Hope I'm posting in the right section of the forum now.
This summer I plan to cast 2 countertops, they will be at an angle, like an L.
I would preferably avoid a seam, so I got an idea yesterday about possibly casting them together. So my thought was this: after casting and flipping the countertops, you widen the seam, say about 10 cm, set up a form underneath and on the sides, and fill it with expanding concrete and rebar.
Once it has cured, you sand the countertops as a whole and treat them. It should be noted that they will be outdoors.
What do you think about that?
Risk of cracking? Difficult to make it look nice?
