It hard to tell from your last two pictures, but it looks like you've left a wee bit of space... between your fence and the new, redone, stone/cement work.
I'm sure you probably already know this Davy -
Cement and wood should not have direct contact with one another. The reason being, cement retains moisture, and moisture rots wood. I've experienced this type of damage, firsthand. It destroys wooden structures. Some insects thrive in such an environment, and will compound the problem.
A foam gasket is usually used to separate the sill plate from the cement foundation, when building/framing a house.
