Telescope Reviews: Re: concrete blocks encased in concrete footer?

Mike,
Some time ago there was a test including cinder (or concrete) blocks. Even though they are not "cinder" they are porous. The result of the test was that originally the concrete appeared to adhere to the block without any issues. However with the blocks in place for weeks the mold was removed and the blocks were no longer firmly attached to the concrete itself. This lead the user to believe that adding the blocks was not a good idea. It was only a short cut. The main problem with this scenario is that once you do or do not pour the concrete into the hole with or without the blocks you are done. There is no way to know if the set up with blocks worked well. If you need I have extra concrete left over and can test this process again and photo document it. It will take me a few days to build a form and set it up. But I am willing to do it for you.

As Scott mentioned. If you are asking about shortcuts you know your answer. You already have all your required concrete for a complete pour. And you are installing the rebar, just make the rebar cage big and strong. You will be fine. My pier is 24 x 24 by 36 deep with the rebar cage. I originally thought about the blocks because I was lazy. I very quickly changed that plan.

Hope this helps some.
Clear skies,
