VARIOKIT, the adjustable formwork for tunnel projects supplied by PERI

Infrastructure for Tunnelling

Construct with confidence from one end to the other

From innovative temporary works to support shaft construction to accommodating various tunnel geometries, our engineering team has a diverse level of expertise in tunnelling. With the flexible design of our VARIOKIT components, we can provide a solution for any cross-section and casting method.

How we can support you

Cost-effective construction

With rentable VARIOKIT components and system integration, we can design cost-effective tunnel formwork carriages to deliver project-specific requirements and accommodate site limitations. Requirements such as drive-through openings for trucks or single-sided wall formwork are easily fulfilled with fully customisable solutions like ours.

Our tunnelling solutions are also compatible with hydraulic technology if your project requires it, which helps to speed up operations like lifting, lowering and moving. Shorter shuttering and striking times are also possible, helping to maintain planned sequences, deadlines, and costs.

Approaching complexity with collaboration

The complex nature of tunnelling projects means working together is vital to ensure success and smooth delivery. Our engineering experts and experienced project managers support you with detailed planning of concreting sections, sequencing, and adaptions in temporary works throughout your project.

Available services for your project

PERI can provide multiple services to assist with your projects.

VARIOKIT VTC Tunnel Carriage

The VTC Tunnel Formwork Carriage is an optimised project solution that accelerates the work process enormously. Depending on the project, it is possible to choose between an entirely manual operation or one completely equipped with hydraulic equipment. With hydraulic equipment for shuttering and striking, the efficiency of the application can be increased. Workloads are minimised for positioning, striking and moving operations.
