Blockwork refers to the construction of any structure with concrete or cement blocks. Concrete blocks are typically rectangular, grey in colour and larger than a standard clay brick, with a hollow interior cavity. This improves their insulation capacity and makes them lighter to work with. Blocks have become a popular alternative to traditional clay fired bricks, because of their convenience and cost effectiveness.
Concrete blocks are utilised to construct a wide variety of structures including commercial buildings, residential homes and garages. They are popular for their enhanced fire resistance, thermal insulation and durability, though they are generally not left bare for aesthetic reasons. In the residential setting they are often used to build the partition walls in a home, retaining walls in gardens and to line vegetable garden beds.
Blocks come in a variety of densities, and should be matched to the required application. High density blocks are typically made from cast concrete and aggregate, whilst lower density versions utilise fly ash or cinder.
Concrete is a versatile material with a range of advantages for building and construction applications that includes:
