Wall cracking is one of the most common problems affecting residential and commercial masonry construction across South Africa. While some minor cracking may occur naturally over time, incorrect wall reinforcement often contributes to far more serious structural issues that can become expensive to repair.
This is why proper brickforce reinforcement installation plays such an important role in masonry construction.
Brickforce reinforcement helps strengthen brick walls, improve load distribution, and reduce the risk of cracking caused by movement, settlement, and environmental stress. However, the effectiveness of brickforce depends heavily on installation methods.
In 230mm double walls, specifically, incorrect placement or poor installation practices can reduce reinforcement performance and compromise wall stability.
At Vulcania Reinforcing, quality reinforcing products are manufactured to support stronger, more durable construction projects across South Africa.
Understanding how to install brickforce reinforcement correctly is essential for improving structural performance and preventing avoidable wall cracking.

What Is Brickforce Reinforcement?
Brickforce reinforcement is a welded steel reinforcement product designed specifically for brick and block masonry construction.
It is typically installed horizontally within mortar joints to strengthen walls and improve resistance to:
- cracking
- movement
- vibration
- thermal expansion
- settlement stress
Brickforce reinforcement is widely used in:
- residential housing
- boundary walls
- commercial buildings
- retaining walls
- double wall construction
Proper brickforce reinforcement installation helps improve the structural integrity of masonry walls while reducing long-term maintenance issues.
Why Brickforce Reinforcement Is Important In 230mm Double Walls
230mm double walls are commonly used in South African construction because they provide:
- improved structural strength
- better insulation
- increased durability
- enhanced sound reduction
However, double walls are also vulnerable to movement-related cracking if reinforcement is not installed correctly.
Several factors may contribute to wall cracking, including:
- foundation settlement
- temperature changes
- moisture movement
- Poor mortar application
- inadequate reinforcement
This is why brickforce reinforcement is essential for stabilising wall sections and distributing stress more evenly throughout the structure.
When installed correctly, brickforce reinforcement significantly improves the wall’s ability to resist cracking under normal structural movement.
Common Brickforce Reinforcement Installation Mistakes
One of the biggest causes of wall cracking is incorrect brickforce installation.
Some common mistakes include:
- placing reinforcement unevenly
- insufficient mortar cover
- overlapping incorrectly
- using damaged reinforcement
- skipping reinforcement courses
- poor alignment within mortar joints
These issues reduce the effectiveness of brickforce reinforcement and may create weak points within the wall structure.
Proper installation practices are essential for ensuring reinforcement performs as intended.
Brickforce Reinforcement Should Be Fully Embedded In Mortar
One of the most important installation requirements is that the brickforce reinforcement is fully embedded within the mortar joint.
The reinforcement should never be exposed or too close to the mortar surface.
Insufficient mortar cover may lead to:
- corrosion
- reduced bonding strength
- Weakened reinforcement performance
- premature deterioration
Brickforce reinforcement should be laid evenly into fresh mortar to ensure proper bonding between the steel and masonry components.
Consistent mortar coverage also helps protect the reinforcement against moisture and environmental exposure over time.
Correct Placement Matters
Correct positioning of brickforce reinforcement within the wall is critical.
In most masonry applications, reinforcement is typically placed:
- every third or fourth brick course
- above and below openings
- at stress concentration points
- around windows and doors
Additional reinforcement may also be required in areas exposed to higher structural stress.
Incorrect spacing between reinforcement layers may reduce crack resistance and weaken overall wall stability.
Builders and contractors should always follow engineering specifications and building requirements for the specific project.
Brickforce Reinforcement Overlaps Must Be Correct
Another common mistake involves incorrect overlap lengths between reinforcement sections.
When brickforce reinforcement overlaps are too short, load transfer between sections becomes less effective.
Proper overlap lengths help ensure continuity throughout the wall reinforcement system.
Poor overlap installation may contribute to:
- localised cracking
- weak wall sections
- reduced reinforcement performance
Care should also be taken to ensure reinforcement remains straight and aligned during installation.
Reinforcement Around Openings Is Essential
Wall openings such as:
- windows
- doors
- vents
They are often high-stress areas where cracking commonly develops.
Brickforce reinforcement should be installed carefully around these openings to improve stress distribution and minimise the risk of cracking.
Additional reinforcement may be required above lintels and around corners where movement stresses are concentrated.
This is especially important in double-wall construction, where uneven movement can create additional pressure around openings.

Brickforce Reinforcement Helps Control Shrinkage Cracking
Shrinkage cracking is another common issue affecting masonry walls.
As mortar cures and materials settle, small movements naturally occur within the wall structure. Without adequate reinforcement, these stresses may result in visible cracking.
Brickforce reinforcement helps control these stresses by improving the masonry system’s tensile strength.
This allows the wall to better resist movement without forming significant cracks.
According to guidance from international building authorities, reinforcement plays a critical role in improving crack resistance and structural durability in masonry walls.
Environmental Conditions Also Affect Wall Performance
South African construction projects often face challenging environmental conditions, including:
- temperature fluctuations
- moisture exposure
- soil movement
- seasonal expansion and contraction
These conditions place additional stress on masonry walls over time.
Correctly installed brickforce reinforcement helps improve wall performance under these changing conditions by distributing stress more evenly throughout the structure.
This is particularly important for:
- long wall spans
- boundary walls
- retaining walls
- multi-storey masonry construction
Quality Reinforcing Products Matter
Using high-quality reinforcing products is essential for achieving long-term structural performance.
Low-quality reinforcement products may:
- corrode prematurely
- weaken under stress
- reduce wall durability
- compromise structural integrity
At Vulcania Reinforcing, reinforcing products are manufactured to meet strict quality standards for construction applications across South Africa.
Reliable reinforcement materials help builders improve wall strength while reducing future maintenance and repair costs.
Why Proper Installation Is So Important
Even the highest-quality brickforce reinforcement cannot perform effectively if installed incorrectly.
Proper installation helps:
- reduce wall cracking
- improve structural stability
- strengthen masonry walls
- improve durability
- support load distribution
For contractors, developers, and homeowners, investing in correct reinforcement practices can help prevent expensive repairs later.
Construction professionals should always follow approved engineering guidelines and manufacturer recommendations when installing reinforcement products.
Stronger, More Reliable Construction
Wall cracking remains one of the most common masonry construction challenges in South Africa.
However, many cracking issues can be significantly reduced through correct brickforce reinforcement installation.
In 230mm double walls, proper reinforcement placement, correct mortar coverage, and quality installation practices all play an essential role in improving wall performance and long-term durability.
At Vulcania Reinforcing, quality reinforcing products support stronger, more reliable construction projects across the country.
Strong walls do not depend only on bricks and mortar.
They depend on proper reinforcement, too.
