Diagrams to PDF to create and print a PDF (at 100% scale). Fold and use to mark out your gauge rod or profile, 3 courses at a time.
Every 3rd course is red, so you can check progress occasionally to make sure you're not creeping up or down as you mark out.
This Gauge Chart uses adjusted Bed Joint sizes to suit Total Height and Courses as calculated above.
Brick Bond with End Closure Cuts and All Cutting + Fit Options
Enter Wall Length, and if there's closures, select
Adjust Perps to Fit Full Bricks to see perp joint sizes that will fit with full bricks and halves.
Running Bond -
mm Perps:
Possible Opening Widths that suit Bond:
Check your bond (with 10 mm perps) to see what you'll get at the end of the 1st course? (set out)
Measure from the end of the last full stretcher you've laid to the end of the wall, and enter into Last Gap to calculate the bond fit at the end.
If you get cuts, but are within plus or minus 10 mm of fitting full bricks (or a half), it will tell you how much to open or close to remove the cuts and get full bricks.
If measuring total wall length, add 10 to actual Wall Length then enter into Last Gap. (allows for first perp)
A
Course is a single row of bricks.
Gauge is the vertical spacing of each course.
Bond (in this context) is the horizontal spacing of bricks in each course.
Bed Joints are the horizontal mortar joints, and determine
Gauge. They are normally 10 mm, but can sometimes be slightly adjusted to fit whole courses into a given height.
Perp Joints are the perpendicular mortar joints, and determine
Bond. They are normally 10 mm, but can sometimes be slightly adjusted to fit whole bricks into a given length.
A
Stretcher is a full length brick.
A
Bat is a
Half Brick. Half bricks are the
Width of the brick, and are calculated at 1/2 Stretcher Length - 1/2 standard 10 mm joint width.
This is a general standard, and means when you have a returning corner, the
END of the brick becomes the half at the corner.
Also piers and header bond will work correctly, with 10 mm perps.
If you adjust the perp sizes slightly to fit a given wall or panel length, the half brick will stay the same as for a standard 10 mm joint.
This will slightly alter the joint widths at the wall end halves or corners.
A
Closure is a cut brick to fit the last gap/s where a Stretcher will not fit.
If a closure is less then 40 mm longer than a bat, the perp joints at closure and bat would be too close together, so an extra closure is added to increase the horizontal separation of the perps.
