Quality Assurance
The quality of reinforced concrete parts and structures depends on factors which have to be controlled in the production phase. This is true for parts produced at the building site and for pre-fabricated ones. Imponderabilities lead to fluctuating qualities. This is true for all products. The fluctuations range from acceptable divergences to untolerable serious failures. Hence the quality of products should be checked.

The most decisive criterion for the prove of product quality is the determination of a threshold defining the maximum allowed deviation from a planned product feature. Samples for such thresholds are the minimum concrete coverage of reinforcement bars, the maximum allowed crack width of concrete structures, the minimum thickness of concrete slabs, the maximum percentage of pores which may be resolved with by eye from a certain distance at viewable building surfaces, etc.. After definition of the threshold it must be proved that the existing values fall below of this threshold. Ideally this proof of quality is achieved before further costs arise.

Betontest supports you in your quality assurance process with the application of adapted testing techniques. We also offer consulting services for the invention of reliable procedures defining inspection targets which are adapted to the product quality needs and the achievable targets utilizing state of the art inspection techniques as well. Betontest assists you in the quality control of your products, in the application of product inspection techniques, which may be performed by you or by us and in the preparation of quality documentation. Quality controlled products provide your customers safety and you advantages in a highly competitive market. Show your customers that you have an eye at the critical points to give them the best product.

Concrete Integrity Assessment
In order to assure the quality of highly exploited, extreme tall, pre-fabricated piles the computational engineer requested the application of non-destructive testing to assure the integrity of the used high-strength fibre concrete. The concrete contained plastic and steel fibers as well. In addition the piles contained a huge amount of reinforcement. Hence there was a certain risk for the presence of honey combing and voids. Betontest examined these piles utilizing ultrasound reflection technique and proved the absence of non tolerable voids.
