Wow! Very impressive! :thumbsup:poured 38x30 five inch today by myself. It was 86 degrees so I did have to hustle.
Really?How are you pouring it? I would pour two 15' pours on 2 separate days.
Pictures please or else it didn't happen :laughing:When it comes to striking off form to form or form to pipe you need to look critically at the shape of your strike off. The wacker L has a 90° front face. It is a wet screed it won't push itself down to your form. You need something that has more of a wedge up front. There are several brands but I only have vibrastrike so that's what I know the best. The bevel on the front will help force the strike off down against your form or pipe. I have a wacker L but it never gets used except rarely when wet screeding in a tight space. When you bull float do it perpendicular to the direction you struck off. Run a steep angle at first to push any ridges down from the strike off then flatten out. It's pretty flat off the strike but the float will make it dead nuts.
We try to use grade pipes whenever possible. It'll ensure an accurate pad whereas wet screeding is purely operator skill. When the pours get over 20 ft try to use a truss screed whenever it fits. I haven't pulled a board in about 10 years and don't plan to again. You can build a pretty good mule strike out of an old lawn mower deck. We did that clear back in the 80s, people thought snapper made concrete tools. You need the deck and handle and some round pieces of steel to replace the blade. Weld on some angle iron on the front and back where the wheels were and C clamp your strike boards on. 2x6 work best. I still get out the mule on long sidewalk pours. If we have a couple hundred feet to do that old girl lays it down fast and flat. Ours is modified so we can attach a bull float right to it. Strike and float 4-6' sidewalk in one pass. Hit with the walking edgers then cutter and Groover finish with the walking trowel to take out the line and broom. 5 guys can pour sidewalk as fast as it'll come out of the truck.
I do pretty much the same, the day before I set pins with the laser, but I use 24" form stakes and put a peckerhead nail through a hole, set the pad off the nail, pull the wet screed and then pull the stake.We always use pins and wet screed between them. It is always 1 guy's responsibility to drive the pins down.
