Placed the last layer of crates …

Time for Christmas Eve! Well we have a lot of wrapping to do…. Wrapped, folded and trimed the polyfelt first. Next the rubber was folded up the sides and the extra rubber in the corners folded neatly.

We formed a couple of pipe connections for expansion at the bottom right and overflow at the top left. These were sealed by cutting a half-sized hole in the rubber and stretching it over the pipe. This formed a ring of rubber about 2cm along the pipe which was covered in a stip of geo-textile and clamped with a stainless steel tie. The overflow level is 40mm from the top of the tank.

Finally we wrapped up the outer geo-textile and added more geo-textile as a lid. The access shaft was installed last.
