Glass-Fiber Reinforced Polymer (GFRP) Passive Anchor Solution for Slope
Stabilization & GFRP Rebar Used in Marine Works

by Pierre Hofmann – Dextra Group


29 February 2024


10:30 am



Glass fibre reinforced polymer (GFRP) has been used in many applications in engineering and civil engineering. These materials were first developed and used in the 1930s in the USA in boats and in aeronautical fields. Glass fibre reinforced polymer (GFRP) bars have high strengths, are light in weight, flexible and can be produced more cheaply than carbon fibre. They are also more durable than steel, as they do not corrode. FRP has been used in mining and tunnelling for decades and more recently used for slope stabilization and concrete reinforcement, due to the durability concerns associated with conventional steel reinforcement.

In this seminar, we will discuss the characteristics of GFRP soil-nails and rebar for permanent usage, the advantages & disadvantages compared to conventional techniques and the applications supplied by Dextra on existing projects.

About the Speaker:

Pierre graduated with a Master of Engineering from “Ecole Centrale de Lille” and a Master of Science in Project Management from “SKEMA Lille”. He joined Dextra in 2007 to develop ‘Fiber Reinforced Polymers’ (FRP) soft-eye technology used in metro systems. He led the development of FRP anchors used first on Doha metro (Qatar) and then internationally. Lately, he has been promoting FRP as a permanent reinforcement and a substitution to steel, which was adopted in 2018 on the world largest underground oil-storage cavern. After 15 years at Dextra, Pierre is General Manager - Geotechnical Product-Line
