Priming out 200’ of line with bentonite

Using Xtra Gel bentonite to prime out 200' of line off of our Putzmeister 38-5 concrete pump.

Thanks 🙏 for you video 📸

ive done 375 no problem but needed 2 5 gallon buckets of slick mix

[@MuddyfeetConcretePumping]

That’s a tough day at work. Y’all earned your money on this one. Good job on your explanation of the process.

[@canadianconcretepumper1979]

Not a single day goes by that I'm not thankful for our 2" and 2.5" line mixes. Makes these jobs much shall we say, much "less miserable". 😂

Another "pro tip" for bentonite. Use a battery powered drill with spiral paddle, add bentonite to the whirlpool of water in the bucket. Creates a nice, uniform consistency to the batter. No lumpy gravy! All of our line pumps carry this set up and we use it when needed on the booms. I'm thinking of retrofitting an air cuff to my 38Z, a video on air cuff would be great. Thanks Scott, another great Vlog!

[@canadianconcretepumper1979]

Air-cuff is worth its weight in gold! We actually do have the drill setup which you speak of on a couple of the pumps as well as back at our yard, definitely helps to get the bentonite mixed up to consistency lump free in a hurry. Thanks for watching brother 🙏

[@josephrosolowski3575]

I like the drill idea. I use the pressure washer at the shop to mix mine, and I usually carry one bucket premixed on the truck (except in the winter). The drill onboard would be good if something came up unexpectedly

i like the lumps. im somehow convinced they help the prime out@@canadianconcretepumper1979

Nice video I worked at southwest in colorado before it was sold. Southwest is the best. It's crazy how many of the techniques and methods are exactly the same as yalls. I've never been anywhere else that does it just like we do.

[@canadianconcretepumper1979]

I'm guessing you guys must be working with similar materials as to us? We're fortunate around here to have very forgiving concrete which allows us to get away with using 2" and 2.5" hose. I feel for those guys on the east coast and some of the southern states having to use 4" and 5" line.

[@joshrice5964]

@@canadianconcretepumper1979 we use mostly 4 inch line on booms but I carry 3 inch line on my personal pump. I thought SW was affiliated somehow with AJs concrete pumping. Maybe I was mistaken.

How long u like those hoses? We're using 2.5" 10mt for shotcrete and it's hard to handle to say the least.

[@canadianconcretepumper1979]

I find that 25’ lengths for 3.5” and smaller is perfect, 20’ for 3.5” and 4”. Anything over 25’ would be a nightmare to drain by hand (especially for me, being barely 5’9” tall).

[@styzr]

@@canadianconcretepumper1979 I did some calculations and the 10mt hose full of concrete is around 125kg. I need you arms lol

[@canadianconcretepumper1979]

@@styzr nah, just a simple Milwaukee battery powered air compressor and a accompanying blowout cap will suffice 😂😂😂

[@greghughey9738]

I found that shaking the hose as the crunchies pass through will help to alleviate rock packs. 1 5 gallon bucket for every 100 feet of system and walking pace for volume during prime out. Cool to see how other people do it. Stay safe.

[@canadianconcretepumper1979]

Yes, a great technique indeed, pick the hose up and shake it along. What I realized when editing this video was that we had the air-cuff engaged prior to priming (which creates a dry slug at the pinch point of the hose), explains why it got crunchy almost immediately upon priming through the line.

[@dannpriebe]

Nice work. With the big hoses I find the roll as water goes though works best for me and the 3 inch and under I use this roll lengthwise method

[@canadianconcretepumper1979]

Agreed, larger diameter line definitely levels the playing field between the “roll” and twist” methods.

[@johnschmeltz163]

It's warm because of friction not because it's going off

[@canadianconcretepumper1979]

Respectfully disagree. 30+ degrees Celsius concrete batched with non-heated water is a result of hydration and should be treated accordingly.

[@justinharris5834]

I been line pupping for 6 years..... thts the best way to clean out rubber hoses...... we roll 10foot pipes only

[@canadianconcretepumper1979]

I’ve seen in other markets where 10’ lengths of hose are quite common, I always imagined it could be a hassle dealing with all the extra clamps and couplings when dragging the line around.

[@brandonhohaia-portelli3035]

Cement and water mix works a dream just let the water separate from the cement and you’re left with a thick slurry

[@canadianconcretepumper1979]

Agreed, cement and water works great. We use bentonite mostly due to cost as well as ease of use (in our wet climate, carrying sacks of cement on the trucks often ends “badly”) 😂😂😂

Hello sir

[@canadianconcretepumper1979]

Hellooooooo!!!! Thank you for watching the channel brother 🙏

[@stian5815]

When cleaning hoses, I was taught to just continously spray water in and twist it like you said not to do. I was hoping you'd do a 3rd wash and roll to see how clean the water is, cause if it really makes it clean with just those 2 doses, I'm gonna be the most efficient hose cleaner in our workplace lmao

[@canadianconcretepumper1979]

Give it a try, I 100% guarantee they will be clean and free of any concrete. For years I did the twist and roll method and occasionally would miss the odd bit of concrete inside of the hose. Doing the roll mitigates this.

[@canadianconcretepumper1979]

I should say however, when getting into 4” line and larger (something we rarely, if ever do, you’ll need to use a lot more water.

[@stian5815]

@@canadianconcretepumper1979 Just to add onto that, we generally only use 2.5'' and 3'' hoses, works fine regardless by just pumping in like 1-2 gallons per roll? Gonna give this a shot starting monday!

[@tat1ukpable]

Well I never, this used to be my way I used to do a lot of grout pumping with worm driven pumps and bentonate works a treat an it’s cheap as chips

[@tat1ukpable]

It’s also the most disturbing material

[@canadianconcretepumper1979]

Absolutely! Cannot beat the cost/benefit ratio the good old bentonite.

[@Dex01-Z_WingZero]

No rebar???

[@canadianconcretepumper1979]

Aside from detached residential homes (and usually only the higher end ones), sidewalk is poured on grade around here sans the rebar, but using proper compaction/grade prep. Couldn’t tell you the exact reasons as to why (I’m just a dumb pump guy) 😂😂😂

I’ve heard similar claims from others. We wouldn’t make it more than 50’ (on our best day) with just water. It’s highly possible that we’re just no good 😂😂😂
