Flexible liner for bend-heavy networks
The all-rounder liner for bend-heavy rehabilitation networks.
HELIXLINER FLEX is engineered to remove the old trade-off between handling flexibility and structural confidence. It gives crews predictable behavior from wet-out to cure, even in tight geometries.
Perfect For
Complex municipal and commercial networks with dense bends
Bend Navigation
True 90° navigation with controlled expansion and no wrinkling
Wet-Out
3D knit profile supports fast, even impregnation across runs
Installation
Inversion with Sewerbot drum or Sluice Adapter preferred; pull-in-place optional
Overview
HELIXLINER FLEX delivers stable handling in dense branch networks, maintains controlled expansion in tight turns, and keeps curing performance consistent across field conditions.
Key Benefits
Applications
Navigate tight geometry and branch-rich lines while preserving cured-wall integrity and crew control.
Maintain repeatable handling in mixed-access installations where job tempo and predictable setup matter.
Scale structured rehab workflows with a liner designed for repeatability, QA confidence, and throughput.
Workflow
The liner is tuned for consistency at every phase, helping teams keep planning tight and outcomes repeatable across mixed network conditions.
Step 01
Wet-Out
Fast, consistent impregnation enabled by the 3D knit profile.
Step 02
Inversion
Controlled insertion through heavy bends with reduced deformation risk.
Step 03
Cure
Compatible with ambient, hot-water, steam, and UV/LED methods.
Step 04
QA Ready
Predictable outcomes and cleaner verification across projects.
Technical Specifications
HELIXLINER FLEX is tuned for mixed-field operations where handling confidence and process repeatability are priority metrics.
Important product note
Product information on this page is provided for general informational purposes only. Performance depends on application, site, operating conditions, and compatibility with the rest of the system. If a Polinvent product is used together with third-party equipment, liners, resins, curing units, or other components, that combination requires written Polinvent approval. Otherwise, the customer must verify suitability and bears the integration and project-performance risk. Review the applicable SDS, TDS, and product manual where relevant. Binding specifications arise only from the Confirmed Order and the written technical documentation supplied by Polinvent.
