GRP Advantages

Reliable operational service life of over 150 years

Global use and acceptance by major water and sewage authorities all around the world

Fully automated production process, allowing for each pipe to be manufactured with the specific properties required for its application and operation demands

High stiffness classes available (e.g. for areas with weaker soils)

Light weight and convenient length. GRP pipes weigh only ¼ of ductile iron pipes and 1/10 of concrete pipes. This leads to considerable savings through reduced transport, nesting, handling, and installation costs

Corrosion resistance over a wide pH range

No electrolytic corrosion. GRP pipes require no cathodic or other type of protection

Ability to withstand high longitudinal compressive loads (2-3 times higher than concrete) that occur during pipe jackingGRP pipes require no cathodic or other type of protection

Low coefficient of thermal expansion

Excellent hydraulic flow characteristics. Smooth internal pipe surface, resulting in significantly lower friction than with other materials
