How to Put a Header in Block Wall

Adding a header to a block wall is a great way to enhance its stability and aesthetic appeal. A header is a block that is laid perpendicular to the wall's face, which creates a bond between the two faces of the wall and helps to distribute the load. Headers can be used in various ways, such as creating corners, openings, and supporting lintels.

To install a header, you will need the following materials:

  • Concrete blocks
  • Header bricks
  • Mortar
  • Trowel
  • Level

Here are the steps on how to put a header in a block wall:

  1. Mark the Location of the Header: Determine where you want the header to be located and mark it on the wall with a pencil or chalk.
  2. Prepare the Mortar: Mix the mortar according to the manufacturer's instructions. The mortar should be a stiff consistency so that it can support the header.
  3. Install the Header: Apply a layer of mortar to the top of the block where the header will be installed. Place the header on the mortar bed and level it using a level. Tap the header into place with a hammer.
  4. Fill in the Gaps: Fill in the gaps between the header and the blocks with mortar. Use a trowel to smooth out the mortar and remove any excess.
  5. Cure the Mortar: Allow the mortar to cure for at least 24 hours before applying any load to the header.

Here are some additional tips for installing headers in block walls:

  • Use a level to ensure that the header is level. This will help to prevent the wall from leaning or collapsing.
  • Use a stiff mortar mix to support the header. A weak mortar mix can cause the header to sag or fall out.
  • Allow the mortar to cure for at least 24 hours before applying any load to the header. This will give the mortar time to harden and gain strength.

By following these steps, you can install a header in a block wall correctly and safely. Headers are an essential part of a block wall, and they can help to improve the wall's stability and appearance.
