    • Serge Ferrari Composite Membrane:
    Précontraint 1202 S2

  • Serge Ferrari Précontraint 1202 S2 composite membrane is impervious, corrosion-proof, aesthetic and durable….. unequalled characteristics that enable it to contain efficiently olfactory, gaseous and noise emissions from the Saudrune SIVOM composting facility, whose overall design is based on HEQ construction principles (recyclable materials, energy savings, etc.).

    Since 2006, the site accommodates a keynote installation that facilitates the environmentally sustainable conversion process and improves its reliability. The composting unit processes sludge from the local sewage treatment facility. After incorporation with green waste, this sludge is treated and then converted into a natural fertilizer with a high agronomic potential.

    Innovative architecture

    The plant’s metal-textile structure represents a break-through in France. It is in fact reversed: the galvanised steel tubular part is externally located to prevent risks of corrosion associated with internal gas emissions.
    The ovoid steel structure weighs 33 tonnes, while the 2,000 m² of Serge Ferrari composite membrane weigh only 3 tonnes (180 HF welded pannels, 3 km of welds). This composite structure can resist 160 km/h winds!
    TextiDome, an exclusive Prat SA design, has already been used on a number of sites worldwide.

    Environmental impact reductions

    The Précontraint 1202 S2 membrane forms an impenetrable wall, which ensures containment of noise, odours and gases. Yet, imperviousness is not synonymous with opaqueness and the Serge Ferrari Précontraint 1202 S2 material is effectively outstanding due to its translucence, which ensures the ideal light contribution for reconciling energy savings and working comfort.
    Moreover, emanation curtailment contributes to reducing environmental pollution, conserving non-renewable natural resources (water, air, etc.) and creating new resources (compost for enriching the soil in fields and green spaces).
    Environmental impacts are thereby better controlled and, all the more so, since at the end of its life, the Précontraint 1202 S2 membrane can be completely integrated into Serge Ferrari’s  operational recycling chain Texyloop, which also registers in this virtuous loop.

    Précontraint 1202 S2: unique performance characteristics

    > A composite membrane:
    • 100% waterproof and 100% corrosion-proof
    • Durable: outstanding structural strength and aesthetic quality
    • Translucent
    • 100% recyclable through Texyloop

    Manufacturing expertise

    The exclusive advantages of Précontraint technology

    • precontrain_620x320


    • a woven base cloth of high tenacity polyester threads,
    • a coating with the membrane under constant tension in both the warp and weft directions throughout the entire manufacturing process
    • a high performance polymer surface layer with a constant and greater thickness over the top of the yarns,
    • a dirt-resistance surface treatment.
    • un traitement de surface anti-salissure

    Controlled dimensional stability
    Précontraint Serge Ferrari technology guarantees the material’s exceptional dimensional stability, which is almost identical in warp and weft directions. Deformation resistance in the weft direction exceeds that of conventional coated fabrics. This exclusive advantage is very important during textile tensioning.


    Précontraint Serge Ferrari composite materials offer high resistance to stretching due to their very low absorbency.

    In addition, due to the dual advantage exceptional stability and straight threads, Précontraint Serge Ferrari composite materials stretch three times less with the weft than conventional coated fabrics.


    Longation in the weft direction under a 200 daN/m load over a period of 100 hours.
    Then residual elongation without load.

    Totally controlled uniformity
    The bi-axial tension central to Précontraint Serge Ferrari technology ensures rigorous control of weft threads and absolute running thread compliance throughout all production batches.


    Précontraint Serge Ferrari® membranes ensure total compliance along the thread, (identical throughout all production batches).

    The weft threads of conventional coated fabrics deform significantly and variably depending on the production batches.




    Enhanced durability
    Material lightness during handling is an important criteria in facilitating making up and installation. Précontraint Serge Ferrari technology ensures this lightness, whilst guaranteeing a thicker coating layer at the top of the yarns. The polyester base cloth is therefore better protected against climatic conditions.




    Thicker coating on the thread crests ensures that the physical properties of Précontraint Serge Ferrari membranes are preserved over time – a key factor in the durability of your projects.
