Concrete w/ embedded slate
I have a walkway beteween the house and detached garage w/ old slate tile just laying on the ground.
I'm thinking of making 2'x2' blocks of cement and embedding the slate into it.
I imagine I'd make some wood forms, place the slate tile in the form and then pour concrete over it. When the concrete dries it would be flipped out of the mold so the slate now appears on the walking surface of the concrete blocks.
The cement blocks would be 3" to 4" high w/ galvanized mesh for rebar. The slate that I currently have ranges ion thickness from about 1" to 2" and some are not very flat on the top. This uneven slate would probably result in a rustic looking block but I'm ok with that.
Your thoughts on this would be appreciated.
Some of the questions I have are:
- How heavy will these blockes be? Since I have to flip them over.
- The plan is to use regular plywood. Will I have a hard time freeing the cement blocks after curing? I was hoping I could simply flip them out.
- Do I have to use special wood? Will the cement cause the plywood to start falling apart?
The plan is to counter sink the concrete blocks so the are realtively flush w/ the ground. Can I just dig out enough depth for the blocks or would i have to dig our more and build it up w/ sand for drainage?
