Classification, Uses and Construction Details
Brick masonry is widely used in buildings for walls, partitions, façades, boundary walls, and architectural features. Its appearance and construction depend not only on the bricks and mortar selected but also on the way individual bricks are arranged and connected.
A brick bond is the arrangement of bricks in successive courses to create a coherent masonry assembly. Different bonds produce different surface patterns, joint arrangements, and methods of connecting bricks across the thickness of a wall.
For architects and construction professionals, understanding brick bonds is important when preparing elevations, masonry plans, construction details, specifications, and site instructions.
This guide explains ten traditional types of bonds in brick masonry, their characteristics, applications, advantages, limitations, and important construction considerations.
What Is a Bond in Brick Masonry?
A brick bond is the systematic arrangement of bricks in a wall, with the units positioned to create the intended pattern and, where applicable, interlock the masonry through its thickness. Proper bonding helps distribute loads, limits continuous vertical joints, and contributes to the stability and durability of the wall.
The term bond can refer to the visible pattern on a wall face or to the arrangement that connects different parts of the masonry assembly. These are related but not identical concepts: a decorative pattern alone does not guarantee adequate structural bonding.
Why Is Brick Bonding Important?
Brick bonding serves several purposes in masonry construction.
- Interlocking: Appropriate arrangements connect bricks in successive courses and, in traditional solid masonry, can tie the wall through its thickness.
- Load transfer: A properly designed and constructed wall transfers loads through its masonry units and mortar joints.
- Joint arrangement: Staggered joints avoid long, uninterrupted vertical joint lines in many conventional bonds.
- Appearance: Bond patterns create distinctive rhythms, textures, and proportions on exposed brick surfaces.
- Workmanship: A defined bond helps masons establish corners, junctions, openings, and successive courses consistently.
- Material planning: Bond selection affects brick cutting, closures, mortar use, and the amount of waste generated.
Bonding must be coordinated with wall thickness, brick dimensions, mortar, structural requirements, and the construction system. No bond pattern should be selected on appearance alone when structural performance is involved.

Basic Terminology Used in Brick Bonding
Understanding the following terms makes bond diagrams and construction drawings easier to interpret.
1. Stretcher
The long face of a brick visible in the wall elevation when the brick is laid with its length parallel to the wall face.
2. Header
The short end face of a brick visible in the wall elevation when its length extends into the wall.
3. Queen closer
A brick cut longitudinally into two equal-width portions. It is commonly used next to a quoin header in traditional bond arrangements to help maintain the required lap.
4. Quoin
The external corner of a wall, or the masonry units forming that corner.
5. Bed joint and perpend
A bed joint is the horizontal mortar joint between courses. A perpend is a vertical joint between adjacent bricks.

10 Types of Bonds in Brick Masonry
Brick bonds are commonly classified according to the orientation of bricks, their arrangement within each course, and the relationship between successive courses. The following are ten traditional types found in building-construction references. Terminology and details may vary by region and textbook.
1. Stretcher Bond
Definition: Stretcher bond is a brick arrangement in which the long faces of the bricks are visible in the wall elevation. Each course is generally offset from the course below to create a staggered joint pattern.
Characteristics
- Uses stretchers throughout the principal visible arrangement.
- Produces continuous horizontal lines and a regular running pattern.
- Can be laid with relatively little cutting on straightforward wall lengths.
- Does not, by itself, provide header connections through a thick solid wall.
Applications
- Half-brick-thick partitions where appropriate to the design.
- The individual leaves of cavity walls.
- Brick veneer and facing systems designed with suitable ties or supports.
- Selected non-load-bearing wall applications.
Advantages: Simple setting-out, regular appearance, and efficient construction on uncomplicated layouts.
Limitations: A stretcher pattern should not be mistaken for a structural connection through the thickness of a solid wall. Wall stability, lateral support, ties, reinforcement, and loading must be considered separately.
2. Header Bond
Definition: Header bond is an arrangement in which the short faces of the bricks are visible in successive courses.
Characteristics
- Bricks are oriented with their lengths extending into the wall.
- The layout uses appropriate lap and closure details to maintain the intended pattern.
