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.

Supporting structures cost-effectively erected with system – with materials and expertise from a single source
With PERI SCS, the loads from the fresh concrete pressure are transferred without formwork ties through the brackets into the climbing anchors of the previous concreting section.
PERI UP Flex Modular Working Scaffold: Extremely flexible work scaffold for a wide range of applications.
Shoring system for very large loads in bridge constructions as well as for special applications in industrial construction
The 7 km long west section of the Thames Tideway Tunnel from Acton Storm Tanks site in West London towards Carnwath Road Riverside in South West London was supported by KERN Tunneltechnik.
KERN Tunneltechnik has engineered and supplied the automated tunnel formwork system with live data analysis and PLC control units, comprising of 6 hydrostatic shutters, to support these works. The fullround formworks with a diameter of 6.5 m have been moved and set by 2 multifunction gantries. The system has been completely pre-assembled and tested at KTS.
