Ira Posted June 10, 2007 Report Share Posted June 10, 2007 Ok, since I've finally got the **** pallets that were blocking my access to the bricks I wanted to make the pond out of(70 of them! Took me 4 months to chop them up!) anyway I will have more time off now, time to start doing some research... Anyone have any advice, instructions, links, etc for how to build a concrete pond? I'm thinking it'll be a fairly small one. L shaped maybe 2 meters on a side, half a meter deep, figure about 1500 liters. I was thinking I'll build a compacted sand base then surround out of red bricks and then concrete inside it. What would be good to reinforce the concrete with? Something like chicken wire seemed like it should work? Then I'll probably paint it with some kind of pond paint for extra sealing. Quote Link to comment Share on other sites More sharing options...
matt_man Posted June 10, 2007 Report Share Posted June 10, 2007 chick wire is a good start, use a morter mix with a poly fiber mixed into the mix and also a water proofer like sika 1 witch is also mxed into the mix. the higher the cement content of the morter the beter (less water penatration) Quote Link to comment Share on other sites More sharing options...
Ira Posted June 12, 2007 Author Report Share Posted June 12, 2007 Anywhere that might be easy to get the additives you mentioned? I was thinking that it I wouldn't need any special concrete if I painted the concrete with something to waterproof it? Quote Link to comment Share on other sites More sharing options...
Wok Posted June 12, 2007 Report Share Posted June 12, 2007 Stone and water world should be able to help you out. They have everything that a pond builder needs including sealing paint Quote Link to comment Share on other sites More sharing options...
Alan Posted June 12, 2007 Report Share Posted June 12, 2007 I think if I was doing a pond , I'd be letting it leach for a while and giving it an acid wash before I considered sealing it. This gets rid of the lime that will kill the fish otherwise. When building cowsheds we used a product called isinglas, used in the brewing of beer for clearing the fines, and my Mother used it for preserving eggs. What happens on concrete is that it goes on like water, and when it is dry, the concrete is covered with what is easiest to discribe as, glass. This can be done several times with it drying out between coats. If the milk can't eat it then it MUST be good. Quote Link to comment Share on other sites More sharing options...
Ira Posted June 13, 2007 Author Report Share Posted June 13, 2007 Heh, Stone and water world is a bit out of my area. Alan, I figured sealing it would keep the lime out anyway, so what's the point? Quote Link to comment Share on other sites More sharing options...
Wok Posted June 13, 2007 Report Share Posted June 13, 2007 I think stone and water world have a website you can visit Quote Link to comment Share on other sites More sharing options...
Ira Posted June 13, 2007 Author Report Share Posted June 13, 2007 Hmmm, They do have a website... Looks like all they have that might be useful is a mention that they have pond liner. Quote Link to comment Share on other sites More sharing options...

Caryl Posted June 13, 2007 Report Share Posted June 13, 2007 No I didn't. The problems arose when the builders tried to concrete around a post and found they couldn't seal it fully. Painting the pond with sealant worked excellently. Can't remember what the stuff was called but it had a rubbery feel to it when freshly painted on then it set.

jn Posted June 14, 2007 Report Share Posted June 14, 2007 Was it elastomeric paint? Quote Link to comment Share on other sites More sharing options...
markoshark Posted June 14, 2007 Report Share Posted June 14, 2007 Around the post, they should possibly have increased the height of the concrete to above the water level, which probably would have worked? From memory, the wood just goes straight to the bottom of the pond?" Quote Link to comment Share on other sites More sharing options...
Caryl Posted June 14, 2007 Report Share Posted June 14, 2007 Not wood. They made plastic pipes to go over it all. There are pics of it back in my pond thread. It still has a minor leak around one of the poles so we put a ballcock in 8) Quote Link to comment Share on other sites More sharing options...
