- For years precast concrete manholes have been the default choice in sanitary and storm water applications.
- Over the years, though, GRP(FRP) Manholes have begun to displace concrete manholes for a number of reasons.
- Advantage of GRP manholes are:
-
- Light weight (1/10th the weight of concrete)
- Quick and easy installation, short construction time
- Complete corrosion resistance inside and outside
- Good hydraulic properties
- Connections to other materials possible
- Delivery as complete components, reduction of construction site risks, factory quality
- Pump shafts, well chambers, sewer overflows, etc. available
- Applications
- Sewage System
- Storm Water System
- Sewage Pump Station
