What is Double Scaffolding?

Double Scaffolding

Double scaffolding, also known as mason’s scaffolding, is a robust and stable construction widely used in stone masonry. Unlike single scaffolding where one end of the scaffold ties into the wall, double scaffolding involves setting up two rows of scaffolding to create a sturdier structure. This method is especially important for stone masonry where the walls cannot be punctured to support putlogs, making traditional single scaffolding impractical.

Structure and Components

Double scaffolding consists of two rows of standards (vertical poles). The first row is positioned about 20 to 30 centimeters from the wall, and the second row is set up about 1 meter from the first, ensuring a strong, stable framework. Horizontal ledgers connect these standards at every level, and cross braces are added for additional stability. Putlogs are then placed with both ends supported by the ledgers, rather than being embedded in the wall, which provides a continuous, unbroken platform across the structure.

Assembly and Application

The primary application of double scaffolding is in stone masonry, where the integrity of the wall must be maintained without drilling holes for putlogs. This scaffolding technique is also used in historical building restorations and other sensitive structures where minimal contact with the wall is crucial. The double scaffold structure ensures workers have safe, stable platforms on which to operate at various heights as the construction progresses.

Safety and Stability

Safety is a paramount concern with double scaffolding, given the often-heavy materials and tools used in stone masonry. The dual-row setup inherently provides a more stable base than single scaffolding, but it also requires careful construction and regular maintenance. Each connection point must be securely fastened, and the entire scaffold should be inspected regularly to ensure its integrity, especially after any adjustments or in adverse weather conditions.

Regulatory Compliance

In the UK, as in many parts of the world, the erection, alteration, and dismantling of scaffolding must comply with stringent safety regulations. According to the Work at Height Regulations 2005, these activities must be performed by competent individuals under the supervision of qualified professionals. Safety features such as guardrails, toe boards, and access ladders must also be included to protect against falls and injuries.


Double scaffolding offers several advantages over other types of scaffolding, especially in terms of stability and safety. The double row of standards provides a firmer base, which is crucial for heavy stone masonry work. Additionally, because the scaffold does not rely on the wall for structural support, it is ideal for use on delicate or historic structures where wall integrity must be preserved.

Economic Considerations

While double scaffolding can be more resource-intensive and expensive to erect than single scaffolding due to the use of more materials and components, its durability and reusability can offer long-term cost benefits. Properly maintained, the components of double scaffolding can be used in multiple projects over many years, offsetting the initial higher cost.

Modern Use and Considerations

Today, double scaffolding remains a preferred method for stone masonry and restoration projects around the world. Its application in preserving historical architecture is particularly valued. Advanced materials and modern engineering techniques have enhanced the functionality and safety of traditional double scaffolding, allowing it to meet the demands of contemporary construction projects without compromising the safety of workers or the integrity of structures.


Double scaffolding is an essential method in the construction industry, particularly for projects involving stone masonry or the restoration of historic buildings. Its robust structure provides the necessary support and stability for heavy-duty work while protecting the integrity of the walls. As with all scaffolding systems, adhering to safety standards and regular inspections are crucial to ensuring a safe working environment. Despite the higher initial setup costs, the benefits of using double scaffolding, particularly in terms of safety and structural integrity, make it a worthwhile investment for suitable projects.
