Brickwork should be set-out using as a ‘unit’ dimension the co- ordinating size of the brick, i.e. one brick length plus one nominal 10mm mortar joint – usually 225mm for standard metric bricks. The mortar joint acts as the ‘buffer zone’ and will be adjusted to suit the actual brick size during construction.
How thick is a Flemish bond wall?
9 inch
The bond can be adapted to suit thicker walls – most houses built in Flemish bond will have walls one brick thick (225mm or 9 inch). Some walls, built in cavity construction, used ‘snapped’ headers to give the appearance of Flemish bond but the external leaf is still a half-brick thick.

What is the strongest bond in bricklaying?
The header Bond in brick is considered to be the strongest and widely used bond in masonry construction. Header means a shorter square span face of the brick which has dimensions 9cm x 9cm. The arrangement is such that it forms the strongest bonding between bricks, making it the strongest bond for bricks.
How do you set out the first course of bricks?
The first brick should be laid at one end and tapped slightly to ‘bed in’. The next brick should be ‘buttered up’ with mortar spread onto each end before being placed to abut the first brick. The trowel should be used to cut away excess mortar that is squeezed out from underneath or in between the bricks.
What is the normal mortar gap between bricks?
3/8″
Mortar joints are typically 3/8″, but can vary from 1/4″ to 1/2″ — we cover this more in our brick sizes article. Bed joints are the horizontal mortar joints, or the bed of mortar that the next brick sits on. Full mortar bedding joints cover the entire top of the masonry unit and are the most common bedding type.
Which brick bond is stronger English or Flemish?
The difference between English bond and Flemish bond are as follows: English bond is much stronger than flemish bond for the walls thicker more than 1½ brick. Flemish bond shows more attractive and pleasing appearance of masonry work.

| No strict supervision and skill is demanded | Requires good workmanship and careful supervision. |
What is standard gap between bricks?
The bricks should be laid around 10mm apart to allow space for your mortar. This will determine the number of bricks per course.
Should mortar be flush with brick?
It is not recommended for exterior building walls because the mortar is not compressed against the block or brick. FLUSH JOINT- Use where the wall is to be plastered or where it is desirable to hide the mortar joints under paint.
What is the maximum thickness of mortar between bricks?
Mortar Thickness
The building code for weight-bearing brick walls calls for mortar to be no more than 3/8 inch thick.
What are the disadvantages of Flemish bond?
The main disadvantage of Flemish bond is that their construction is difficult and it requires greater skill to arrange it properly.
When would you use a Flemish bond?
Flemish bond
This is formed by laying headers and stretchers alternately in each course. The headers of each course are centred on the stretchers of the course below. This bond is strong and often used for walls which are two-bricks thick.
Which bond is strongest in brick?
English Bond
The English brick bond alternates rows of headers with rows of stretchers. This type of wall-building uses more bricks than a stretcher bond, so is rarely used for largescale residential developments, but it is often considered one of the best and strongest brick bond designs around.
Why are there 3 holes in bricks?
Most important, the holes allow the masonry structure to be built more securely. The brick is turned during construction (you won’t see the holes on the finished product) allowing mortar to fall inside. These holes, filled with mortar provide a “keyway,” locking one brick to the next.
Why do bricklayers leave gaps?
Those gaps are called “weep holes” — a building code requirement that drains water out of brick exterior walls. Typically, behind the brick is a 1.5-inch cavity or air space and then the wood structure.
Should you wet bricks before mortar?
So why should you wet bricks before laying them? One of the main problems of having a very porous brick is that there is a greater risk that they might rapidly absorb moisture from the bedding mortar, even quicker should the bricklaying be done on a warm day, causing the mortar to stiffen far too quickly.
How thick should mortar be between bricks?
Mortar joints are typically 3/8″, but can vary from 1/4″ to 1/2″ — we cover this more in our brick sizes article. Bed joints are the horizontal mortar joints, or the bed of mortar that the next brick sits on.
What happens if mortar is too strong?
If mortar is too hard, it will not flex and therefore will tend to crack more so separate from the bricks.
What is the weakest brick bond?
Stretcher bond
The most commonly used bond in the UK, a pattern is made only using stretchers, with the joins on each course centred above and below by half a brick. This type of bonding is not particularly strong. A variation is the raking stretcher bond.
