NASTY boom + 300 feet of line job.

Pumping concrete through 300 feet of hose from a Putzmeister 38-5 boom pump.
This is at the new Burnaby Hospital, which is currently under construction in Burnaby, British Columbia, Canada

Been pumping for 18 years and that's exactly how we do our linepours .. I'm fortunate enough to work for a ready mix/ pump company so I get the same consistent quality of crete which makes linepours a lot less stressful only difference is we use 4inch line

[@canadianconcretepumper1979]

It’s so true. With our residential work we use the same supplier and mix designs 90% of the time. It really does take so much of the stress out of doing these long line pours. Kudos to you guys for lugging that 4” system around. Unless we’re pushing big volume on a commercial pour, 3.5” hose is about the biggest we get into running at the discharge end of our line pours.

[@johnfarr3128]

We now have a 18v Milwaukee compressor and I’ve made a 5’ air hose and it’s a real life changer even for 4” gear

[@canadianconcretepumper1979]

Honestly John, it is dollar for dollar one of the best pieces we have invested in. Must be slow as molasses with that 4” system though, no? We had a project in which we were blowing out 300+ feet of 3” system on the daily. We wound up piggybacking the compressor to an auxiliary 10 gallon air tank. Having that extra capacity really helped to get the initial push started when blowing out the lines.

[@johnfarr3128]

@@canadianconcretepumper1979 I pushed 200’ back a few weeks ago it wasn’t the fastest but I feel like with the small compressor it’s safer like you said it takes much longer for it to get out of hand also it still beats running all the air hose out and hoping the last guy filled the compressor ( we use ours on are vsp 70 so no air onboard )

[@victariondrownedmemory9886]

you always have the best plans when it comes to nailing these difficult nightmare jobs my dude, when i saw how much hose you had out and all the obstacles in the way i chuckled. your experience shows, if for some reason i ever move to BC id gladly work under you and absorb as much pumping knowledge as i could. Right now my season is just starting here in Calgary, been kicking ass with my boss's Reed, mainly doing basements but private jobs will be starting up soon for sure. my setup is really simple though eh i dont use a compressor or a water tank so drain everything manually or pump the hopper down on site, only time that sucks is on a private job with no washout spot, i call hopper to driver early then pump out as much as i can, drain hoses into the job and then use square buckets underneath pump and hand bomb anything remaining. sounds alot harder then it is, last season i was doing 2 basements a day then usually 2-3 private jobs after that so i was fucking jacked haha. ive told my boss to grab us a pallet of bentonite after watching you guys prime so much line with it and having no hiccups, im planning on wearing a go pro soon and uploading footage of our pours ! keep kicking ass my guy and representing Canada booya

[@canadianconcretepumper1979]

That’s what I love about the little line-pumps, we can literally wash the things out into 5 gallon pails if need be. Have you seen the plastic tubs which we carry on our line-pumps? (credit to Jeff over at Muddy Feet Concrete Pumping for putting me onto those). They are super handy for washing out into. Highly recommend.

Great workers Bro, in a bad job 👏👏👏 saluti dall’Italia 🇮🇹 (I’m an operator on a concrete pump CIFA Metro 28 Italian brand)

[@DeruginizCLS]

I’m assuming this would be considered a “specialty job” and you charge much more than the normal rate? With all that line and multiple operators and all…

[@canadianconcretepumper1979]

Yes sir. Each extra guy is billed at operator rate from yard-yard. There is also a delivery fee for the line. This is all on top of the regular rate for the pump and operator, of course. With the cost of hoses these days, we almost need to look into a per ft. rental charge for the line as well. I ordered of four new 25’ long 2.5” hoses yesterday. Just about fell over when I heard the price.

[@DeruginizCLS]

@@canadianconcretepumper1979 Exactly. We actually started charging about $1.75 per foot after 150ft of line. That’s with our 2.5 inch line on our VSP 70.

[@sirmister4411]

Your pressure is also relative to cylinder size to final hose size and cylinder speed x to volume of hose size at a piston speed ratio minus concrete powder to sand ratio and standard crushed stone compared to round stone £ slump scale Got it. Good

[@canadianconcretepumper1979]

Absolutely. It is for that very reason we prefer using our boom pumps with 9” material cylinder pumping kits for these types of jobs. The 10” and larger kits just don’t cope nearly as well on these long pushes. 👍🏼👍🏼👍🏼

[@jimmartin8024]

Just watched your video on water washing...is it a troll video? I'm stumped by the fact that you don't know how to water wash...I've been watching your content for a year or so and you seem very knowledgeable about pumping concrete.This is not meant to be disrespectful.

