Colinwell Shotblasted Concrete Masonry Blocks have matt texture, that exposes more of the aggregate used in the manufacture of the block and leaving a natural weathered texture.
Application
- Suitable for use in the construction of external and internal loadbearing and non-loadbearing walls, including the inner and outer leaves of cavity walls, party walls, partition walls and boundary walls.
- Can also be used as reinforced masonry walls through incorporation of bed joint reinforcement.
Description
Masonry block with a shotblasted face finish. Manufactured from cement, graded aggregates, an integral waterproofer and pigment.
Features and benefits:
- Versatile.
- Suitable for environments where robust, durable finishes are required.
- Good weathering characteristics.
- Complements other building finishes, including traditional facing bricks, curtain walling and rainscreen cladding.
- Water and frost-resistant, helping to retain a fresh, clean appearance.
- Cured by steam to give the blocks efflorescence-free performance characteristics.
- Manufactured in accordance with BS EN 771-3 and BS 5628-1.
- Minimal maintenance required.
- Non-combustible and will not contribute to the spread of flame.
- Blocks are efflorescence free.
- Available in a variety of colours.
