How to create a pond shape

Posted by wabbitpoo UK (My Page) on Mon, Oct 3, 05 at 12:23
| I want to create a pond in shape of a quarter circle. I tried in vain to find a rigid liner of the required shape so am thinking that a butyl liner could be the answer. I want to avoid creases and wrinkles so I wondered if I could make the shape of the pond from two sheets: one in the shape of the quarter circle for the base, and one long rectangle to form the two straight and one curved sides, joining all seams with some form of joining tape/adhesive.
So, is this a) feasible b) the best way and c) what tape and what precuations should I use? |

| Hi, This isnt the normal way to fit a flexible liner. because you would have to join the two liners together and the risk of leaks is huge. Use one piece of liner. I'm afrain you wont be able to get all the creases out and thats one drawback of flexible liner. However I think you can get lock liners made to measure so maybe they would make your shape up? Thanks, Daniel |

| You can get box liners made to measure. I expect that they cost a fair bit though. The link below is just one place that does them. |
Here is a link that might be useful: Box liner

Hi Wabbit,
I suggest using a small piece of cloth eg a handkerchief to try out folds.
I would suggest doing either one or two big neat folds at the square corner, and just allowing the rest to find its own shape with small folds. To neaten it you could stick the large folds, but it you arrange these so they are either vertical at the corner or at 45 degrees, they should'n look too bad. I don't think I'd risk trying to cut and stick 2 pieces together.
By the way, how big are you thinking of?
ps If you have folds, frogs and tadpoles love these to hide in. |

DO NOT try to seam one yourself unless you are handy or have the skills of a tailor or dress maker, as suggested either get a box liner or practice folds. If you want to practice in the real pond hole then use cheap plastic film rather than proper liner. Also if the proper liner is pvc be wary of working it in cool conditions it gets a lot less co operative when cold and forms those white crease mark folds quite easily if not worked so as to avoid them, I cant speak for rubber.
The folds at the centre of the 'circle' are in theory relatively easy, like folding a sheet of paper to fit INSIDE the corner of a shoe box and up the wall.
If you have flat vertical walls its a realtive doddle. Get the liner into the pond hole in approximately the right place and get into the liner. Start to fill the liner with water, 2 or 3 inches should be sufficient, ensure the liner lays flat on the floor. Once the liner is flat on the floor and ENSURING that the liner is right into the corners between walls and floor, drape it over the walls and onto the ground outside the pond hole. Make sure the liner is flat against the walls and work the surplus into one flap at the 'centre' of the circle, you may need bricks on the liner on the ground to keep it in place. Pull this flap out towards the outside of the circle and once you have a single neat flap you can do 1 of 3 things
1) lay the flap along one radii wall and leave it there 'infront' of the proper wall liner
2) reverse the sense of the folding and put the flap behind the proper wall liner
3) change the single flap to a pleat as seen in a woman's skirt and lay each half of the pleat along each appropriate radii wall again either in front of or behind the proper liner. I think the arc will end up a a series of triangular flaps or pleats. |

| Another option for a smooth finish is fibreglassing. |
