00:00well welcome back again to the maybe those concrete jobs that you're anticipating doing
00:15and this is a called a concrete vibrator now these are used in a lot of cases in a wall walls
00:22certainly in larger pores big big foundations and the purpose of a vibrator concrete vibrator
00:31is to get the air gaps out of the out of the concrete when you pour it there's a lot of times
00:36sometimes with the stone and it could even be not as quite as fluid the concrete pour as you would
00:43like and once you pour it you can end up with these air pockets inside and inside your concrete
00:50and thereby you'd want to vibrate the concrete and thereby closing those up and making a solid
00:56concrete wall foundation wall or or a footing for one of your projects that you're doing now
01:06a common one is the walls of a house in the days of block of course you don't need it but when you're
01:14pouring a foundation wall you would use something like this one here maybe about an inch and a half
01:19size head now these cables here these particular ones are about 10 feet long because normal walls
01:26are eight foot foundation walls so you would use something like this size here and if there's a rebar
01:33in the wall you need some you have to pick the size of the head that'll you best suit so that you're not
01:41going to get it stuck into your into your wall and also give enough vibration that you need so you can't
01:46you don't want to use a larger head in a in a say an eight inch poured wall like this which is about
01:51two inches or you'll get it stuck in the in the wall in the rebar so they come different lengths they
01:57come different sizes you have to utilize the one that's best for your project and usually your rental
02:04store will know which one works best for when you explain what you're doing this is the motor it's electric
02:09motor just plugs in the other end of the head on these cables you're just lifting this T handle here
02:20shoving it in and locking it a pin will go in these holes here so it's fairly simple to hook up and then
02:26you're gonna be holding this end with one hand and the your hold your cable end with the other hand once
02:33you turn it on that cable that head is vibrating and not good to turn them on is unless they're in the concrete
02:41itself or in say in a bag of sand or something if you want to see how it's vibrating but not a good idea just
02:47to leave it there sitting on the floor sitting out on the job and turn it on out in the open air so a larger head
02:54like this here might be used into a larger pour maybe a three a one meter square footing or something fairly large where you
03:01need a little more vibration but you've also got more room for the head with whatever guards regarding
03:07the the the cage of reinforcing rod that you're using as well keep that in mind so once you're done
03:15of course everything wash everything off and it'll be ready for the next job but this will be a big help
03:21when you're doing some of these foundation walls or larger pours for mostly vertical pours not
03:28don't they're used too much in the you wouldn't use them in flat work like driveways stuff like that patios
03:33but if you were building a whole concrete step poured concrete then you would probably use a vibrator
03:39so there's something else to consider in your concrete jobs and we'll see you again soon and don't forget to subscribe
