The trouble was that after a few years the pond leaked, and also filled in with rocks, and dirt.
I consulted my go-to person Danny Toy who suggested that we make the pond out of a material called Gunite which is sprayed on to a substrate such as what we did rebar over dirt with wooden forms and sticks.
BTW: Gunite is very porous and always has air pockets, so it exchanges water easily and will need to be sealed up
Pond all formed up with rebar
Here is the pump, the big truck is one massive compressor
Here is the concrete truck pouring into the funnel
Here is the team spraying
Shaping the concrete
Here is the pond all poured and shaped with Danny Toy
Cut to a few days later, the form elements are removed
Here is the drain end of the pond
Here is the fill box
Here is the completed outflow box
This is a detail of the pump in the fill box
To prep the fountain to be painted, we built a tent to keep the surface clean and hold in the heat
We used a propane heater to dry out the Gunite and heat it up to be the right temperature to paint
The heater takes a 24 gallon tank of propane
We had to dry out any of the wet spots with a torch
We consulted Danny Long at Warehouse Paint who after talking to the UGL rep, just to make sure, recommended a product to use and gave us advice on how to prep and paint the pond.
The surface was prepped by lots of scrubbing and rinsing with a product to open the pores, we did this process 3 times, scrubbing hard each time, and then followed with lots of rinsing, and pumping out the rinse water.
We then gave it 3 coats of UGL DRYLOK Extreme tinted to be blue-gray.
Here is the finished inside
Here is the finished pond with the plants transplanted back into it in baskets to control their spread.
The plants have begun to spread and take shape.