- The short-face appearance gives the wall a compact, repetitive texture.
Applications
- Certain curved masonry walls.
- Traditional solid masonry arrangements and selected thick-wall construction.
- Specific details where the header orientation is appropriate to the geometry.
Advantages: Can provide transverse interlocking in traditional solid masonry when correctly detailed and constructed.
Limitations: Curvature, brick dimensions, cutting, and the intended wall thickness affect the setting-out. Its suitability for a load-bearing wall must be established through structural design rather than assumed from the bond name.
3. English Bond
Definition: English bond consists of alternate courses of headers and stretchers. One course contains headers across the face; the next contains stretchers, and the pattern repeats.
Characteristics
- Header and stretcher courses alternate vertically.
- A regular arrangement of closures is used at corners where required.
- The pattern can connect the masonry through its thickness in traditional solid-wall construction.
- The exposed elevation typically shows alternating horizontal bands.
Applications
- Traditional solid brick masonry.
- Selected load-bearing masonry walls when supported by structural design.
- Traditional and heritage-inspired architecture.
Advantages: Provides a clear, systematic construction sequence and can achieve effective bonding through the wall thickness.
Limitations: The visible pattern is relatively banded, and the required closures and corner arrangements need careful setting-out. Actual strength depends on the bricks, mortar, dimensions, workmanship, support conditions, and design.
4. Flemish Bond
Definition: Flemish bond is an arrangement in which headers and stretchers alternate within each course. The headers are positioned to overlap the stretchers in adjacent courses.
Characteristics
- Alternating header-and-stretcher pattern within each course.
- A more finely articulated visual texture than English bond.
- Requires accurate setting-out and appropriate closures at corners.
- May be executed as double Flemish bond or, in suitable traditional constructions, single Flemish bond.
Double Flemish bond: The Flemish pattern is visible on both faces of the wall.
Single Flemish bond: Flemish bonding is used on the exposed face, while the backing is arranged using a different bond, commonly an English-bond arrangement in traditional examples.
Applications
- Exposed brick façades.
- Traditional residential and institutional buildings.
- Architectural projects where brick texture is a major design feature.
Advantages: Offers an attractive, repetitive pattern and can provide transverse bonding when designed for a suitable solid-wall construction.
Limitations: Accurate brick selection, corner detailing, and workmanship are important. It is not automatically structurally superior or inferior to English bond in every wall configuration.
5. Garden-Wall Bond
Definition: Garden-wall bond is a family of arrangements in which headers occur less frequently than in conventional English or Flemish bond. The precise pattern depends on the type.
Common variations
- English garden-wall bond: A header course occurs after several stretcher courses.
- Flemish garden-wall bond: Each course contains groups of stretchers separated by headers.
Applications
- Selected garden and boundary walls.
- Traditional landscape walls.
- Exposed masonry where a predominantly horizontal pattern is desired.
Advantages: Creates a less repetitive header pattern and can simplify the appearance of long wall elevations.
Limitations: The exact arrangement must be identified on drawings. A garden-wall bond should not be presumed suitable for retaining soil, resisting wind, or supporting building loads without appropriate design.
6. Raking Bond
Definition: Raking bond uses bricks arranged diagonally within a masonry pattern. Diagonal arrangements may occur in selected thick-wall construction or in decorative panels.
Common forms
- Diagonal bond.
- Herringbone arrangement.
- Other regional or decorative diagonal patterns.
Applications
- Selected thick masonry where the design calls for a raking arrangement.
- Decorative brick panels.
- Architectural features requiring diagonal geometry.
Advantages: Introduces visual direction and can create distinctive geometric patterns.
Limitations: Cutting, setting-out, and coordination at the panel boundaries can be more demanding. A decorative diagonal pattern is not, on its own, proof of adequate structural bonding.
7. Dutch Bond
Definition: Dutch bond is a traditional modification of English bond. Its exact arrangement varies among construction references, but it is generally intended to improve the bonding or appearance of selected corner and course arrangements.
Characteristics
- Incorporates features of English-bond construction.
- Uses modified brick placement near corners or in selected courses.
