Perpend Joints, Meaning, Role, and Brickwork Importance
Understanding Perpend Joints
Perpend joints are the vertical mortar joints between the ends of bricks. They run perpendicular to the horizontal bed joints and play a key role in locking bricks together within a course. In brickwork, the correct alignment and staggering of perpend joints is essential for strength, stability, and appearance.
The term perpend comes from perpendicular, reflecting the orientation of these joints in relation to the courses.
Purpose of Perpend Joints
The primary purpose of perpend joints is to bind bricks together horizontally and prevent continuous vertical lines that could weaken the wall. Properly arranged perpend joints help distribute loads and improve the overall integrity of the brickwork.
Key functions of perpend joints include:
-
Locking bricks together within each course.
-
Preventing long vertical joints that reduce strength.
-
Supporting the chosen brick bond pattern.
-
Contributing to the visual rhythm of the brickwork.
Correct perpend joint positioning is fundamental to quality brick construction.
Perpend Joints in Traditional Brickwork
In traditional brickwork, perpend joints are staggered from one course to the next in most brick bonds. This staggering improves structural performance and creates the familiar overlapping appearance of brickwork.
Consistent joint width and full mortar coverage are essential to ensure durability and weather resistance.
Perpend Joints with Brick Slips
When using brick slips, perpend joints are recreated visually during installation and pointing. Brick slips are spaced carefully to ensure vertical joints align correctly with the chosen bond pattern.
Accurate spacing is especially important, as poorly aligned perpend joints can quickly make a brick slip installation look unrealistic. Proper pointing then completes the joint and ties the pattern together visually.
Perpend Joints and Slips from Stock
At Slips from Stock, our brick slips are designed to allow precise spacing and accurate perpend joint alignment. When installed and pointed correctly, the joints help create a convincing brickwork finish that mirrors traditional masonry.
Perpend joints may seem like a small detail, but they are essential to both the performance and appearance of brickwork. Whether using full bricks or brick slips, correct perpend joint layout is key to achieving a strong, balanced, and authentic brick finish.
