Building Materials

Kiwa supports you with all services concerning testing, inspection and certification of concrete according to EN 206 and concrete products. For in-situ concrete, we inspect and certify e.g., according to national standards. Furthermore, we have all the testing facilities for in-situ testing and laboratory testing.

Testing, inspection and certification of floor coverings. Waterproofing membranes including liquid applied waterproofing and kits (for waterproofing against water and/or steam).

The Plastica Seconda Vita (PSV) mark is the first European Environmental Product Certification system for products and materials obtained from the valorisation of plastic waste.

With ReTHiNK you can independently create life cycle assessments and EPDs for your products. A life cycle assessment (LCA) provides information on the environmental impacts (such as global warming potential, eutrophication potential or resource consumption) of your product over its entire life cycle.

The objective of this guideline is to guarantee the drinking water quality by specific relevant additional testing and criteria on the barrier properties of the piping system for an operation period of 50 years in polluted soil.

Effective and long term performance of rubber seals is essential to prevent leakage of pipelines and subsequent spillage of water and high costs for repair and damage. Increasingly, authorities, pipe system suppliers and other parties in the chain of custody are demanding proof of quality of rubber seals.

Safe electrical installations are essential to a property and a major part of any construction project. Kiwa Inspecta helps you to ensure that your property and operation has safer electrical installations and your employees are properly trained to minimize danger.

Do you have questions about the composition or nature of a polymer material, component, a contamination or a chemical attack? Good to know that Kiwa has a large number of laboratories that are well equipped with a broad variety of different chemic...

Independent arbitration for polymers

Plastics are often used out- or indoors exposed to daylight or to daylight behind glass for long periods. The effects of daylight, heat, moisture and other climatic stresses may have influence on the aesthetic and mechanical properties of plastics and for that reason the resistance to these effects is investigated.

Polymers are widely used in construction, building and infrastructure. Construction and utility parts in buildings are often partly or completely polymeric or elastomeric products. This can be as wall panels, roofing materials, piping systems, seals, coatings and a large number of other products.

Reliablity engineering of plastic and rubber products. The realisation of reliable polymer and rubber products starts in the design or engineering stage. There the fundamental choices are made that have a major influence on the functioning of the product in the end.

Within the Kiwa organisation there are a large number of accredited laboratories. This means that the scope of possible tests within the entire Kiwa Group is so wide that is impossible to mention them all here. Although not limited to polymer test...

Wind-uplift test

The quality of aggregates and fillers is defined in the product standards EN 12620 (concrete), EN 13043 (asphalt), EN 13242 (unbound and hydraulically bound building materials) or EN 13383-1 (armour stone) depending on the field of application. Kiwa tests aggregates with several methods.

Kiwa provides FPC/Chimney inspection and certifications. CPR/Chimney Factory Production Controls as per EN 1856-1/-2, EN 13084-7, EN 14989-1/-2 & Certification with Kiwa: Comply with regulations, have a continuously audited & regulated workshop and products.

For construction products for which a harmonized European standard is not available (e.g. due to special features), there is the possibility of applying a voluntary CE. For the voluntary route, the first draft of a European Technical Assessment (ETA) and/or European Assessment Document (EAD) is mandatory.

In Germany, plastic products of all kinds as well as rubber products that come into contact with drinking water must meet the hygienic and toxicological requirements of the guidelines of the Federal Environment Agency test (UBA). This is described in the elastomer guideline as well as in the KTW guideline.

Kiwa supports you in obtaining the necessary certification and carries out the annual inspection of the plant as well as regular audit testing of your products in accordance with the prescribed standards.

When things go wrong, one needs a quick and reliable answer to a series of questions. For this experts are needed who have experience in a broad range of products and applications. Often a certain failure has occurred earlier in a total different application.
