Close texture concrete blocks

 (a) Dense close texture blocks – 100mm/140mm/190mm 

Stowell dense close texture blocks

Stowell dense close texture blocks are made with a maximum aggregate nominal size of 3mm limestone. They are made with round arrises along the 440mm length, which, with approximately 12mm mortar between the blocks can make the horizontal joints appear larger than they are.

 (b) Stowlite medium dense close texture blocks – 100mm/140mm/190mm 

Stowell dense close texture blocks

Stowell medium dense (Stowlite) close texture blocks are made with a maximum nominal size of 5mm lightweight expanded clay aggregate. They are made with round arrises along the 440mm length, which, with approximately 12mm mortar between the blocks can make the horizontal joints appear larger than they are.

 (c) Midi dense close texture blocks – M290

Stowell dense close texture blocks

Stowell M290 Midi dense close texture blocks are made with a maximum aggregate nominal size of 3mm limestone. They are made with round arrises along the 215mm lengths, which can make the vertical joints appear larger than they are.

 (d) Midi dense close texture blocks – M440

Stowell dense close texture blocks

Stowell M440 Midi dense close texture blocks are made with a maximum aggregate nominal size of 3mm limestone. They are made with round arrises along the 440mm length, which, with approximately 12mm mortar between the blocks can make the horizontal joints appear larger than they are.


Stowell Concrete’s close texture blocks can be used in commercial, industrial, leisure and academic buildings.
For both 100mm and 190mm wide walls, we can offer dense and Stowlite close texture blocks.

For 140mm wide walls, we also have additional midi block options for you to consider, depending on manual handling, thermal and sound reduction requirements.
