what some pencil pushing geek book writer
I guess we should just close all the libraries, publishing houses,
research activities & pencil manufacturers.
I checked with my field guys (who remove TONS soil) they also think
your number is low for soil to be excavated. :)
Perhaps in situ soil (the stuff the OP's got in his crawlspace) is in
fact denser than the moist "pulverized topsoil".
When you dig it up it loses compaction & density but when you start
with undisturbed soil, its denser.
btw OP doesn't have "moist pulverized topsoil"....he has sandy loam.
Also tell me me how you got 166 yds? I get 176. :)
I have used sleds made out of car hoods and trunk lids. I have also used
hot water tanks cut in half. Two people. One underneath to fill. One
outside to pull it out and empty. The hot water tank would empty by pulling
it sideways with a tractor. Kid could run the tractor and empty. Dig
deeper (basement) and you could use your tractor for digging.
