In monolithic construction, it is important to select the right formwork system based on the site conditions. While telescopic props work effectively at heights up to 5–5.5 m, they are no longer used for floor slabs 6–7 m high—at such heights in Ukraine, a shoring system is used.
It plays a key role in the floor system—it keeps the system within its design parameters, ensures safe working conditions, and provides structural stability at great heights.
That’s why it’s important to understand what a shoring system is, how it works, and what types of systems are available—we cover all of this in detail in our article.
What is a shoring system?
The shoring system is a type of construction scaffolding used during the pouring of massive floor slabs at significant heights. It is used in situations where the use of standard telescopic props is impractical or technically impossible.
The shoring system serves as a temporary support: it does not come into direct contact with the concrete, but supports the entire formwork system during pouring, withstands significant loads from the concrete, rebar, and the weight of the equipment itself, and evenly transfers these loads to the foundation.
The main difference between a shoring system and telescopic props lies in its design: it consists of vertical frames or posts connected by horizontal and diagonal elements. As a result, the system forms a spatial structure capable of withstanding significant loads without deformation. It supports the Slab formwork and ensures the safety of personnel during installation, reinforcement, or concrete pouring.
When is it appropriate to use a shoring system?
Let’s consider some typical situations where a structure requires the use of a shoring system:
1. Floor-to-floor height exceeding 6 m
. Given that shoring props taller than 5.5 m are rare on the Ukrainian market, it is advisable to use a shoring system for floors of this height. It forms a stable tower structure that withstands the load from concrete, rebar, and the formwork’s own weight without the risk of deformation.
2. Complex structural
geometry: Sloped or domed ceilings, beams, and parking ramps—all these elements require a customized approach. The modular structure of the scaffolding allows each support to be set at a different height and creates a precise project plane.
3. Reinforcement and Masonry Work on High Walls
At heights of 4 meters and above, it is necessary to ensure safe access for personnel to the work site, so a shoring system is used to create work platforms, stair towers, and platforms capable of supporting the weight of a person, tools, and rebar.
4. Height Adjustment for Uneven Terrain
The shoring system can be adjusted for height individually in each section, allowing for leveling even on surfaces with significant unevenness.
Advanced technical applications in which a shoring system is also frequently used:
Non-standard slab height or thickness exceeding 300 mm
Heavy floor slabs place increased stress on the supports, so the system must ensure even weight distribution without the risk of sagging. If the floor slab is not very thick, it is advisable to construct such structures using telescopic props, thereby reducing the spacing between supports. However, in cases where the props do not reach the design height, or the load is combined with a significant height, a shoring system is used, which provides a sufficient safety margin even for slabs with a thickness of 0.5–1 m.
Elevation and organization of access to work levels
For work at significant heights, the shoring system can be supplemented with stair towers. Incidentally, in such cases, Budhub uses Layher systems as auxiliary equipment when working with frame systems, specifically the Doka Staxo 100. Stair towers ensure the safe ascent of personnel to working levels and convenient access to assembly and concrete pouring areas.
Types of shoring systems
In terms of design, shoring systems can vary in terms of assembly methods and operating principles.
In monolithic construction, two main types are most commonly used: frame scaffolding and modular (rosette) scaffolding. Both options serve the same purpose—creating a system capable of withstanding heavy loads during concrete pouring—but have their own installation characteristics, adjustment capabilities, and areas of application.
To better understand the differences and characteristics, let’s take a look at the features of each system.
Frame scaffolding
Frame shoring consists of metal frames connected by horizontal members and diagonal braces. A single tower is formed from two flat frames, creating four uprights. This design provides structural rigidity and allows the scaffold to withstand heavy loads without deformation.
The frames have a fixed width and come in three standard heights: 0.9 m, 1.2 m, and 1.8 m.
The use of diagonal plumbing struts of varying lengths (from 1.0 to 3.0 m in 0.5 m increments) allows for adjusting the distance between frames and adapting the tower to design loads.
Spindles are installed at the top and bottom of the structure to ensure precise height adjustment. Most systems have spindle extension lengths of up to 350 mm, while reinforced versions extend up to 500 mm, allowing for precise formwork alignment on uneven surfaces and compensation for elevation differences.
Frame scaffolding can be assembled manually piece by piece or moved by crane in pre-assembled units, which significantly speeds up the work process between work phases.
The system consists of only a few components, so it is easy to assemble even without a detailed design—using standard solutions.
- Examples of the system: Doka Staxo 40 / Doka Staxo 100.
Modular (rosette) scaffolding
Modular or rosette scaffolding consists of individual uprights, horizontal members, and diagonal braces that are connected to one another using rosette joints (from the word “rosette”—a round disc with holes).
Each tower is made up of four separate posts, allowing for structures of any height and configuration to be built.
This type of scaffolding is highly versatile—it can be adapted to sloped, domed, or uneven surfaces.
The modular system is capable of operating at heights of up to 40 meters and supporting loads of up to 4–6 tons per tower. Thanks to its modular connections, precise geometry is ensured, and the structure itself remains stable even under heavy loads.
This type of scaffolding is often used to construct stair towers, work platforms, or decking for reinforcing tall monolithic walls. Individual components of the system can be combined with frame scaffolding, allowing the equipment to be used effectively for various tasks at a single construction site.
- Examples of systems: PERI UP Rosett, Layher Allround.
Frame and modular systems address different needs, complementing one another: frame scaffolding is used where high load-bearing capacity, quick assembly, and the ability to move large amounts of equipment by crane are essential; Modular (rosette) scaffolding, thanks to its flexibility, allows for work on complex geometries, sloped surfaces, and different elevation levels.
Together, they cover the entire spectrum of needs in monolithic construction: from standard residential buildings to complex engineering structures.
Shoring systems available in Budhub’s equipment fleet
Every structure has its own structural complexity, height, and load requirements. For some, lightweight frame towers are sufficient; for others, a system capable of supporting tens of tons of concrete at significant heights is required.
