Mammut XT

Mammut is the high-performance, economical solution for modular large-scale construction. With the new Mammut XT system MEVA is ­setting new standards and thus continuing its success story in the field of 100 kN/m² formwork.

As a convincing solution on construction sites this flexible wall formwork system maximises cost effectiveness.

One system - 3 tying methods

Every construction site is unique, and the formwork requirements vary from project to project. Mammut XT creates an ideal basis for this as the system ensures that you remain flexible and well equipped for every task. Thanks to the smart combination tie hole, it is possible to select between three tying methods with a flick of the wrist. Every panel can be used for both initial and final formwork without additional assembly work. This saves times and simplifies the logistics.

Smart combination Mammut XT tie hole

Using an internal body that can be positioned as required with the XT-combi-lever, the tying method can be changed easily with a flick of the wrist. 

The combination tie hole is integrated into the frame, ensuring that no parts protrude. No installation and removal are required.

Wall thicknesses from 15 to 45 cm

The XT taper tie 20 is available in various lengths for different wall ­thicknesses:

  • 15-25 cm
  • 20-30 cm
  • 35-45 cm

The wall thicknesses are adjusted in 1 cm steps using spacers. The desired wall thickness can be read off the spacers.

Wall thicknesses up to 85 cm

The XT tie rod DW 20 is available in two lengths and can be used for all wall thicknesses.

0–40 cm
0–85 cm

The wall thickness is determined by the length of the plastic tube.

Plastic tubes D23 are available in the corresponding lengths for wall thicknesses of 20, 25, 30 and 35 cm.

Inclined panels

Inclined panels

The clever XT combination tie hole and the XT taper tie enable a panel with an angle of inclination up to 4° to be tied simply and quickly. They can also compensate for angular misalignments up to 4° between adjacent and height-extended panels.

Large-area formwork has never been this flexible and easy to use

  • Multi-function profile 

    made of closed steel profiles with welded-in DW 15 threaded nuts for fast, non-positive attachment of accessories

  • Transport hole 

    to attach the crane sling 60, allowing for fast loading, unloading and relocation of panel stacks

  • Flange screw 

    All auxiliary equipment is connected non-positively using a single part

  • Combination tie hole 

    with a rotating body for single-sided and two-sided tying (three tying methods)

  • Closed profile

    for a high degree of stability and easy ­cleaning – with a hot-dip galvanized surface

  • Bump notch

    allows exact panel positioning without a hammer at the four corners of panels with a width of 125 and 250 cm

  • M assembly lock 

    serves as a panel connection to the surrounding groove

  • alkus all-plastic facing

    The alkus formwork facing does not absorb water, swell or shrink. The rugged, smooth surface guarantees first-class quality of the concrete even after repeated use

Uniform tie hole and joint pattern

The Mammut XT panel dimensions and symmetrical internal tie holes result in a uniform tie hole and joint pattern for the highest architectural-­concrete requirements. This applies to vertical, horizontal or a combination of vertical and horizontal formwork.

With panel heights of 350 cm to 125 cm and panel widths of 250 cm to 25 cm, Mammut XT is readily adaptable to specific layout geometries while ­simultaneously minimising filler areas.

Optimum size matrix

All Mammut XT panels can be combined vertically or horizontally, or height-extended. The ability to freely combine all panels ­vertically or ­horizontally allows for economical width and height extension in ­increments of 25 cm. Filler areas can also be formed quickly and easily using ­compensation panels.


Simple forming of corners

With only three outside corners (side lengths 0, 10 and 15 cm) and two inside corners (side lengths 35 and 40 cm), corners can be formed quickly and easily for all wall thicknesses in 5 cm increments. 

With the Mammut XT internal corners and the 50 and 75 cm wide elements with anchoring points in the frame, you can form 90° corners - optionally on two sides - quickly and economically.

The XT combi-lever

The XT combi-lever is a universal formwork tool fitted with a
karabiner that can be attached anywhere.

Depending on the tying method, the XT combi-lever can be used
in a wide variety of ways, e.g.

  • To set the tying method in the combination tie hole
  • To remove the XT sealing cone from the wall formwork panel


Safety scaffolding mounted directly on formwork

Cost-effective all-in system

Modular safety

This safety system with a working platform is easy to install using a single component – the flange screw. A loadbearing capacity of up to 200 kg/m² guarantees start-to-finish safety throughout the assembly and concreting operations.
