| 1271335 | 2012-04-23 10:18:00 | Didn't we have a saga on a certain water tank a couple of years ago? Make sure the new one has big air vents. :D :D Huh? |

| 1271336 | 2012-04-23 14:55:00 | Blocks laid with their seams right over the seam underneath it are structurally weak . There needs to be overlap, preferably by 1/2 the block's width . Then the question: is there any rebar inside the wall - perhaps a bond beam? It needs to be tied together with more than mortar and good intentions . Do I see some sort of tie bolts in the rust reveals in the blocks there? Was there a false floor attached to it somehow? A square tank - in and of itself - isn't inherently weak or weaker, especially if it's not terrifically deep so that the pressure isn't too high, but a round structure is always stronger . At about 1lb pressure for every 2 feet of height, the outward hydraulic pressure can be guesstimated well enough . All said: that wall isn't gonna be any good for conversion into a tank as far as I can see . I've built some tanks out of block before, a few were six feet high, and all I did was apply an asphaltic emulsion to the inside for watertight integrity . Not for potable water though as the emulsion could slough off and contaminate the water . |

| 1271338 | 2012-04-24 09:28:00 | Personally I'd rebuild it a bit, Make sure the bottom is strong . I'd dig some deeper foundations that are strong and sound, also if the bottom is below ground it will be stronger (pressure highest at bottom, but pushing against dirt) and you and you will have a "sump" where sediment can settle . Make it water tight as possible and line with PVC tarp, similar to the sort used for fish ponds and the like . Do this by cutting to rectangles and sealing together with a heat knife . . . not sure what it's actually called, or maybe some plastic sealant . Make sure there is drainage under the plastic liner so if it leaks the tarp doesn't balloon up with the water . Don't be disheartened by the current messy wall, at the very least you could tidy it up and make a new working one . Maybe build a concrete slab bbq . If you have an old gas bbq you can take the burners and grills and put them in . I did that with the BBQ I built . You can use the gas to cook, or take the burners out and load in some wood to cook or just have a nice fire to drink around . Good ole man jobs, making extra work out of something that should never have been work . It's why blokes exist and why our houses are great . |
