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) 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, glass, roofing, cladding, insulation, plastics, asphalt and ceramic products. We are also a designated Notified Body for a large number of construction products and we can assist you in correctly interpreting the increasingly complex local and European construction regulations (including, for example, CE marking).
