Video showing the process behind building the stone tunnel that I often use in cascade construction. The most important point is to always ensure that the liner comes far enough up the sides of the cascade / stream and tunnel to eliminate any chance of leaks from anywhere in the system. When constructed, the tunnel should be strong enough to stand on - Do not try this if you have even the slightest doubts about the structural quality of the tunnel. Please feel free to rate, comment and send me any videos of your own projects.
