Pump River Sand Under House

I've gotten 2 quotes so far to pump river sand underneath a 1700 sq ft home to tighten it up from sinkage. Estimated 8-12 loads at 12 yds per load. $6500 was the first quote and $4000 was the 2nd quote. Quotes include labor and materials, etc.

Few questions:

Are these prices decent or should I get a few more?

I think I can get river sand for much cheaper than what they're charging me, and have a fairly good idea of how to do the work. Can I rent the hose(s) and machine myself? Am I biting off more than I can chew trying to do it myself?

Those are (really) good numbers on a per load basis if you need ~10 loads. If they’re providing the labor and the multiple trucks and spraying the sand under your house (with compressed air), I don’t know why someone would attempt this themselves.

To do this yourself, you’ve got to have a fleet of trucks and drivers to constantly reload the pump/conveyor truck, someone to crawl under the house and shoot the sand from the firehouse and somebody to manage reloading & watch the conveyor feeding the hose at the pump truck.

The sand per load at someplace like Wood Resources will cost around ~$40 for 3 cubic yards so the marginal cost for a 12 yard truck shouldn’t be too much more if you can drive right in and they’ll dump it in, but you’ve still got to drive there and back 12 time to your house, while you and friends are pumping. A professional company can do this in a day, DIY could take a few days. I can’t see how you’d spend less than $2,500-$3,000 buying sand, renting a 12 yard dump truck, renting the pump truck and fuel for both trucks, plus 2+ days of your and others’ labor.

I used Bayou Sand Pumping, a sister company of Harold's Plumbing, recently, respond here and I can give you a name and we'll both get a referral discount.

The house is in Metairie.

I feel like $4000 is a great quote, especially given the hassle of doing it myself. Just wanted to get some feedback.

I have access to river sand, a truck, and a driver for about $100 for 12 yds round trip...so I'd spend around $1000 on that part. My concern would be the hose(s) and pump from a functional standpoint...I don't know where to get the equipment and how to use them.

Thanks for the response.

Don’t forget digging a whole bunch of big trenches deep enough for you to get into and get all the way under the house. My cousin did this one summer as a job and he said the digging was always the worst part

Well, depending on how much exposure you have under your house, think about having the drain lines looked at to make sure they are OK and don't need replacing. That is, if it's subsided enough to see the drain lines.

If a plumber has to come out and a crew excavate under a slab to access the lines so they can be changed, you're looking at big $$$$ to have that done. There's a possibility your drain lines may have slight sags in them if the soil subsided enough for them to not be supported.
