The light curing AlphalinerUP CIPP liner enables particularly time-efficient trenchless rehabilitation processes of up to 300m per day. Especially for inner-city projects, this helps to minimise the impact on residents and road traffic. The service life of a rehabilitated sewer section is 50 years or more.


AlphalinerUP is a latest generation CIPP liner designed specifically for rehabilitating communal waste water sewers.

  • Excellent chemical resistance to communal waste water
  • High mechanical characteristics for long-lasting resilience
  • Unique wearing course on the inner liner surface
  • Optimum solution for circular, ovoid, square, or custom cross-sections



We use a highly resistant polyester resin (UP; classified as per DIN EN 13121 into group 4; DIN 16946-2 type 1140; DIN 18820 group 3) as well as corrosion-resistant ECR glass fibres.

On their inner liner surface, Alphaliners have a special wearing course in compliance with DWA-A 143-3 and DIN EN ISO 11296-4. This wearing course is achieved by a vylene-bonded high-grade resin layer of at least 0.5mm thickness (DIBt approval at least 0.4mm), resp. 0,3 mm (Alphaliner500G). Currently, Alphaliners are the only hose liners in the world offering a defined wearing course thickness.

The AlphalinerUP models exhibit excellent mechanical characteristics and are graded as per DWA-M 144-3 into groups 13 and 20. This qualifies them to withstand the highest structural stress loads at a comparatively small wall thickness.

We offer you the following models:

  • Alphaliner500G-UP
  • Alphaliner1800H-UP

Optionally, we offer these Alphaliners with integrated slide protection and/or pre-liner.
