Brick and Block Walls

Solid Brick Walls

Bricks ~ these are walling units within a length of 337 5 mm, a width of 225 mm and a height of 112 5 mm. The usual size of bricks in common use is length 215 mm, width 102 5 mm and height 65 mm and like blocks they must be laid in a definite pattern or bond if they are to form a structural wall. Bricks are usually made from clay (BS 3921, BS EN 772-3 and BS EN 772-7) or from sand and lime (BS 187) and are available in a wide variety of strengths, types, textures, colours and special shaped bricks to BS 4729.

Brick Bonding Principles

Bonding ~ an arrangement of bricks in a wall, column or pier laid to a set pattern to maintain an adequate lap.

Purposes of Brick Bonding ~

  3. Create an acceptable appearance.

Simple Bonding Rules ~

  3. Transverse or cross joints continue unbroken across the width of wall unless stopped by a face stretcher.
