- MevaFlex slab formwork
- MEP shoring tower system
- MT 60 shoring tower system
- VarioMax support system
- EuMax Pro prop
MevaDec slab formwork
The lightweight, ergonomic MevaDec is a solution that covers almost every requirement, even for slab thicknesses above 30 cm. It is designed to allow different forming methods to be employed using just one system and identical components:
- Drop-head-beam-panel method
- Primary- and-secondary-beam method
- Panel method
Users simply select the most suitable method for each application. As these methods can also be combined, the number of compensation areas is reduced. MevaDec does not need to adhere to a fixed grid pattern and can be adapted flexibly to suit every building layout, slab thickness, conventionally formed areas and irregular slab edges. The predefined spacing between the props ensures a high degree of safety and enables less material to be stored on the construction site.
The aluminium profiles with a cured powder-coated finish can be cleaned quickly using few resources due to reduced concrete adhesion. The formwork panels with grip openings and ergonomic profiles are easy to handle and can also be safely and effortlessly inserted from below. The standard panel 160/80 cm weighs only 16 kg/m². The new large-size panel 160/160 (with a forming area of 2.56 m²) enables the construction work to proceed even faster. The alkus all-plastic facing with 7-year warranty can be repaired and ensures a consistently high concrete quality. More than 1,000 applications using one facing are not uncommon.
MevaDec is the fastest modular slab formwork system with drop head available on the market *. The time saved for a forming area of 1,000 m² is about 50 hours. When using the drop-head-beam-panel method, the primary beams and panels are lowered by 19 cm using a hammer and can be stripped and used for the next cycle while the slab that has just been formed is supported by the props and continues to harden. Result: rapid construction progress, only a small amount of material stored on-site, simple logistics.
Early stripping is also possible using the primary- and-secondary-beam method. The user selects the facing from the following: shuttering panel 3S, alkus all-plastic facing or other alternatives. The panel method requires only panels and props with prop heads. It is suitable for small building layouts and filler areas in conjunction with simple logistics.
Safe work at heights is ensured by the MEVA MAB working platform or the MevaDec supports for guard-railing posts that can be attached to the panel or the beam and enable guardrailing posts with MEVA safety meshes to be installed.

MevaFlex slab formwork
The conventional formwork offers a high degree of flexibility for large surfaces and slabs with complex layouts. MevaFlex can also be used to support prefabricated slabs. The system is made up of shoring towers or props with forked prop heads, crossbeams and stringers (wood H20 or aluminium) and the freely selectable facing: shuttering panel 3S, alkus all-plastic facing or other alternatives.
The positioning of the beams and props is not predefined. It can be specified during the planning phase to suit the slab thicknesses. This allows for a high degree of flexibility when planning the application. MEP and EuMax props, among others, are suitable for use as supports (pages 8 and 9).
- Simple assembly and use
- Adaptation to varying building layouts and slab thicknesses
- Free selection of the facing
- Stringers and crossbeams are independent of the grid pattern
- Cost-effective and pays for itself after just a few applications.
MEP shoring tower system
Modular shoring towers provide for safety on the construction site. The selection of the best solution is governed by the slab heights and the specific supporting tasks. The MEVA MT 60 and MEP shoring towers provide the optimum support. The use of only a few basic parts and frame types as well as the lack of unnecessary assembly parts enables simple handling and lean logistics.
The strength of the modular MEP shoring tower system lies in its ability to be flexibly adapted to suit every building geometry. With only a few basic parts (props, extensions, frames), it guarantees a high level of stability, simple well-organised storage and rapid material requirements planning. MEP is suitable for supporting slab formwork systems, slab tables, concrete beams or prefabricated components at heights up to 21 metres.
The MEP props are used as individual props or together with reinforcing frames as shoring towers. Ladders and scaffold platforms permit easy access to the slab formwork so that the formwork can be installed or stripped from below even at greater heights. Integrated solutions such as the MEP frame connector or the automatic restraint mechanism on all platforms increase the level of safety. MEP is compatible with all MEVA slab formwork systems and the MT 60 shoring tower. The frames 170 and 220 are designed to suit the system dimensions of the MevaDec slab formwork.

MT 60 shoring tower system
Few individual parts, simple assembly: With only three frame types (100, 75, 50 cm) and the base and head spindles that can be height-adjusted up to 62 cm, any desired tower height up to 18,66 m can be achieved using the MT 60 shoring tower. Due to its high load capacity of 60 kN per leg, the MT 60 is suitable for slab thicknesses up to 71 cm.
The system can be assembled – whether lying down or upright – without tools, bolts or pins. The heaviest individual part weighs no more than 15 kg. The complete tower unit is relocated by crane or on rollers. All parts are hot-dip galvanised.
The system possesses integrated safety features such as the module connections secured with a simple rotational movement, safety access ladders in every segment, scaffold platforms automatically secured in the frame, and all-round fall protection on the working platform. MT 60 and MEP are compatible with each other and with MevaDec, and it is also possible to use the efficient drop-head-beam-panel and primary- and-secondary-beam methods with MevaDec.
light, flexible, cost-efficient
MEVA’s VarioMax is the lightweight and flexible support system for the construction of filigree and in-situ slabs. It significantly reduces the amount of work and the time required on the construction site and consists of just three individual components: telescopic double beams, slide-in beams and props. The slide-in beam can be adjusted to the desired length of every building layout without having to adhere to a fixed grid pattern. Integrated mounting spikes in the beams define the positions and quantity of the props required.
The double and slide-in beams are made of power-coated aluminium. They are light, strong, durable and easy to clean. Depending on the beam combination, slab thicknesses up to 42 cm can be produced. The use of this cost-effective and sustainable system requires less physical effort, less material and shorter walking distances. VarioMax is compatible with the MEVA steel tube props EuMax and EuMax Pro as well as with the shoring tower systems MEP and MT 60 – for simply combinable support options.
The mounting spikes integrated into the beams are simply inserted into the prop openings from above, meaning that forked prop heads are not required. As the prop positions are predefined by the system, 50% fewer props are required, which in turn do not have to be purchased, stored and transported. Furthermore, users enjoy greater freedom of movement due to the low number of props. In the best case, the prop spacing is 2.82 m and only four props are needed for a total stringer length of 8.76 m.
Using the beam clamp H20, VarioMax can also be used as a stringer for the Flex slab formwork. No inconvenient system changes are necessary when combining in-situ and filigree slabs in the same construction: VarioMax suffices. According to the comparative calculation for a 99 m² example floor plan, VarioMax offers great savings potential compared to conventional support methods: 50% fewer props, 54% fewer individual parts, 33% less time required for assembly and disassembly. Last, but not least, VarioMax is 22% lighter. The initially high acquisition costs pay for themselves after just a few uses on the construction site.
