We dug the 5'x5'x6' hole for the tower Saturday and have the concrete truck coming Monday morning. QTH is south Florida, soil is a dark loamy consistency with plenty of sand content. The sides seem t
I would leave it alone....sounds like it is slightly oversized already....as far as aesthetics goes - be prepared to form a "top" where the slab extends above the ground....I would not pump any stand
I'm sure the driver of the concrete truck will have seen this before. Offer him some money to help you pour, and you'll get his advice for free. My guess is that Jim is right, but I'd think about pum
.....I would put some plywood in there if I could, but the rebar cage is set and there's no way now. I'm not worried about pouring concrete into the hole with water in there, I know that it will be d
As the concrete is going in I always continuously stab the pour with a round point shovel - just to make sure there are no voids created... I really doubt you need worry about pumping the water - the

If it stays at a foot of water, I wouldn't worry about pumping it out, = if is more than that, we suggest pumping it. also we suggest renting a = concrete vibrator from the local rent it store, this
SAY WHAT? It will just take longer for the concrete to cure - which is an wonderful thing! The ultimate strength of concrete is greater the longer it takes to cure - during the initial phases of curi
That's wrong. Concrete is stronger when mixed with less water. I received a private reply from someone who does this for a living. He said that you won't get much mixing pouring under water. Therefor
The vibrator advice is a good one a small job like this one can be done without it but if it is accessible why not use the right tool for the job Randy AC7NJ --Original Message-- From: towertalk-admi
TT: I agree with Randy (again) that David ought to rent a concrete vibrator - this will aid in getting the entrained air out of the mix, resulting in a stronger pour. However, this compaction by the
I've posted this to the reflector several times before and it is in the archives, but here it is once again! Concrete is a mixture of two components, aggregate and paste. The paste is comprised of po
