General purpose, medium density concrete blocks.
Suitable for use in commercial and housing projects.
Can be used to construct internal walls in commercial, industrial and leisure buildings. The blocks can be used for the following:
The blocks can accommodate drylining, dense plaster, finishing coats and external rendering. Consult manufacturer for further finish recommendations.
Medium density, load bearing concrete blocks, suitable for facing and general purpose applications. The blocks consist of a specially formulated mix which reduces density, producing a solid block under 20 kg unit weight.
The blocks are medium grey in colour with a fine textured/ scratched surface, providing an enhanced key for plastering and rendering. Available in 100 and 140 mm widths, solid form only.
Features and benefits:
The mortar type for work above ground level should be designation (iii) / Compressive Class M4. Stronger mixes may be used only with the permission of the designer. Stronger mixes may also be required for work below ground in accordance with PD 6697. Consult manufacturer for details.
Movement joints should be considered in accordance with PD 6697 at approximately 6 m spacings. In areas of concentrated stress, such as those above and below openings, consideration should be given to the use of bed joint masonry reinforcement.
The design of walls should be in accordance with relevant design standards including BS 8103-2, BS EN 1996-1-1 and the requirements of the Building Regulations.
