We want to build a table with benches outside.
For this, we have a concrete base with vertical rebars (40cm out of the ground).
We want to build brick columns for the structure of the table/bench (50/80 cm high).
Inside the brick columns, we would pour concrete (so it would hold the rebars, bricks together).
- Do we need to completely separate the concrete base from the brick columns/concrete in the columns?
- OR: we just need to put bituminous plates under the bricks and not the concrete in the center of the brick columns?
