Hello building professionals,
I want to install smooth concrete columns as property boundary markers, between which I will build a masonry wall.
The concrete columns should have a cross-section of 40 x 40 cm (16 x 16 inches) and be 235 cm (7 ft 9 in) long, with 80 cm (2 ft 7 in) embedded in the ground.
We plan to set the columns with an excavator after they are cast. To do this, they will be supported on all four sides with concrete form ties and later concreted between the columns. The masonry wall will then be built on the strip foundation. Finally, the C50 concrete will be painted with a two-component coating, since we live on a federal highway where a lot of road salt is used in winter.
Could someone provide a reinforcement sketch for the columns?
The design should allow proper compaction using a poker vibrator (30 mm (1.2 inch) diameter) to remove all air bubbles from the exposed surfaces.
The entire wall structure is freestanding, so it does not have to withstand any unusual loads.

How should the connection between the fully cast concrete columns and the strip foundation look? Normally, the strip foundation would be cast first with starter bars for the columns. After that, the columns would be formed on the foundation. Since the columns practically don’t have to bear any load, I would place four 12mm (1/2 inch) bars in the corners of a bent cage, with external dimensions of 25x25cm (10x10 inches). Of course, I’m not a structural engineer! If you cast the columns first, special connecting reinforcement would have to be used, which would then need to be bent out after casting.
