  • The GFRP prepreg is manufactured ready-to-wrap.
  • The fully assembled product facilitates easy handling at the construction site.
  • The GFRP prepreg is highly adaptable to the respective material.
  • Excellent curing speeds.
  • High durability makes it possible to use minimal wall thicknesses.
  • Environmentally friendly processes, as chemical additives are unnecessary.
  • No pipe casing necessary during curing.

Our GFRP laminate consists of an ECR glass fabric. It distinguishes itself by a high corrosion resistance against various chemical and physical influences.

Brandenburger offers two different versions. For the normal application in the earth, a UP resin (unsaturated polyester resin, acc. to DIN 18820 group 3; type 1140), which is temperature resistant up to 50 °C.

The second version is a VE resin (vinyl ester resin, acc. to DIN 18820 group 5; type 1310), which can be used under especially aggressive environmental influences.
