What is the difference between an H Block and a standard concrete block?

The open-ended design of an H Block is better suited to accommodate horizontal reinforcing steel and concrete. Standard blocks have a dual-core design, which makes it more difficult to install additional reinforcement.

Do H Blocks need to be filled with concrete?

Yes. Most of the time, H Blocks are designed to be filled with concrete after the reinforcing steel has been installed. These blocks are designed to accommodate additional reinforcement and improve wall strength.

Where are H Blocks installed in a block wall?

H Blocks are installed at points in structural blockwork where additional horizontal reinforcement is required. They are often installed at the top of walls, above openings, or at specific levels within walls that require extra support.
