I just bought a home in Santa Fe, NM and am in the process of converting a room into a workshop.
The floor is slab on grade and looks like it has been in place for at least 20 years. In the middle of the room there is a 3.5" step down to a lower slab.
I was thinking about pouring concrete to match the level of the higher slab and then use a self leveling finish across the whole room.
My plan is to put down tar paper so the new slab doesn't bond with the old and use re-mesh as my reinforcing. The articles I have read also recommend using a concrete mix which is sand and cement and no coarse aggregate. It looks like it will take about 24 cu. ft to accomplish the project.
I think I have thought it through pretty well but I want to put it out there and see if anyone has advice or recommends doing the project a different way.
Thank you in advance,
