| Russel, if 3 months is not the usual time for concrete to crack, then what is? Perhaps I could have spent thousands of dollars, hired a structural engineer and found one of the "few 'clueless' professionals that are accepted to follow a very specific methodology and created a replica of the Hoover Dam"!! Then I could have spent another thousand or so dollars (which I did with Pond Armor) and Epoxied the walls. That would have really assured me a solid surface for -----(Fill in the blanks for the number of years) But then again, we all know that even the Hoover Dam leaks a whole lot.
The point of this argument is not that there are a million ways to make a concrete structure. I am sure if you ask ten people who’ve ever built a concrete pond, you will get 10 different opinions. The point here is what is the best and most cost effective way to create a tank that would hold water for a very long time without leaks so that we can enjoy our Koi? No offense to anyone on this forum, but I am more inclined to believe a concrete professional who works with this stuff every single day when they tell me that they have never seen a concrete structure that did not crack over time. We all know that when the concrete cracks, so will the Epoxy liner!! That is why the only solutions I see as long term are EPDM liners or Polyurea!! |
