blockwork bonding

• Blocks are made in various thicknesses to suit most wall requirement and are laid in strecther bond
• Thin blocks , used for non-loadbearing partitions , are laid in strecther bond wit each block centred over and under blocks above and below
• At return angles , full blocks bond into the return wall in every other course
• So as not to disturb the full width bonding of blocks at angles , for the sake of stability , a short length of cut block is used as closer and infill block
• Thicker blocks are laid in off centre strecther bond with a three quarter length block at stop ends and sides of openings
• THe off centre strecther bond is acceptable with thicker blocks as it avoids the use of cut blocks to complete the bond at angles
• Concrete blocks walls of specially produced blocks to be used as a fairface finish are bonded at angles to return walls with specially produced quoin blocks for the sake of appearance
• THe L shaped quoin blocks are made to continue the strecther bond around the angle into the return walls
• Quoin blocks are little used for other than fairface work as they are liable to damage in handling and use and add considerably to the cost of materials and albour.
