Build your own waterfall?

Hi folks... I hope I am asking this in the right group... I am thinking of putting in a waterfall in my garden. Maybe more a cascading stream than waterfall.

The polystyrene block might be a good idea bu the cement coating idea is a no-no and I don't know what to offer as an alternative other than fibre glass.. The cement will leach into the water and add minerals which algae will thrive on. I suppose it is possible to seal the cement, but a 1 m high wall of cement will look pretty unnatural and I suspect if it is sealed nothing will grow on it to blend it in. Rob |

Build a big waterproof tray (or a preformed unit) and arrange the whole thing in it ! Must be strong enough for the big rocks. Or you can get a sheet of rock cut, and use this as an "edge" for the cascade. If pumping from a pond, don't underestimate the amount of water "absorbed" by the waterfall constuction. When the pump is off all the water will be in the pond, and the pond can almost run dry when the pump is started if not large enough. There are pond-building websites / books with rules of thumb for all this. Simon. |

Build your own waterfall?
Thanks guys....
The concrete was to be used to strength with the fibreglass over it. However, with the second option, I could just put the fibreglass. Not sure about the weight though.. I suspect I might still need something under it for strength. As for the waterfall absorbing the water, I have been thinking about this. Another issue is, ultimately, I want a little stream to a second pond (where the pump will actually be). This will obviously mean a lot more water is needed before it starts recycling. Waterfall needs filling, the stream needs filling etc. The bottom pond will be deep (for volume) but have shallow / rocky sides so you won't see the water level drop drastically. To aggravate the situation, I don't intend running the pump all the time. This means I cannot "get it started and top it up". Maybe I am being to ambitious |

Maybe I am being to ambitious Have a third "pond" - actually a covered tank of some sort. A small weir from the second pond to the third. So you pump from the third pond to the top. When that water gets to the second pond any excess over what fills that pond goes over the weir into the third pond. By being covered you don't notice the level of the third pond at all and that of the second remains static. You will also need to have a means by which the third pond can lose excess water when there is heavy rain.

The arrangement didn't work properly as the concrete was porous and had cracked, but the idea was fine.

Liner should be well above maximum water level all round and even be part of the same piece that lines the pond or at least with a major overlap. All the flaps and edges of the liner are hidden by rock work and planting. Pick your ricks carefully. Water should enter the fall at a few points , not just one hose at the top, he has a great example where the final fall into the pond is flowing a lot more water than the small stream apparently feeding it. Pond itself should be dug so that the bottom of edging stones are Below the level of the water, then the liner comes up the back of the stones and is tucked under the turf. Intial edge of pond should be a beach, with very slight slope covered in gravel and shingle, impression should be of the edging stones `floating` in the water when pond is full and beach allows for certain amount of level drop, importantly the liner is never left showing.

Build your own waterfall?
You have all been most helpful!
I've been thinking about this on my lunchtime stroll to the shops. I think I will build a box the rough height and width I want out of bricks. This allows me to fill the box with logs. A space to be used by critters at some point I hope. I can then shape around this with concrete. Once the rough shape is done, I can put down some of the underlay, some thick liner (I found 1mm rubber one) and then another layer of underlay, then finally more concrete to hold the rocks in place. Enough [real] rocks and pebbles and you will not see the main structure. What about concrete cracking? Would the fact that the liner is between two sheets of underlay resist tearing? Small cracks I would imagine would survive. Greater than 1mm I have a bigger problem. This will be the waterfall as well as the cascading stream down to pond 1. I can then have little stream to pond 2. Finally, I like the idea of the 3rd pond. Very neat. It'll have to be = pipe volume + Stream volume + Waterfall volume. Thanks for the links and info. Plenty reading for me to do In my mind's eye, I can see this clearly. Now to implement this! Anyone got any spare time? I have many spare beers (Well, not spare but willing to share) and lots of food. I'll provide everything, you provide help / expertise Cheers, Crispin |

Sounds good This allows me to fill the box with logs. A space to be used by critters at some point I hope. Whoa, logs will rot out , natural log pile somewhere mebbe but not supporting a waterfall. I can then shape around this with concrete. Dont want no stinking concrete, compacted soil and bricks are just fine. Once the rough shape is done, I can put down some of the underlay, some thick liner (I found 1mm rubber one) and then another layer of underlay, Geotextile or landscape fabric is what your after,stops root invasion into the liner, not frost protection fleece which is a lot thinner, under the liner. Use sand as well to form shapes and iron out creases. Liner is matter of budget, polythene wont last more than a season dont bother. PVC is pretty good on the price/performance ratio but isnt very stretchy,creases rather than moulds, and isnt very patchable if it needs repair. Synthetic rubbers like Firestone is pretty good. Butyl rubber comes in various grades , some butyl rubbers dont have very much butyl in them, it stretches, is repairable and lasts for ever, it costs as you would imagine. One of many: http://www.pond-liners-pumps-filters.co.uk/ then finally more concrete to hold the rocks in place. Enough [real] rocks and pebbles and you will not see the main structure. Look at the pictures on Paul Dyer`s site , lots of flat rocks that will stack, not random shaped rocks that end up looking like a pit bing. Natural stone paving slabs break up nicely for things like this and the rustic edging stones. Again geotextile where you need it to stop rocks puncturing liner and just enough sandy mortar mix to hold the rocks in place , concrete is for motorway bridges. What about concrete cracking? Would the fact that the liner is between two sheets of underlay resist tearing? Small cracks I would imagine would survive. Greater than 1mm I have a bigger problem. Dont use concrete ;-) Underlay is always a good idea, geotextile not old carpet it rots. Make sure your liner is well supported in firm soil with a layer of sand and underlay and it wont tear unless you put a fork through it. Concrete ponds almost traditionally leak and are often coated in G4 to kill the porosity http://www.arghamvillage.co.uk/produ...tails/180.html Bit evil to use though as its moisture curing dont want to spray it. Easy solution don`t use cement for sealing ;-) This will be the waterfall as well as the cascading stream down to pond 1. I can then have little stream to pond 2. Finally, I like the idea of the 3rd pond. Very neat. It'll have to be = pipe volume + Stream volume + Waterfall volume. Remember to put plumbing and wiring in for lighting before you start mortaring things into place.... Adam Thanks for the links and info.

Build your own waterfall?
Adam, Charlie - thanks.
I know the issues with cement / concrete / mortar. As water proof as a slice of toast. My last place had a homemade pond / waterfall which leaked like a sieve. I eventually left it alone / dry. This is why I want to get this one right. The logs mentioned are just for incests / to fill the space. Not load baring at all. Again, thanks for the tips. Now I'm getting excited about it..... One (one of many) questions that has popped into my head now is where pond 1 goes into stream. I saw special glue to bond PVC liners. I assume you can get the same stuff for the butyl rubber. Even a large overlap, capillary action would suck it dry. Think I'll go re-read everything tonight. Then, I'll write a book (Credit to you all! Cheers, Crispin |
