Pressure-resistant, hygienic, award-winning: Our SAERTEX-LINER H2O offers optimized characteristics for the trenchless rehabilitation of potable water supply lines using the UV-CIPP process. The UV-cured GFR pipe liner is approved in over 12 countries and won the ISTT Innovation Award in 2019. It is available in two design variants.
- Type S+: low-cost alternative for low operating pressures up to 1 bar Type S+
- XR: suitable for potable water supply lines at pressures up to 33 bar
Innovative and proven technology
To date, the SAERTEX-LINER H2O was used in over 100 projects for 300 UV-CIPP installations and has proven itself worldwide: from Berlin to Valencia, Shanghai to Stockholm, and Moscow to New Jersey.
Advanced hydrailic engiineering
Smooth surfaces coupled with low wall thicknesses maximize flow rate in supply pipes.
The tight-fitting, independent-action pipe liner absorbs inner and outer loads, withstands pressures up to 33 bar, and is a liner certified to Class A (DIN EN ISO 11295) and to Class IV (AWWA M28).
