Waterproofing products and kits are used for preventing water from penetrating the building structures for instance in wet rooms. We offer testing services for product development, product approval, and factory production control. The test results can be used for VTT Certificate or for CE-marking of the products and systems through ETA-procedure (ETAG-022 Watertight Covering Kits for Wet Room floors and or walls).
VTT Expert Services Oy determines by testing the properties of all liquid based water barriers, sheets, and mats including their respective accessory products. Most of the testing methods of VTT Expert Services Ltd are accredited by national accreditation services (FINAS T001). Additionally, VTT Expert Services Ltd is a notified body for a number of product standards.
We are happy to serve you in all your needs concerning testing, CE-marking, product approvals and factory quality control of water barrier products and kits.
The testing methods
We comply with the requirements of product and testing standards but when needed and possible we can also adapt the testing programs to your needs such as for product development purposes.
