Durability assessment

As reinforced concrete structures generally have a service life of at least 50 years, durability is one of the most important requirements for concrete construction work. The range of services we offer in the field of durability assessment ensures methodically based, reliable checking and optimisation of the resistance of concretes to a variety of environmental impacts.

Structure management

The durability of reinforced concrete structures can be impaired by environmental influences. We provide support for the diagnosis of existing structures, the assessment of inspection results and possible repair planning.

Approval inspections and accompaniment of approval procedures

Our approval inspections and accompaniment of approval procedures help you to verify the basis for CE marking (European Technical Assessment, ETA) and the suitability of construction products for specific areas of application (national approvals for concretes, concrete constituents and cements, for example). The range of services we offer encompasses all stages of the approval procedure, from preliminary trials right through to expert reports.

Life cycle assessment and sustainability assessment

Certification systems such as DGNB, LEED or BREEAM are increasingly being used to assess the sustainability of new buildings. The sustainability concept commonly employed is based on a three-pillar model, made up of economy, ecology and social aspects. Life cycle assessment of building materials provides important input data for such sustainability assessments. We develop life cycle assessments for cement and cement-bound building materials as a basis for environmental product declarations (EPD).

Customer-specific services

Our customer-specific services help to optimise your products and open up new areas of application. Our experienced specialists can offer their support if there is a need for your products to satisfy extended verification of suitability or meet special requirements. On the basis of the latest scientific and technical state of the art we will assist you with the planning of development steps and the optimisation of properties and verify the suitability of your construction products (e.g. cements or concretes) for specific areas of application. We will additionally support you throughout the course of the necessary approval procedures and issue product certificates.
