Concrete Countertops

That is great news!

So, you are using motorized legs to raise it? That's kind of what I was saying (the hydraulics comment was intended to be humorous). The point is, you won't want to do it manually.

7' is a really long span for 1 1/2" thick concrete, and it's pretty hard to put rebar in a slab that thin.

In reply to SVreX:

2" thick looks like about 350 lb.

Just thinking about getting that from the garage to my office and then put in place on top of cabinets make me think I should go back to the ikea butcher block.

I am a little biased on this. I lived in Latin Anerica for a long time, where all counters are concrete, and considered cheap. I don't get it at some level. Seems like people are forcing a material that is not well suited for finish, spans, permeability, microbial absorption. weight, etc.

When I build them for customers, I do it old school, with my own mix. That's the way I learned in Guatemala and the DR.

But I will also admit I am not very familiar with some of the new high tech blends and mixes, which can better suited. I am just sharing some of my experiences in the past 39 years in construction.

It's worth a shot. I'd like to see the results.
