PERI: An Overview of Popular Formwork Systems and Their Applications

The choice of formwork directly affects the pace of construction, the stability of structures, and the final result after formwork removal. That is why contractors often compare systems from different manufacturers: what are the differences between brands, what is the Equipment lifespan, how does it perform in real-world conditions, and why do some solutions last for years while others last only a few cycles.

In this series of articles, we will examine the global formwork brands that set industry standards, explain how their systems work, highlight the key differences between them, and discuss why these manufacturers form the backbone of Budhub’s professional formwork fleet.

Let’s start with PERI—one of the world’s leading formwork manufacturers, whose systems have been used for many years in residential, industrial, and infrastructure construction in Ukraine.

PERI: The world’s largest formwork manufacturer

PERI is one of the world’s largest manufacturers of formwork and scaffolding, operating in over 60 countries and maintaining a network of factories across Europe, Asia, and North America. The brand has been growing since the late 1960s and is now considered a technological leader in concrete construction.

In practice, PERI is recognized for its consistent geometry, precise performance, and ability to maintain a steady pace of installation on projects of all sizes—from residential to industrial and infrastructure.

So, here’s an overview of PERI systems, which have become the standard in monolithic construction.

The most well-known Peri formwork systems

The PERI product line is designed to cover as many aspects of monolithic construction as possible—from private foundations to complex structures with non-standard geometries. Let’s take a closer look at them.

Where PERI DOMINO formwork systems are used: single-family homes, low-rise buildings, renovation projects, and sites with limited access for heavy equipment.

PERI MAXIMO

PERI MAXIMO is a frame formwork system that eliminates some of the routine tasks: formwork is installed on only one side, so formwork assembly is faster and the concrete surface remains clean. This is important where there are strict finish requirements or a tight schedule.

Features of the PERI MAXIMO formwork system:

• Single-sided tie rod system. The main feature of this system is that the tie rods are installed on one side of the wall. This eliminates half of the routine tasks and significantly speeds up installation, especially at heights or in confined spaces.
• Central placement of tie rods. The through-bolts are positioned in the center of the formwork panel, ensuring that the load is distributed evenly and the surface remains clean after the formwork is removed.
• Sturdy steel frame. MAXIMO frames feature reinforced rigidity, ensuring precise geometry when working with high walls, heavy loads, and fast pouring speeds.
• Logical module grid. The panels come in convenient standard sizes (2.70 x 2.40 m, 2.70 x 1.20 m, 3.30 x 2.40 m) and custom formats, allowing for the rapid assembly of large surfaces and a reduction in the number of joints.
• Standardized safety components. The system includes standard attachment points for scaffolding, guardrails, and platforms, which simplifies the organization of work at height.
• Optimized assembly. Special locks and central connectors allow you to quickly align panels at right angles, compensate for height differences, and work precisely with extension pieces.

Where PERI MAXIMO formwork systems are used: residential and commercial buildings with a large number of wall structures, projects requiring a smooth concrete finish, and confined workspaces.

PERI VARIO GT 24

PERI VARIO GT 24 is a versatile modular beam-and-girder formwork system for walls, columns, and slab formwork. It is used when the geometry exceeds the capabilities of standard formwork panels: radii, variable thickness, high walls, and critical loads. Thanks to the GT24 beams, the system adapts to any shape without compromising strength.

Features of the PERI VARIO GT 24 formwork system:

• GT 24 Beam. The system is based on a 24-cm-high timber beam that serves as a load-bearing element. It provides high rigidity, allows for wider stud spacing, and can handle high concrete pressure.
• Custom layout. The panels do not have a fixed frame—the system is assembled on-site using beams, posts, and plywood. This ensures maximum design flexibility: curves, slopes, non-standard angles, and variable wall thicknesses.
• Reinforced columns and beams. Steel flanges and vertical sections can withstand heavy loads and allow for construction at significant heights without compromising structural rigidity.
• Any panel format. Thanks to the VARIO GT 24’s modular design, you can create panels of almost any size—from small inserts to large surfaces for crane installation.
• Choosing plywood. The system allows for the use of various types of plywood (birch, composite, Latvian plywood, and filler plywood), which is important for high-volume production or when a clean surface is required.
• Designed for heavy-duty applications. The VARIO GT 24 is used in situations where the pressure of the concrete mix exceeds the capacity of standard frame systems—in massive walls, core walls, and industrial structures.

Applications for the PERI VARIO GT 24 formwork system: public buildings, structures with complex architecture, and infrastructure projects.

PERI SKYDECK / MULTIFLEX

SKYDECK and MULTIFLEX are two separate PERI systems for floor slabs, but in practice they are often used together because they complement each other. SKYDECK enables quick installation and early formwork removal on standard slabs, while MULTIFLEX handles complex geometries, projections, and variable thicknesses.

Together, these systems cover virtually all flooring needs in residential, commercial, and industrial buildings, so combining them allows for precise planning of the work schedule and eliminates the need to keep excess equipment in stock.