[@canadianconcretepumper1979]

I wish it were 😂😂😂 But seriously, water-washing in our area is completely unheard of, quite literally no one does it up here.

[@newrealm9187]

I’ve noticed most of your starts are in sunlight, do you not do many early pours? But yes this is a nightmare job

[@canadianconcretepumper1979]

Due to noise bylaws and required “special permitting” it’s very rare that we are ever on site with the pump prior to 7:00AM. Aside from bridge decks and/or infrastructure work, legit night pours are mostly unheard of here. With how bad traffic has become in the city here, it does seem like pouring during the off-hours would be far more efficient at times.

[@newrealm9187]

Scott, I got three questions if you don’t mind where was that , what was it a hospital and how many guys did you have on-site. Thanks👍

[@canadianconcretepumper1979]

So this is at the new expansion to the Burnaby Hospital (the end screen of this video had a link to a previous raft slab footing which we poured here in the earlier stages of the project). We had the boom pump operator stationed down at the hopper and 3 guys up top to setup and manage the line (4, if you include the mostly camera man…. me) 😂😂😂

[@TheConcreteman006]

Covered a bunch of bases! Had to have a bunch of retard/set delay in the mud. Without a solod gameplan and execution, all kinds of bad things can happen. Well done guys.

[@canadianconcretepumper1979]

Thank you brother, we much appreciate the kinds words. I had debated to request a dose of retarder in each of the loads, but in our market, these higher strength mixes (6000 psi here) actually tend to set slower as the batch-plantain refrain from using re-claimed water in them. I was definitely a little concerned the morning of when it wound up being our warmest day of the year this far. Mix held on really nicely though. Timing for the trucks was near perfect as such that they weren’t wait on a round too long before getting onto the pump. All in all, a pretty good day considering how the potential for adversity with pours like this.

[@BenBNC]

So if you plug at like 275' a few hits in reverse probably isnt going to relieve that pressure. Lets say you plugged, and the clamps are still super tight and you know theres pressure. Whats the protocol? Honest feeling is that youre probably super unlikely to plug if you have all that grout ahead of it with a juicy mix behind it.

[@BenBNC]

and wait wait.... you primed what, 50-75 feet of hoses at the end there with water?? risky business right there. I would have rock packed halfway thru the first hose

[@yotaforlife8408]

I always put 3 small packs of slick pack in the primer port and fill it with water the send a good hopper full of wet grout behind it followed by the crete ofcourse... I never have issues at all and I only get 1 helper on my jobs so less problems less back pain lol

We actually don’t see much/any lightweight aggregate in our area (thankfully, as I’ve heard it can be a real bear to pump).

[@TheConcreteman006]

Glad you added the guy tapping on the 3-2.5 reducer. Lots of squeeze going on there with all the rubber on after that. Also, showing what happens when you try to increase speed...more pressure and not much volume. My simple philosophy is you can only shove so much shit thru a straw...no matter how hard you push. Your setup was close to as small as possible, made every one's life easier (Lil rough on the pump and system). I have midnight pours all week Beverly hills, all 4" thru tremie pipe, maybe I learn how to film...

[@canadianconcretepumper1979]

@@TheConcreteman006 It would have been so much easier on the pump here if we’d run all 3” line. We elected to go with 2.5” as it’s much less prone to kinking under its own weight when being hung vertical (between the multiple levels of pan-deck as well as crane infills). The other big challenge here was working around/between the multiple other trades. Would have been nice to get in here a day early and lay everything out ahead of time, but it would have been in the way of everything else going on. The 2.5” line was nice in terms of quick/efficient setup, moving, and takedown, but most definitely had the pump WORKING!!! If I hadn’t been out pumping this very same mix through a couple hundred feet of 2.5” just a week or two prior to this pour, I likely would not have had the confidence to run so much 2.5” rubber here on pour day. What doesn’t kill us makes us stronger… (except maybe not in the pump’s case)😁😁😁

I hate to say it, but we had a guy forget to check the orientation of the diversion valve on a 600 cubic meter high rise pour.

So we normally don’t see man-sand in our area here. Over the past couple of years however we have seen variations in natural sand suppliers. To me, this stuff appeared to be using a more coarse grade of sand as compared to what we are accustomed to seeing. With how wet it was going into the pump and how “clumpy” it was exiting the hose, it was behaving somewhat similar to manufactured sand.
