Hello all,
I am taking @Lisak1's advice and starting a new thread about my pond build.
6 Years ago I wanted to make a water feature while doing the garden and ended making a concrete form for a pond. Soon after, our family grew by 2 and focus changed. This is the year I want to finish it and if there is a great error in my design, hopefully someone will notice it before it's to late. I am open to suggestions and comments.
The actual pond holds about 6,2 cubic meters of water, the depth is around 0.7m, with a slight drop towards the bottom drain. The bottom drain is connected via a 110mm pipe to a settling area with a volume of about 0.7 cubic meters. One or two underwater pumps will be housed here, and they will service 2 water falls, and 2 bog gardens.
The bog gardens will be built above ground and hopefully they will be able to filter the water.
I would like to have 2 koi fishes in the pond, or at least some gold fishes.
This is the way I designed it to look:
At this moment I pressure washed the concrete to see it's condition. My initial idea was to use a concrete based waterproofing suitable for drinking water tanks, but it only comes in gray and white and from what I read black is preferable.
I am thinking of using a pond EPDM liner now, all internal corners made using the fold technique, and the 3 outer corners using seams and form flashings. I will need to glue the liner to the concrete to make it stay in place. To address the shrinking problem I will be installing some stainless steel corner brackets covered by some form flashing tape.
The pond has a cave like area under the deck, concrete ceiling also, it's going to be very difficult to fold the liner, but hopefully it will work.
After making it watertight, I will build the bog gardens partially above the settling area, partially above pond area.
The bogs will be around 10% of the pond volume. Reading @combatwombat's post in another topic, he opened my eyes to the problem of flow rate in the bog. My original idea, the pumps would push water in the bogs and water will overflow as 2 waterfalls. That sounds like a bad idea now, because the water will linger in the bog way to little.
So the waterfalls should be separated from the bog.
I could not find ready made container for bogs so I am thinking of making them out of OSB lined also with EPDM.
The waterfall height will be 0.7m, and 35-40cm wide.
This is it for now. I hope to structure my thoughts better with this thread and in the future, others can use it for info.
