Re: Power Screeds


I have used a lindy vibra strike form many years. If you have a couple of good rakers you can lay alot of mud down fast. I love the way the cream comes to the top and the rocks go down. It make it alot easier for finishing IMHO

Re: Power Screeds


Ive used Vibra Strike and Advanced Concrete Tools Screed and the Advanced is by far the best. The problem with channel and "partial" triangle boards like Vibra strikes, is that they can be to forgiving and can cause the screed to ride over high spots, the advance screed has a true triangle board and is NOT forgiving at all. Use at least a 10' board but would recommend a 12'. Do not get a weedeater type operation, will kill your back, the 2 handle or T handles are a lot better.

Re: Power Screeds


Power screeds in general are a beautiful concept, but don't be fooled. They are dangerous without a an experienced operator. I have floated behind these screeds going on 15 years. Sometimes it is beautiful. I have also had some of my worst nightmares behind someone who doesn't know what he is doing. Vibration is a good thing. When concrete is consolidated with humps and dips, it is twice as hard to repair them with your bull float. Vibration also means that if the roll in front of the screed varies too much it will cause bubbling or settling behind the screed. Consistency and a smooth stroke is very important.

Re: Power Screeds


I agree with bobcatnelson. We like to have the option to vibe or not vibe as needed. We use a vibe screed and it seems to be the most usable tool we have. We just ordered a two sets of apearms to attach to the screed board so we can stand and screed. We do mosly home foundations, sidewalks and driveways. We just switched from wood 2-by-4 to metal.

Re: Power Screeds


I have rented quite a few screeds until I made my first screed purchase. About 2 years ago I bought a Packer Brothers power screed and it is very easy to use. I bought their lighter weight model for wet screeding, they offer both a light weight model mainly for wet screeding and a little heavier model for running on the rail or 2x4. I also was able to save money because I was able to buy direct from the Packer Brothers outlet store. I bought the 16, 12 and 8 foot blades

Re: Power Screeds


Back in the mid-90s I bought a Vibra Strike, the first one in the county for the occasional slab... never any problems except once poured a slab under cover in the rain and left it outside during the pour, wouldn't start after a downpour. I can't imagine anyone that does flatwork not using a power screed; rent or demo different models, see which suits you and buy one!

I used to use the grade stake method for wet screeding but I now use a laser, I think it is less labor... I don't set stakes, then pull and clean, pick up, carry, load, unload. I have the receiver on a short stick screwed to a small square plywood "foot" that keeps it always upright, never flops in to the concrete. Often if the floor above is framed I'll use a story stick, a 1x3 cut to the exact floor to underside of framing height for a elevation gauge.

Re: Power Screeds


The worst thing I have seen from using a power screed is the operator thought he could actually pull concrete and level.....nope. It is a tool, and only a tool, and not a substitute for an experienced rake man or two.

I will say it has saved our lives a few times on large pours when we were short handed. Mine is a 12, and when used correctly, with the right slump, it does about eliminate the need to float.

I recently took mine to our supply store for a tune-up and new throttle cable, etc., because we are having a hell of a time getting our concrete subs to actually show up, so I guess we will start doing our own concrete again. I have to get all the machines tuned up and then think about training my guys in placing concrete. I do not have a single experienced concrete guy any longer.

Re: Power Screeds


J you need to get a truss screed for all those buildings. Way faster than working by hand.

Re: Power Screeds


I have been thinking a lot about a spin screed. Something to consider. The length is a winner.

Re: Power Screeds


We have been using screeds for the last 25 years. Morrison Truss Power screed. 2 -10' ends, 4 - 5' sections, 1- 2' section. So, 42' max. 20' min.
It's really great, but you really need a bigger pour, to make it worthwile, setting it up. Takes some time. Once you are set up, it's great. Then you also have tear down and clean up. Usually we use a machine to pick it up, at the end, then move it to another area to clean up and break down.

Also have a Vibra strike. Thought it was the greatest thing ever. Killed my back, but still, greatest thing ever. Oh yea, 12' long. Also have several smaller screeds, but the 12' is the one used 99% of the time.

2 years ago I bought a Crown Strike off. I can't remember the exact name. 12' long. I feel like it's alot easier to run. The finish is the same.

To be honest, I've never been great at running it. Hurts my back. The Crown may be better, I've heard it's better.

For me, I always defer the machine. I grab a come along and get to work. I've never been embarrassed to admit I'm not the best at it. I can drag concrete like a machine. I just stay back, run the chute, then drag concrete. It makes a huge difference if the screed guy is good. You can drag that screed over the top of the concrete and it looks fine, but then you get a rain and realize there are so many puddles. Or high spots if you prefer.

Regarding spalling or the top flaking off, I've never seen it as a result of a vibrating screed. I've done alot of concrete. Never a problem.

I do see the top layer peeling. Since I wasn't there when they poured it, I usually assume it was something they did. I do see alot of guys using steel trowels on exterior concrete. Can't do that. I do hear guys saying they tell the plant to leave the air out. You can't do that. Usually the plant will put the air in anyway. Every wonder why they ask you if it's inside or outside? They are protecting themselves.

Get a 12' screed and you won't regret it. Run it good. Make sure you have guys pulling it down behind the screed. Don't try to drag the concrete with the screed. I see it happen. Guys start giving it more throttle trying to drag it more. Tell your guys, pull it down, wait for it to happen. The only thing you should have to do is kick a little mud in your footprints.

As a side note. I always make the chute guy pull concrete. If he dumps it out high or low, he's the one that will have to work. Never fair to have one guy run the chute and then let other guys do the work.
Of course if you have a bigger pour, let the best guy run the chutes. Once you find a good guy, even the laborers will be happy when he is riding the chute.
