How to Lay Out Rebar for Hollow Tiles

Walls in a stone house or business building are based on hollow tiles made of cement. These tiles are used to add support to the building while keeping the weight to the lowest amount possible. The tiles are not flat like floor tiles but hollow square blocks connected to each other with a layer of cement. To add support and strength to the wall or floor, reinforcement bars, or rebar trusses, are added to the connecting cement between the hollow tiles.

4-inch square rebar chairs
Tape measure
Reinforcement bar trusses
Cement mortar

Instructions

- 1
  Place a square rebar chair along the wall space every 2 feet with the flat chair head parallel to the wall space.
- 2
  Pour a 2-inch layer of cement mortar into the wall space. Cover the bottom of the rebar chairs. Allow the mortar to set for 3 hours.
- 3
  Set reinforcement bar trusses into the chairs, laying them down flat. The trusses will start on one chair and pass over a second chair to stop in the middle of a third chair head.
- 4
  Start a second reinforcement bar truss in the second half of the rebar chair head. Continue to place reinforcement bar trusses until the entire wall space is filled.
- 5
  Fill the wall space with cement mortar up to the reinforcement bar trusses. Do not wait for the mortar to set.
- 6
  Set the hollow tile on the reinforcement bar truss at the beginning of the wall with the U-shaped bottom of the tile straddling the reinforcement bar trusses. Continue to place hollow tiles along the wall space.
