Naue knows both sides. As manufacturer of both Carbofol® geomembranes and Bentofix® geosynthetic clay liners, we provide impartial technical advice across our product portfolio. Where a geomembrane is the right solution, we will specify one. But where your project cannot afford delay and a GCL is technically appropriate, Bentofix® X may be the faster answer.

Market Conditions and Material Costs Are Putting Projects Under Pressure

Rising raw material prices and constrained supply chains are affecting the entire geosynthetic lining market. Not every project can wait for conditions to ease.

Rising Geomembrane Costs Are Hitting Project Budgets

Raw material and energy prices have significantly increased geomembrane manufacturing costs. The result: budget pressure before a single metre of liner reaches site.

Lead Times Remain Extended

Weeks of waiting mean open excavations, idle trades and plant, ongoing preliminary costs — all against a programme that cannot slip.

Contractual Deadlines Cannot Slip

Planning conditions, downstream works packages, sectional completions — the programme stands. Regardless of what the materials market is doing.

Bentofix® X: When Speed and Availability Matter

Bentofix® X is a coated geosynthetic clay liner (GCL) with a sodium bentonite core. It is not a universal substitute for geomembranes — but where a mineral-based lining solution is technically appropriate, it offers decisive advantages in the current market climate:

Describe your project briefly.

Naue engineers will assess within two working days whether Bentofix® X is the right specification — and on what terms.

  • Available from stock: No extended wait — installation begins when your programme demands it.

  • No hot-wedge welding: No certified welding contractor required — less weather dependency, faster programme progress.
  • Self-sealing: Minor punctures are sealed autonomously — no remedial works required.

  • Cost-predictable: Stable manufacturing costs compared to the volatility of geomembrane pricing.

  • Proven: Thousands of installations worldwide — mineral lining technology with an extensive track record.

Not Every Application Is the Same — Which Is Why We Assess Project by Project

Whether Bentofix® X is the appropriate lining solution for your project depends on the technical, civil engineering, and application-specific requirements. That is precisely why Naue focuses not on blanket product claims, but on a robust recommendation tailored to your specific situation.

Which Solution Is Right for Your Project?

Whether Bentofix® X or Carbofol® — we advise you honestly and on a project-specific basis. You will receive an initial technical assessment within 2 working days.

  • Independent assessment by Naue engineers

  • Project-specific suitability review

  • Immediate confirmation of availability and lead times

  • An honest recommendation — even where a geomembrane remains the better choice
