ᐅ Rectangular Small Pond Next to Patio – Tips and Ideas?

Hello!

I am planning a small rectangular water basin next to the terrace.
At first, I wanted to use a prefabricated plastic basin, but it would have to be partially buried. Otherwise, it would be too unstable and would need additional support.

Option 1:
Place a PE (polyethylene) prefabricated pond at the desired location. However, I can only half-bury it because the substructure for the wooden decking still requires some build-up. I might also set some edging stones in concrete around it for stabilization.

Option 2:
Build with shuttering blocks, reinforce, and pour concrete. For this, I would need a pond liner, and I have no idea if I can install it wrinkle-free in a rectangular basin. It’s definitely more work, and I don’t have much time… plus, there’s still a lot to do in the garden… 😀

Option 3:
Use shuttering blocks and instead of a liner, work with a two-component waterproofing slurry. For this, I would have to pour a concrete base slab. Everything would have to be perfectly level to get the final height right. I’m not a landscaper, so this seems quite demanding for me.

I’m leaning towards option 1. It also allows more adjustments if things don’t turn out as I imagine. Once the wall is concreted, it’s much harder to change.

Does anyone have another idea?

Watch out for mosquitoes attracted by standing water 😉

Seal the inside of a large, old handcart (originally used as a donkey cart) and fill it. Add a few plants inside; it looks fancy.

How large should the trough be? Do you plan to plant it? Depending on that, you could also use a large mortar trough; that’s probably how I would do it. It can then be recessed or clad and is sturdy. There are chemicals available to keep mosquitoes away 😀

I have no concerns about mosquitoes. There will be some splashing anyway. And there is also Neudorff mückenfrei.

Already somewhat larger than a mortar tub. Currently, I am considering a 380L (100 gallons) prefabricated pond.

Personally, I would go with the pond liner, but since you have little time, option 1 is the most suitable.
