SAERTEX-LINER® H2O

SAERTEX-LINER® H2O

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 12 countries and won the ISTT Innovation Award in 2019. It is available in two design options:

  • Type S+: a cost-effective alternative for low operating pressures up to 1 bar
  • Type S+ XR: suitable for potable water supply lines at pressures up to 33 bar

PROVEN INNOVATIVE TECHNOLOGY ON OVER 300 INSTALLATIONS

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 thickness 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).

CUSTOMIZED SOLUTIONS 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.
