The blocks and the building system form a fully insulated load-bearing wall. The method applied is very similar to building a masonry blockhouse. Reinforcing steel and concrete are placed at certain intervals, either side of openings (ie: doors and windows together with a bond beam.

The blocks are a mix of hemp (84%) and lime (16%).

Cladding, plastering or rendering the surface of a finished wall can be applied immediately. The blocks are the perfect option for many applications such as small renovations, new homes, infill and internal walls.

Due to the high fire rating they can be used as a fire separation wall and are ideal for construction in bushfire zones.
The HBA building system is fully engineered and compliant with Australian standards and building codes.
