The correct use and application of a multitude of different materials is a determining factor in construction project quality. The quality of construction products is usually deemed self-evident, but you can also demonstrate this through a product certificate. To support the certification process, Kiwa can perform a wide range of tests for you in one of our internationally accredited 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 concrete and plastics, asphalt and metal products.
