One Million Kilograms of CO2 Saved Using SAERTEX-LINER UPgreen
Read moreIn order to make trenchless pipeline rehabilitation more sustainable, SAERTEX multiCom introduced the SAERTEX-LINER UPgreen at the end of 2020. The company has since used this key innovation in the sustainable production of GRP liners as standard for all SAERTEX-LINERS in the product range with UP resins. To date, the new technology has enabled savings of one million kilograms of CO2.

Pipe Liners: Combined Wall Thickness and Unrealistic Moduli of Elasticity Adieu
Read moreThe so-called resin-rich layers of pipe liners have been subjected to very specific treatment on the German market since the introduction of DIN EN ISO 11296-4 in 2011. The scope for interpretation resulted in a competition developing to achieve the highest modulus of elasticity, which then became synonymous with high quality. However, the resulting characteristic values are dubious in terms of their technical basis. This practice continues to be upheld, although the update to the product standard has now rendered the basis unfounded. The introduction of the AoC document for pipe liners is another reason to deviate from the unique German path.

Wall Thicknesses for Cured-in-Place Pipe Liners
Read moreThe new version of the international product standard for cured-in-place pipe lining, ISO 11296-4, introduced a number of changes in 2018. New terms such as ‘design wall thickness’ and ‘composite’ necessitate greater adjustments for the industry than might initially be apparent. What will planners, manufacturers, testing institutes and construction companies need to consider in future? The following presents a technical article on how theory can be translated into practice, thereby ensuring greater transparency.

CIPP: Annular space and structural integrity
Read moreThe regular existence of excessively large annular spaces between the CIPP and the existing pipeline after installation has been recently the subject of controversial discussions among experts. The various reasons for the annular space as well as the effects on structural integrity are discussed.In the following technical report by Dr.-Ing. Ricky Selle a systematic approach to the topic is made. The possible reasons for the formation of annular spaces are pointed out and classified in terms of their potential. On this basis, the effects on structural integrity of the liners can be quantified.

Styrene-free SAERTEX-LINER ENVIRONMENT now with DIBt approval
Read moreThe styrene-free SAERTEX-LINER ENVIRONMENT was the first GRP liner with styrene-free VE resin on the market to be approved by DIBt. This improves the range of products offered by SAERTEX multiCom for the trenchless rehabilitation of wastewater pipes, especially for applications where it is important to avoid the typical odor of styrene.