- Requires a clearly defined layout to avoid confusion with other modified bonds.
Applications: Traditional masonry walls where the specified Dutch-bond arrangement is appropriate.
Advantages: Can improve the continuity of the bond pattern at particular details.
Limitations: The term is not always used consistently across regions. Drawings should show the actual course arrangement rather than relying on the name alone.
8. Brick-on-Edge Bond
Definition: In brick-on-edge work, bricks are laid on an edge rather than on their broad bed face, creating a characteristic narrow or linear pattern.
Applications
- Selected garden and boundary-wall details.
- Edging and decorative masonry.
- Certain traditional low-wall arrangements.
Advantages: Creates a distinctive architectural finish and can reduce material use in some applications.
Limitations: Orientation affects the bearing area, stability, and durability of the assembly. It should not be treated as an interchangeable substitute for conventional load-bearing brickwork.
9. English Cross Bond
Definition: English cross bond is a variation of English bonding in which the arrangement of successive stretcher courses produces a cross-like relationship in the visible joint pattern.
Characteristics
- Alternating header and stretcher courses.
- A modified arrangement of joints in the stretcher courses.
- A more articulated elevation than a simple alternating-band pattern.
Applications: Selected traditional exposed brickwork and architectural masonry where the pattern is specified.
Advantages: Creates visual variation while retaining the general logic of alternate header and stretcher courses.
Limitations: The name can be interpreted differently in teaching and regional references. Course-by-course drawings should be provided when this specific pattern is required.
10. Facing Bond
Definition: Facing bond is a traditional arrangement used to coordinate the exposed facing and the backing of a wall, particularly where their brick dimensions or course heights differ.
Characteristics
- The facing and backing may use different arrangements.
- Selected header courses or other specified connections may be used to tie the components together.
- The precise detail depends on the wall build-up and construction system.
Applications: Traditional masonry construction where the facing and backing require a coordinated bond arrangement.
Advantages: Can help coordinate different masonry layers when properly designed.
Limitations: The term does not automatically mean that a modern brick veneer is structurally tied to its backing. Contemporary cavity walls and veneers generally require their own specified support and tie systems.
Quick Comparison of Brick Bonds
| Bond type | Basic arrangement | Visual character | Typical application |
|---|---|---|---|
| Stretcher | Stretcher courses with staggered joints | Horizontal running pattern | Thin wall leaves and veneer systems |
| Header | Header courses | Compact repeated pattern | Selected traditional solid or curved masonry |
| English | Alternate header and stretcher courses | Horizontal bands | Traditional solid masonry |
| Flemish | Alternating headers and stretchers within each course | Repeated checker-like pattern | Exposed traditional brickwork |
| Garden-wall | Headers spaced among groups of stretchers | Predominantly horizontal | Selected garden and boundary walls |
| Raking | Diagonal brick arrangement | Diagonal geometry | Selected masonry or decorative panels |
| Dutch | Modified English-bond arrangement | Traditional modified pattern | Specific traditional details |
| Brick-on-edge | Bricks placed on edge | Narrow linear pattern | Selected edging and low-wall details |
| English cross | Modified English-bond joint arrangement | Cross-like joint rhythm | Traditional exposed masonry |
| Facing | Coordinated facing and backing arrangement | Depends on facing pattern | Traditional multi-layer masonry |
Important: This table describes general patterns and typical contexts, not a structural design specification. Some terms have regional variations, and the suitability of any bond depends on the complete wall assembly.
Difference Between English Bond and Flemish Bond
English bond and Flemish bond are two important traditional patterns in brick masonry. The principal difference is how headers and stretchers are arranged in each course.
| Feature | English bond | Flemish bond |
|---|---|---|
| Course arrangement | Alternating header and stretcher courses | Headers and stretchers alternate within each course |
| Appearance | Strong horizontal bands | Repeating header-stretcher rhythm |
| Setting-out | Alternating course types | More detailed repeated arrangement in each course |
| Corner details | Closers and appropriate course layout | Closers and careful header positioning |
| Design emphasis | Traditional masonry arrangement | Traditional masonry with a more articulated face |
| Structural suitability | Depends on the complete wall design | Depends on the complete wall design |
Neither bond should be selected solely because it is traditionally described as stronger. Structural suitability depends on wall thickness, materials, loading, workmanship, restraint, and applicable design requirements.

