*Leaky waterfall got a total rebuild including new aquablox, biofalls, and liner instead of a small repair.
*Located near Minnetonka, MN
Sometimes old things just aren’t worth the money to fix them. Such was the case with this pondless waterfall near Minnetonka, MN. After showing up to simply fix it, the crew discovered leaky liner, sunked edges, busted aquablox, and a twisted biofalls.
What we did: • Brought in a mini excavator • Fully removed the old system • Installed a new vault, AquaBlox, liner, and BioFalls • Rebuilt the stream with natural stone detailing • Re-tested and tweaked flow • Recreated a beautiful, tranquil waterfall flowing through its woodland scenery.
Below are some before and after photos (and some construction).
Here are some finished pictures- many rocks were reused and blended into the rebuild waterfall.
Caring for this Waterfall:
Spring: Blow off leaves and debris from rocks, top off water. Trim back plants. Plug in pump.
Summer: Regularly add beneficial bacteria either by hand or automatically using a dosing system. Spot treat spring algae if it forms during hot parts of summer. Top off water if low during hot parts of summer (some will evaporate).
Fall: Net to keep leaves out or just scoop leaves off gravel near the lowest falls. Use cold water bacteria.
Winter: Turn off pump. Remove pump and store in a frost-free location if recommended on manufacturer’s pump directions. (I don’t remove the pump over the winter.)
