Jerry Rigged
Deciding we needed to line the upper ponds in concrete, we
thought we better have a way to drain the pond. This necessitated the Jerry-rigging of a
bulkhead fitting. The local hardware store threaded a 6" piece of 3/4" pipe
twice as far and with about a 2/1000th smaller thread. This allowed a pipe flange to be
threaded on and have the excess pipe threads protrude beyond it. As shown in the picture,
the assembly threaded into the other pipe/pipe flange combination. A angled lateral drain
pipe exited out the bottom of the fall's wall. Two 45's let you adjust the angle
precisely from 0-90 degrees and make it easy to get a perpendicular drain pipe. |
And Then We're Screwed Up
Both flanges were thoroughly coated with Marine Goop
and the rubber liner was installed in-between the two flanges. The upper flange was
threaded into the other half. It could then be tightened down to compress against the
liner. A cap was put on the exit pipe to plug the drain. It would be possible to pipe in
water from the bottom to create a fountain in the middle of the pond with an extension and
a fountain head.. |

Fall into the Gap
There are large voids and sharp edges when using irregular
broken concrete. Spray foam sealant was applied between the first plastic liner and the
wall. |
A Little Mustard and We'd
have a Sandwich
Plastic sheeting was put down, then carpeting and then another
layer of plastic sheeting. |

Reinforcements Arrive
The EPDM rubber liner was installed and then pieces of expanded
metal mesh were lined into the pool. The mesh is used to stucco and i thought it would
make great reinforcement and would help to build up the nearly vertical walls. |
This Is Almost Like Work
We mixed the 37 bags of cement with a cement mixer (thanks
Curly!) and troweled it up the sides. It's about 3" thick. Some places to put
plants have to be installed, the top edges have to have their final finish, and the
waterfall weir feathered out with patching cement. The far end is the "head" of
the river and is going to be landscaped with rocks.. |
