Mammut 350

Through its pioneering development in the 1980s of the large-scale, modular, panelised formwork system known as Mammut, MEVA opened up a whole new dimension in formwork efficiency.

 

Delivering the optimum combination of cost-effectiveness and flexibility for industrial construction and civil engineering, the Mammut product family regularly sets new benchmarks in the formwork market. The outstanding feature of the Mammut 350 heavy-duty formwork is its ability to accommodate fresh concrete pressures of up to 100 kN/m² over the entire surface.

Mammut 350 panels and corners

The wide range of Mammut 350 panels ensures prompt and flexible formwork assembly for rapid progress on site. All panels can be set in an upright or horizontal position to ensure easy adaptation to specific layout geometries. The system offers a particularly cost-effective solution on projects with varying storey heights, e.g. residential or commercial buildings with basement car parks. 

  • Panel heights of 350, 300, 250 and 125 cm 
  • Panel widths from 250 to 25 cm
  • 90° inside and outside corners 
  • Hinged corners continuously adjustable between 60 and 180°, with locking device for frequently recurring angles
  • All corner configurations formed with standard corner panels

Mammut 350 saves time

Mammut 350 is easy to set up and allows unlimited pour speeds for heights of up to 4 m. Large formats, with a maximum of 8.75 m² per panel, ensure rapid progress of work on site. Storey heights of up to 350 cm can be cast with a single panel, with no need for vertical extension.

Top performance

Accommodating maximum permissible fresh concrete pressures of 100 kN/m², Mammut 350 offers outstandlingly short pour times due to the unlimited speeds possible for concrete lifts of up to 4 m. Panel widths of 100 cm or more require the use of DW 20 tie rods.

  • Only two ties are needed for heights up to 3 m and three for heights up to 3.50 m

Ideal for fair-faced concrete

Mammut 350 offers the ideal solution in meeting the diverse requirements placed on fair-faced concrete. The visual impact achieved by the alkus all-plastic facing, in conjunction with the symmetrical tie and joint pattern, ensures that – whatever the specified grade of fair-faced concrete – the system significantly enhances the overall architectural appeal of any project.