How to Select a Suitable Brick Bond
The choice of bond should be made early enough to coordinate architectural elevations, wall thickness, corners, openings, and construction details.
1. Identify the wall construction
Determine whether the wall is a thin partition, solid masonry wall, cavity wall, or brick veneer. A pattern appropriate for one construction system may be unsuitable for another.
2. Establish structural requirements
For load-bearing masonry, obtain the required wall thickness, material properties, support conditions, and loading from the structural design. The bond pattern is only one part of the solution.
3. Coordinate architectural appearance
Consider the scale of the brick, the rhythm of horizontal and vertical joints, the desired façade texture, and how the pattern meets windows, doors, corners, and parapets.
4. Review setting-out and cutting
Check how the bond will work at returns, wall junctions, piers, and changes in wall thickness. A pattern that looks simple on an uninterrupted elevation may require substantial cutting at corners.
5. Specify materials and workmanship
Coordinate brick dimensions, mortar specification, joint profiles, tolerances, and any required ties or reinforcement with the project documentation.
6. Verify applicable standards
In India, IS 2212:1991, Brick Works — Code of Practice, addresses general brickwork construction, while IS 1905:1987 addresses the structural use of unreinforced masonry. Confirm the applicable editions, amendments, and project requirements before specifying or constructing the wall.

Construction Principles for Good Brick Bonding
A well-executed bond requires more than following a repeating visual pattern.
- Maintain the specified lap: Arrange successive courses so the intended overlap is maintained.
- Avoid unintended continuous joints: Check the course layout, especially at corners and junctions.
- Detail corners before laying: Establish the quoin arrangement and required closures in advance.
- Fill mortar joints as specified: Incomplete joints can affect the integrity and weather resistance of the masonry.
- Check alignment and level: Use suitable setting-out and checking methods to maintain line, level, and plumb.
- Coordinate openings: Plan the bond around doors, windows, lintels, and other interruptions.
- Provide the specified support and ties: Thin wall leaves and veneer systems may depend on designed supports and mechanical connections.
- Follow the project specification: Brick preparation, mortar proportions, curing, and workmanship requirements depend on the brick type, mortar system, climate, and applicable code.
The applicable construction standard and project specification should govern these requirements.

Common Mistakes in Brick Bonding
1. Confusing the visible pattern with structural bonding
A wall may look correctly bonded on its exposed face without having an adequate connection through its thickness. Review the wall section and plan, not just the elevation.
2. Ignoring corners and junctions
A bond pattern can become discontinuous where walls meet. Show the corner arrangement and check how successive courses intersect.
3. Using stretcher bond without considering wall stability
Stretcher bond is common in thin wall leaves, but it does not automatically provide transverse bonding in a thick solid wall. Confirm the support and connection system.
4. Assuming a traditional bond guarantees structural strength
Bond names do not replace engineering calculations or design requirements. Materials, workmanship, wall geometry, and loading remain important.
5. Failing to coordinate the bond with openings
Window reveals, door jambs, lintels, and changes in wall thickness can disrupt the intended pattern unless they are considered during setting-out.
6. Copying a diagram without checking brick dimensions
A diagram based on a different brick size or mortar-joint thickness may not work at the actual project dimensions. Prepare a setting-out detail using the specified units.
Practical Architectural Applications
Brick bonds influence both the construction process and the architectural character of a building.
- Residential architecture: Stretcher bond is common in thin wall leaves and facing systems; English or Flemish bond may be selected for traditional solid masonry where appropriate.
- Institutional buildings: Exposed brick patterns can establish scale, rhythm, and material identity across large elevations.
- Landscape architecture: Garden-wall and selected brick-on-edge arrangements can contribute to boundary walls, edging, and landscape features.
- Heritage architecture: Traditional bond patterns can be important in understanding historic workmanship and matching repairs.
