Our calibration tube features several tube types and consistent high quality


Our Calibration tube can be used multiple times and are especially suitable for “open-end” inversion work.

  • Calibration tubes, partly extra reinforced

  • Sizes: 2 in. to 24 in.

  • Base weight: approx. 375 to 640 g/m²

  • Temperature resistance: partly up to + 176 °F

Our Liner is based on polyester needle felt which ensures consistently high quality.


Depending on the liner/resin combination used, the following properties can be realized:

  • Bendable to 87° with a virtually wrinkle-free result.

  • Extreme radial expandability, a reduction in nominal diameter or 1-2 dimensional jumps are possible.

  • Available in various wall thicknesses.

  • E-modulus up to 3,200 N/mm².

  • Partly high temperature resistance, depending on type also ideally suited for steam curing.

  • Double and partly also triple stitched seam.

  • Seam sewn, therefore easy and even soaking.

  • Inexpensive and therefore economical to use.

  • Highly resistant to chemicals.

Our Resins, the outstanding impregnation behavior and the excellent bonding with the old pipe distinguish these elastified silicate resins in addition to their excellent resistance to various media after curing. Specially developed formulations prevent foaming when exposed to moisture and water.


The different product variants enable a high degree of versatility and variability in terms of processing and curing times:

  • Impregnates glass fiber mats or polyester fleece well.

  • Adheres even to damp surfaces

  • Does not foam, not even if water is infiltrated

  • Cures well in thin layers

  • The formwork can be easily removed

  • Excellent physical-chemical properties

  • Is also resistant against aggressive water, acids and alkalis and does not saponify.

Our glass fiber mats, the corrosion-resistant bi-directional glass fiber complex (ECR glass fabric) for partial repair work using short liners


  • Available in various base weights  and roll widths

  • Ideally suited for a variety of applications and pipe dimensions.

Our T-Wrap, ideal for household connections of all kinds.


T-WRAP, a special cap made of glass/felt material, also equipped with a 45 cm long shaft, featuring the special effect that the cap rim is not round but rectangular and large enough that it sticks to the upper semicircle of the pipe, thus additionally stabilizing this area of up to 180°.
