This will be one to follow, this pool is in a Yoga retreat near Kenthurst and they wanted a natural waterhole. We are using the natural rock to make a waterfall, sound easy enough but we have to seal the rock face and its only because it is solid that we wont have erosion. We are lucky that the rock naturally runs the way we want but we know how well it works till we turn it on. another tricky one.
