New test certificates for Potable Water Applications

For the highest quality standards for potable water applications the test certificates for Zemdrain® CPF liner are available for the DVGW requirements (W 270 and W 347). Now new and additional - with extended duration in formwork status!

The requirements of the DVGW (German standardization body for the gas and water industry) regarding the suitability of the "Zemdrain® Classic TW" formwork liner for drinking water have been confirmed by the Institute of Hygiene.

Additional drinking water tests with extended duration in formwork status

In the existing test certificates, forms were removed from concrete test specimens after a short time. In order to demonstrate the added value and effectiveness of Zemdrain® Classic to our customers, even under extreme conditions, MAX FRANK decided to carry out these spectacular tests. Our aim was to leave Zemdrain® Classic TW on the concrete test specimens for "as long as possible and technically feasible".  

The results of the additional drinking water tests "with extended duration in formwork status on" were convincing: there was no fibre adhesion to the concrete and therefore a very good concrete surface quality. The tests were confirmed by the renowned Institute of Hygiene.
