The Two Main Types of Masonry Construction

In construction, masonry is viewed as a preferred mode for many buildings due to its durability, fire resistance, and aesthetic appeal. Here, it’s important to break down the two main types of masonry construction – Veneer and Solid Masonry.

Veneer Masonry

This type of masonry construction uses a single layer of bricks or stones as a cosmetic face to the exterior of the building. The veneer itself does not bear any load other than its own weight and serves primarily for aesthetic purposes. Much of its appeal stems from the creative possibilities it offers in terms of the building’s aesthetic appeal.

Advantages of Veneer Masonry

• Economical – Less labor intensive and consumes less material.
• Variety – Wide array of designs, colors, and textures available.
• Maintenance – Requires less maintenance than solid masonry.

Disadvantages of Veneer Masonry

• Vulnerability – More likely to be impacted by water damage if not properly sealed.
• Repair Difficulty – Harder to repair since the veneer is attached to another structure.

Solid Masonry

Solid masonry is a type of masonry construction where the entire wall is constructed from masonry units (bricks, stones, etc), bound together by mortar. This style of construction is typically more durable than veneer masonry and supports not only its own weight but also the weight of the entire structure.

Advantages of Solid Masonry

• Strength – Can bear significant weight, offering structural integrity.
• Longevity – Known for its durability, can last hundreds of years.
• Sound Insulation – Provides excellent soundproofing.

Disadvantages of Solid Masonry

• Cost – Requires more material and labor, making it more expensive.
• Seasonal Restrictions – Cannot be constructed in freezing conditions.
• Thermal Efficiency – Not as thermally efficient as modern construction techniques.

When deciding between veneer and solid masonry, consideration should be given to factors such as cost, time, aesthetic desires, and the load-bearing requirements of the structure. Referencing well-established sources, like this informative Bob Vila article on masonry, can help guide your decision.
