Concrete – the easiest way to cut a 2 inch groove in concrete

concretecuttingirrigation

I have a 5 foot wide concrete side-walk running next to my house. I want to cut a 2 inch groove from the wall to the yard in order to run a PVC irrigation pipe from the faucet on the wall to the trees. The primary question is:

What is the easiest way to cut that groove into the side-walk? (i.e. what tool will I need and how do I use it?)

Other questions:

Can you think of a better way to run irrigation from the faucet (that you see further down the wall) into the garden?

What other problems am I going to run into and how can they be avoided?

I'd try to go through the slab and then below it. Most slabs are 6" thick with gravel underneath.

You can rent a concrete core drill for around $60 from home depot. Stick a hole in your slab.

Then you can use something called a 'sidewalk sleever' to tunnel under the slab. Then install pipe (a little tricky due to the elbow, and fill your hole back up with gravel.

The end result will be much prettier and do less damage to your slab.
