Small Waterfall - water dripping behind ledge

[chris22]

Hoping some of the more experienced here have a simpler fix. We recently cleaned out our waterfall and finished stacking all the rock, siliconed the spillway edges where the water runs down, but now have an issue with water running under the spillway rock and dripping down. It causing water to run down both sides of the rock and soaking the ground.

Does the spillway ledge need to be sharper to prevent water from dripping under it? The water flow is pretty fast, so I didn't think slow moving water is the issue. Not sure what to do here. I've attached a couple pics for reference.

Hello and welcome!

We have many waterfall experts here — but I’m not one of them. Is this a pondless feature?

 

[chris22]

There is a small pond/basin which the water flows in to. Its not used for fish or plants, mainly just a tub where the water collects.

unfortunately natural rock spillways tend to do a bit of this, is the water physically leaving the feature?

Its slow leaking out of the left and right sides due to the dripping

is there no liner behind the waterfall?

Wherever you have water, you need liner under/behind it.

remove the stone where it is leaking / dripping . and cut a slot at least a 1/4" wide and 3/16" deep this will create a dripping point and not allow the water to run and get past the liner

I have the same issue.
