Wanted to post progress on my pondless waterfall build in hopes that if experience builder might help with eliminating costly mistakes you may see.
Thanks In advance
25’x50’ 45mil lifeguard liner and underpayment
2x 26” big Bahamas pro spillways
1 AP 12500gph submersible pump
1 pentair 3hp variable speed external pump (230v) 10200gph
3” pvc pipe 90’ total
40w UV sterilizer
20 eco boxes (sump)
1 sump vault
Sump size 4’x10’x3’
Rocks are huge. Set all with excavator and straps. Going to mortar all cracks and spillways to help with settling
Little worried about weight of rock on liner. Did use extra underlayment on bigger stone or sharp edge stones but not sure if shear weight will rip liner.
Also when setting stone. Some sections of liner would be pulled tight or create sags in liner. Tried to relive pressure by resetting stone but almost impossible to avoid.
