SAERTEX-LINER® H2O
POTABLE WATER APPROVALS WORLDWIDE
Pressure-resistant, hygienic, award-winning: SAERTEX-LINER® H₂O offers superior mechanical characteristics for the trenchless rehabilitation of potable water supply lines using the UV-CIPP process. Our UV-cured GRP pipe liner is approved in over 14 countries and won the ISTT Innovation Award in 2019. It is available in two design options:
- 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

BenEfits
Proven innovative technology
SAERTEX-LINER® H₂O has been used on 300 UV-CIPP installations on over 100 projects to date and has proven itself worldwide – from Berlin to Valencia, Shanghai to Stockholm, and Moscow to New Jersey.
Advanced hydraulic engineering
Smooth surfaces coupled with low wall thicknesses maximize flow rate in supply pipes.
Fully structural
The tight-fitting, independent pipe liner absorbs inner and outer loads and withstands pressures up to 33 bar. It is also certified to Class A (DIN EN ISO 11295) and to Class IV (AWWA M28).
With support services
Our wide range of services, including ongoing support from our product experts and engineers, helps ensure the smooth progress of your construction project from the conception phase through to its successful completion.
