Block wall fence
Can anyone tell me how a block wall fence is built? I am talking what we call cinder blocks here.
Does it need a footer?
Below the frost line (if so, the entire length or just every so often)?
The soil (or lack thereof, almost all rock) where said fence/wall would be constructed is very difficult to dig, with machines. I would hate to have to dig 3 feet down or more. I live in Pennsylvania.
A web address would be alright too. Thanks in advance.
