ITESSA has renewed and updated the MK2 system technical approval, officially known in Spain as the Documento de Idoneidad Técnica (DIT). The new document, DIT 455R/26, is available to view and download, giving architects, engineers and contractors access to the system’s current technical documentation.

Issued by the Eduardo Torroja Institute for Construction Science (IETcc-CSIC), the document identifies the system and sets out the technical framework for its assessment. Reviewing it is an important step for professionals considering MK2 for a project.

A Technical Reference for Designing with MK2

DIT 455R/26 identifies MK2 as a system of load-bearing reinforced concrete panels with an expanded polystyrene core and names ITESSA as the document holder.

For architects, engineering teams, contractors and developers, this document provides a shared source of technical information. Professionals should consult the complete document and review its scope and conditions when considering how to apply the system.

The DIT should be read alongside each project’s specific requirements. It supports the work of the professionals responsible for design, structural calculations and construction.

What Does This Renewal Mean for Professionals?

The publication of DIT 455R/26 allows project teams to update the documentation they use to assess and specify the MK2 system. We therefore recommend reviewing DIT references in project files and technical libraries wherever MK2 is being considered.

Updating these references helps teams:

• Identify the current version of the document.
• Access technical information directly from the official source.
• Work from the same reference across project disciplines.
• Base technical enquiries on the updated documentation.
