With the new MultiFlex 1D and 3D liners, Trelleborg Seals & Profiles is launching an innovative development of a proven product that focuses specifically on the challenges of modern house connection renovations. The liners combine maximum flexibility with robust material quality and enable efficient, trenchless renovation even under demanding conditions.
The MultiFlex 1D Liner is ideal for nominal diameters from DN 30 to DN 200 and impresses with its final wall thickness of ≥ 3.0 mm. It can handle multiple bends up to 90° and is temperature resistant up to 100 °C when used with a calibration hose.

The high-quality polyurethane coating ensures reliable installation thanks to its flexibility and resilience.

The 3D version of the liner goes one step further. It adapts to bends and to dimensional changes – ideal for complex pipe networks. In addition, the MultiFlex 3D liner offers a number of additional advantages:

Production without transverse seams up to 90 m in length: No transverse seams mean fewer weak points and greater structural integrity
Final wall thickness ≥ 3.00 mm: Benefit from additional stability and durability, ideal for applications under high pressure and stress conditions
Curing without calibration hose up to 80 °C: Saves time and effort during installation by curing the liner at higher temperatures
Optimal impregnability: Ensure even and complete saturation of the liner for optimum adhesion and strength
Higher burst pressure resistance: Greater safety and load-bearing capacity in critical applications
Easier expansion: Facilitates installation, especially in tight or hard-to-reach areas

Matthias Peppel, Product Manager for Consumables at Trelleborg, explains: “With the MultiFlex 3D Liner, we offer our customers a solution that not only impresses from a technical standpoint, but also significantly simplifies processing on the construction site. The combination of flexibility, temperature resistance and ease of handling makes it a true all-rounder.”

Both liners are compatible with various curing processes – from ambient temperature to hot water and steam to light curing – and can be processed with resin systems such as Trelleborg HC120+ or RayCure UA.

Approved quality – with certainty

The MultiFlex Liner in combination with the HC120+ epoxy resin has been approved by the German Institute for Building Technology (DIBt). The approval number Z-42.3-468 confirms the high quality and safety of the system for use in trenchless pipe rehabilitation. The liner thus meets all requirements for a permanently reliable and standard-compliant rehabilitation solution – even in public areas.
