2 Glass liners pros and cons Length (km) Relining market trends: Installed liners in Germany Glassliners Feltliners Source: 40 Jahre praktische Erfahrung mit dem Schlauchlining Prof. Dr. Ing. V. Wagner - April 5, Bonn German relining market showing steady growth Glass liners have increased share above 50% Other markets to follow PROS Superior mechanical proper>es short and long term High s'ffness (E- modulus) Low reduc'on factor (10000 hrs tes'ng) Thin wall construc>ons minimal diameter reduc>on Excellent corrosion resistance Advantex ECR Good fit to the old pipe High stretchability of the liner Low shrinkage (high glass content) Fast installa>on High cure speed Extra beneficial for limited length Endless pot life (in the dark) Leak >ght Low environmental impact styrene 'ght foils (inside and outside) low energy consump'on for curing rela'vely light equipment CONS Maximum wall thickness limited to about 12 mm Risk for under cure at backside of thick wall laminates Reduced pot life in case of thick wall curing with support of peroxides Difficult temperature control in case of thick wall curing with support of peroxides. 2

3 CIPP glass liners produc'on technologies Folding Winding Liner build- up Mul'ple layers of woven roving mat complexes Possible use of surface veil Stretching by layers sliding Liner build- up Mul'ple layers of mat complex or mat combined with LOC (long oriented chop) Possible use of surface veil Stretching provided by fabric 3

4 CIPP glass liners - Construc'on Fiber orienta>on Longitudinal direc'on to handle pull in forces Hoop direc'on suppor'ng ring s'ffness Long oriented chop Excellent orienta'on in hoop direc'on Superior mechanical proper'es Easy to stretch to ensure close fit to host pipe Advantex ECR Superior corrosion resistance over E- glass Reduced risk for failures & longer life 'mes Boron free offering environmental benefits 4

5 Ultrapipe F - new fabric design for folding Ultrapipe F Unique fabric construc'on providing stretch ability Even in folding (overlaps), main part of the expansion is provided by fabric stretching Easier/smoother liner set- up Reduced risk for uncontrollable liner stretch at overlaps 5
