I am going to build a block pillar 6-7' in height using 6" block to support 6' side gate and fence panel

Question

I am limited with depth of ground due to mains pipes etc. How deep and wide should I lay the concrete foundation?

Answer 1

meter i think!!!

Answer 2

all footer depth questions will depend on the type of weather you get in the winter...in northern pa where i live i dig all my footers 32in. deep. then i pour 8 in. of concrete and lay 3 courses of block to get to ground level...if you are only using 6 in. block you better put vertical re-bar and grout them...

Answer 3

3 1/2 -4 feet nothing less that is enough to get the job done
