Building materials

The correct use and application of a multitude of different materials is a determining factor in construction project quality. The quality of most of the construction products has to be proven by a certificate according to international or national standards. To support the certification process, Kiwa can perform a wide range of tests for you in one of our (internationally accredited) state-of-the-art laboratories.

Additionally, the correct fitting, assembly and use of construction materials are decisive in achieving the required level of building quality, for which a process certificate offers quality assurance. Kiwa has extensive expertise in the area of independently monitoring the quality and use of building materials such as timber, concrete, steel, roofing and ceramic products.

We take sustainability into account as well and help you to demonstrate that your products are produced in a sustainable friendly way.
