FAQ
Practical
The costs depend on the scale and nature of your project, for example: the number of structural components to be examined, the type of laboratory analyses or the scope of a certification process. Contact us for a quote, tailored to your specific situation.
The turnaround time varies depending on the process. A simple inspection or field measurement can be completed within a few days to weeks, whilst a comprehensive damage assessment or certification process, including laboratory analyses and audits, can take several weeks to months. We will provide you with a realistic timeline in advance.
Damage, inspection and condition
In the event of cracking or damage, we first assess the technical condition of your structure to identify the problem and required repairs.
We investigate the nature, cause and extent of the damage and identify risks to safety and durability. We use field measurements and laboratory testing, including analyses of concrete strength, de-icing salt penetration, carbonation, reinforcement corrosion, chloride profiles and degradation of surface finishes. Based on our findings, you will receive evidence-based advice that will enable you to draw up repair plans, ensure safety and extend the service life of your structure.
A condition assessment identifies risks of future problems before any visible damage is present, whilst a damage investigation examines the cause and extent of damage that has already been identified.
In a condition assessment, we primarily use non-destructive testing methods, supplemented where necessary by samples and laboratory analysis. This supports a preventive maintenance approach and is also useful when repurposing existing structures, particularly where little data is available, or for quality control of new builds. We initiate damage investigation following signs, such as cracks or corroded reinforcement, and focus on the exact nature, cause and extent of the problem.
Sustainability and certification
You demonstrate recycled content by having it certified by us in accordance with ISO 14021.
The process involves several steps: you collect evidence from your suppliers regarding the use of recycled raw materials, draw up an interpretation document in which you justify why certain raw materials are classified as recycled, and calculate the quantity of recycled material in your product.
We then assess the evidence provided by your suppliers, review your interpretation document and verify your calculation. We then carry out an audit at your production site, during which we examine the entire production process, including the procurement of raw materials and quality control.
Yes, we can assist in several ways with a life cycle assessment (LCA).
We advise you on how to gain insight into and improve the environmental impact of your services, and can carry out the full LCA for you, including the correct inclusion of environmental profiles in the National Environmental Database (NMD) or your preferred EPD platform. In addition, we develop calculation tools that enable you, as a manufacturer, to calculate the environmental data for your product yourself. This is also useful for assessing the impact of improvement measures yourself.
If you manufacture or reuse building materials within the circular economy, testing for substances of very high concern is often necessary to comply with legislation and regulations.
We identify which SVHCs are relevant to your raw materials or waste streams and support you in classifying and reporting them correctly, so that you can produce safely and in a circular manner without unnecessary risks.
About us
INTRON, opgericht in de jaren ’70, werd in 2010 onderdeel van SGS. Sindsdien zijn de tests op beton en bouwmaterialen voortgezet, versterkt door onze lokale expertise en ons wereldwijde netwerk.
