I remove the siding 1/4 in plywood from this wall. It is 25 feet long and 12 feet tall. The wall had slid of the concrete foundation and the bottom had rotted away. With help (very little) from my 68 year old brother. My brother can only walk 50 feet and only helped 2 or 3 hours a day. i repaired the boards installed a new seal plate jacked and moved the wall back onto the foundation. Install new 4 ft by 8 ft 1/2 in plywood and installed new hardy board siding. The siding is 12 feet long and 8 inches tall and weighs 27 pounds (12.25 kilos) per board. I used 40 of them. I carried cut and nailed them and my brother would hand me things as i needed and help hold them on the wall. I took me 32 hours over 3 days to finish. The last day i was up and down the ladder all day. A photo of the finished wall is below
I am 64 12 years with PD.
