HI All, we are looking at putting a screen at the top of a retaining wall and walkway to hide the view of the tank along a verandah. Any hints on how to securely attach a Herringbone Hardwood Screen Panel 1800 x 900mm? Would posts in the dark gravel around the tank base, be the best and easiest solution? (See second photo). The piping shown sticking up and cut off, was for a gas connection for a pool heater. Thanks in advance for your assistance.