- Contemporary façades: Running patterns, recessed joints, and other brick arrangements can be used as architectural finishes, provided the support and attachment system is designed appropriately.
These examples are applications of the patterns, not claims that any particular building uses a specific bond without verified project documentation.
Advantages of Brick Bonding
- Helps establish an organized masonry layout.
- Can improve interlocking when the selected arrangement connects the masonry appropriately.
- Creates architectural variation through the pattern of bricks and joints.
- Supports systematic setting-out at corners and junctions.
- Allows the architect to coordinate material texture with façade proportions.
- Can reduce unnecessary cutting when the pattern is planned around the specified brick dimensions.
Limitations and Challenges
- Complex patterns can require additional setting-out and cutting.
- Poorly coordinated joints may produce an inconsistent appearance.
- A visible pattern cannot compensate for inadequate wall design.
- Brick dimensions and mortar joints affect the practical feasibility of the pattern.
- Traditional solid-wall bond details may not be directly transferable to modern cavity-wall or veneer systems.
- Structural and weatherproofing requirements may dictate details that are not obvious from the elevation alone.
Frequently Asked Questions
What are the main types of bonds in brick masonry?
The main traditional types include stretcher bond, header bond, English bond, Flemish bond, garden-wall bond, raking bond, Dutch bond, brick-on-edge bond, English cross bond, and facing bond. Their arrangements and applications differ, and some names vary between regional construction references.
Which brick bond is most commonly used?
Stretcher bond is common in thin wall leaves and brick veneer systems. English and Flemish bonds are familiar traditional patterns in solid brick masonry. The appropriate choice depends on the wall construction, structural requirements, and architectural intent.
What is the difference between English bond and Flemish bond?
English bond alternates complete header and stretcher courses. Flemish bond alternates headers and stretchers within each course. Both require appropriate corner details, and neither is universally preferable for every structural condition.
Why are closers used in brick masonry?
Closers are used to help maintain the intended bond and lap at corners and other locations. A queen closer is a brick split lengthwise into two equal-width pieces and is commonly used next to a quoin header in traditional arrangements.
Can stretcher bond be used for load-bearing walls?
Stretcher bond alone does not establish adequate structural bonding through the thickness of a solid wall. Its use in load-bearing construction depends on the complete wall system, including its thickness, support, ties or reinforcement where required, and structural design.
What is a garden-wall bond?
Garden-wall bond refers to arrangements in which headers occur less frequently than in conventional English or Flemish bond. English garden-wall bond typically uses several stretcher courses between header courses; Flemish garden-wall bond distributes headers within each course.
Is Flemish bond stronger than English bond?
Neither should be described as universally stronger. Structural performance depends on the complete masonry design, including brick and mortar properties, wall thickness, workmanship, support conditions, and applied loads.
What is the purpose of a brick bond diagram?
A bond diagram shows the arrangement of bricks in successive courses, helping the reader understand orientation, lap, closures, and the resulting wall pattern. For construction, plans and corner details should supplement the elevation.
Are brick bonds the same as mortar joints?
No. A brick bond describes the arrangement of bricks. Mortar joints are the horizontal and vertical joints between units. Joint dimensions and workmanship contribute to the performance and appearance of the masonry assembly.
Which Indian standards are relevant to brick masonry?
IS 2212:1991 addresses brickwork construction, and IS 1905:1987 addresses the structural use of unreinforced masonry. Applicable editions, amendments, other relevant standards, and project-specific requirements should be verified before construction.

Conclusion
Brick bonds are an essential part of architectural detailing and masonry construction. Stretcher and header bonds illustrate the basic orientation of bricks, while English and Flemish bonds demonstrate two major traditional arrangements for solid masonry. Garden-wall, raking, Dutch, brick-on-edge, English cross, and facing bonds serve more specialized construction or architectural purposes.
The correct choice depends on the intended wall system, structural requirements, appearance, brick dimensions, and construction details. For architectural drawings, the bond should be coordinated across elevations, plans, sections, corners, and openings rather than represented only by a decorative surface pattern.
For reliable construction, consult the applicable masonry standards and project specifications, and obtain structural review wherever the wall is load-bearing or requires engineered support.
