I would like to extend my existing 12X12 cement pad.
With my back to the wall of the house I want to go out 4feet on the left side and 4feet in front of me.
In front me there is a slight hill. I will have to put in a retaining wall.
My question is...
Can I pour the cement pad right up to the retaing wall top flush (and make it level) basically water would roll right off the pad and the top of the retaining wall to the ground.
