anyone here pour, finish or set concrete forms?

just wondering what you use for forms.

for driveways we use 1x4's and a metal interlocking keyway joint. most others around here use treated redwood 1x4 for a join. (no pun intended) but in 5 or so years it rots out and grass and such can grow up through it.

for say a building slab or house slab instead of 2x12's we use a 1foot form. build a frame that is 1foot and put a peice of plywood on the front with a 1 3/4 inch lip above it. every two feet we have a spacer block put in. set that bad boy on the ground and put a steak in at ever spacer block. we use a laser transit to shoot them to grade as we nail them up. and a 2x4 going from that stake to the ground for a kicker. then our back ho digs a 18" footing down the side and beams across the slab. we use post tension cables instead of wire. once its all up we put a 2x2 across the top on the inside.. this is for tin ledge for a metal frame up building or a 2x6 for the brick ledge. this way when all is said and done you dont have a gap or a space showing under it all. a week after its poured they post tension people come in and pull each cable putting 33k lbs pressure on each cable locking it in.

cracks vanish .. you can put a cig paper in a crack and once its pulled you will never get all that paper out. heh thought it was cool frist time i saw it done.

if we dont use cables say like on a drivway. we use either wire mats or fiber. fiber in concrete is iffy to me.. sometimes its nice others its a pain.

longest time on a job for us is squaring everything up to set forms. after that we get done from 1 day to a week depending on the type of job.

btw flyash is a pain in the arse. here in louisiana they require concrete companies to put it in the concrete. their way of getting rid of it. this results in longer drying times and once your done get cleaned up that crap will eat ya clothes and skin for some reason.

most companies doing forms work thier wood into the total cost then junk it all afterwards.. hell we build our forms or use lumber over and over we usually get 12 jobs off a board long as it dont break or we have to make special cuts.

anyone need help with concrete forms or ideas they have let me know ill provide what i can to get ya started.
