Cement Slurry?

[Waterjunky]

Hello all;

I am in need of some type of cement slurry. I need it to flow fairly well down a few holes (several inches in diameter) and to self level to some limited degree. I am not looking for peak strength. Actually I would prefer something that could be broken up if you wanted to get a little violent with it. I have some squirrel holes under slabs that I want to fill in. I keep killing and filling them, then a week or two later new ones dig it back open and move back in. It just needs to be hard enough they cant dig it open again. It also needs to be fluid enough to flow well up into the run and permanently plug it.

Any suggestions?

I am thinking of a lower sack mix of cement and sand. Watery and runny to flow well. Bentonite? Other? Mix ratio? application method suggestion?

Open to ideas but I really need to get this under control.

Thanks

I thought they made that spray foam in a poision version? pack it full of spray foam and cover the hole good.

This or equivalent like cement all non shrink

 

[evantwheeler]

Adding a small amount of plasticizer into your slurry will keep water ratio lower, reduce shrinkage and keep the cement particles from falling out of suspension. I would use a microfine or non-shrink cement as recommended above. Concrete mixing is a very fine science, small changes in ratios can make HUGE changes in the mix and performance.

I think he's looking to fill in gopher holes, not grouting base plates....

2sk slurry with some added bentonite to help flow would work just fine,

 

[Waterjunky]

Sguirrel holes but same concept. I am liking what I am reading on this.

I need it to start out fairly runny and then set up

This works pretty good. Little pricey though.

Why complicate things?

It's pourable. That's why I recommended it. Non-shrink grout is often used to provide fill around and under machine, structural, and pump bases after they're leveled. The non-shrink qualities provide permanent support. It can be obtained in strengths up to 5,000 PSI.

Some Sika NSG products can run over a hundred bucks per bag depending on the specific application. The Lowe's product I linked is twenty bucks, and therefore a good choice for squirrel holes.

@evantwheeler made a good suggestion.

PS.
For gophers i use these and a shop vac on blower mode. Stick a few down at a time and looks like a civil war reenactment.

 

[hallett21]

Not to be that guy. But why wouldn’t the squirrels just dig new holes deeper?

Build a big wall and I’ll just build a bigger ladder .

"I am not looking for peak strength. Actually I would prefer something that could be broken up if you wanted to get a little violent with it."

5,000 PSI probably isn't exactly what he's looking for, but they're not my squirrels.....

5,000 PSI probally isny exactly what hes looking for, but they're not my squirrels.....

I didn't tell him to use 5,000 PSI grout. I explained what it is used for and that it is available in that range of strength.

Like most of the useless nonsense I spout about stuff, I know these details because I've grouted over at least a hundred pump and structural bases. Is that a big deal or does it make me important? Nope. I just like to share.

Got it, perhaps someday we can exchange notes on how many items we've grouted in the last 44 years, at least for me,

Thanks!

 

[srttruck]

I'll get flamed but here we go, 1 shovel cement, 15 shovels sand, mix with water till the consistency of a liquid mix you think you can pour easily.

Fortunately those days are behind me. I don't think I could bend over long enough to do it either.

I have people for that now days!!!

 

[lbhsbz]

About a pint of Gasoline down each hole…borrow some manhole covers to cover the holes…give it 15 minutes on a warm day and drop a match.

That should solve yore problem

 

[JUSTWANNARACE]

Concrete self leveling mix for floors!

 

[LGETT]

There is a product called Quick Rock
Comes as a powder form, mix and pours like liquid, hardens quickly also.

Another option would be plaster peris

Someone with a camera rolling should always be around when gasoline is used in pest control activities.

Those dogs didn't shit right for two weeks.

 

[bradscott48]

What you’re looking for is called flowable fill. Mix yourself a 5:1 ratio of lime or gypsum to Portland cement. Add 50 lbs of sand and a lot of water. It’ll make 25-40 psi.

I buy them by the case......
This has been my historical "go to". The issue is that new ones dig open the burrow and re-infest. If I can seal the burrow, its much more difficult to move back in.

This is a lot more work and much slower than moving a little soft dirt and opening up the colony again.

I can never get rid of all of them as there is habitat I cannot control that provides a breeding ground nearby. If i can make their lives more difficult, they will be less likely and slower to move in.

I am also looking at upping my game with one of these. Not cheap but I think I have spend 2/3's that on gassers (no joke)......

He also did a good job of aerating the lawn. It'll green right up.

A older diesel is more effective.

I tied some dryer ducting hooked up to an old edger. Didn’t do anything but burn my hand. Let me know how it works. Neighbor at the end of the block ha a gopher amnesty program. They make it down once a year. My job is to stop it before it hits my 90yr old neighbors house. She’ll blame me for any damage.

 

[Orange Juice]

A friend had same issue with small ground squirrels. He used wire screen and buried it around the slab about 8 inches deep.

I have two small dogs, and they keep everything away in the back yard.

 

[Sherpa]

use the smaller 5" box traps. I've trapped probably over 200 of the little bastards in my backyard. we live near a park...

The squirrels will dig new burrows, and you'll be pouring again soon if you don't handle the squirrel issue. IF you've got open land around you, you are fighting an uphill battle, but with a little effort you can put a dent in the population to a point where you can easily keep up with any damage they cause. Filling squirrel burrows with slurry seems labor intensive to me.

If you don't have small animals around that will eat the carcasses, get some Ramik Green, make some PVC feeders, and keep them stocked. They have to eat the bait for three days in a row before it starts to work. If you break the cycle, you have to start over. Make sure all openings into any structure are rodent tight, or they'll crawl in and die and then you have to deal with the smell. Plan to keep these feeders full for the long term.

Smoke the open holes with any OTC smoke bombs and seal. Smoke any new holes you see immediately.

Buy a couple of live traps for squirrels. Buy a trash can they will fit in. Fill trash can with water. Set live traps in quiet places that see little to no traffic.

Next, get two high-powered pellet rifles with scopes or good sights. Put them in places where you can get to them without having to open outside doors or even walk outside. Keep them in different locations, and have some fun shooting from your kitchen island or table through a cracked slider or from the back of your garage through open doors.

Finally, Fence in the area, and get some yappers that will patrol and make it a dangerous place for them to come to.

Have fun. Good Luck

IMO After 15 mins you’d be lucky to get it to ignite…

LMAO! Good one brother.

I didn’t read every response however I have the same issue at our rentals told they were ground squirrels that are digging and creating havoc. I hired a guy to come and gas them since the first guy we hired used pellets to no avail. This guy has a gas powered unit that the exhaust is hooked up to a hose and he places the hose in the hole and runs it also adds a smoke to see where it pops up. They he buries the holes so they die in there seemed to work for us after one treatment. Was only like 200.00 for him to come out and handle it. I would find someone in your area to do this as those holes went all over you may go broke adding a cement slurry I wanted to use foam but heard they will chew thru it.

Good luck

I drained a 13,000 gallon pool into a gopher hole when I lived in CHino, CA and never filled it up. Those little bastards can dig.

 

[Waterjunky]

The holes I am looking to fill are strictly the ones under slabs and foundations. There is a corner of my mind worried that I will be driving my forklift or something and crack out a spot on the floor if it continues. The amount of dirt they have removed is shocking.......

 

[Waterjunky]

My wife thinks it is hilarious when I am shooting them with a 22. I did it one Sunday morning buck naked. I think that image of just how redneck I can be is forever burnt into her memory.

 

[Mandelon]

The Squirrelinator trap works well. My wife relocated four of those fuzzy guys in the past couple of weeks. Probably not work on gophers.
