Concrete sewage manholes are frequently replaced with sewage manholes made of polyester fibreglass reinforced resin, which are applied in all sewage systems.
Advantages of polyester manholes:
✔ Lesser manhole weight,
✔ Completely waterproof and non-porous,
✔ Extreme smoothness of the manhole walls,
✔ The ease of pipe connecting and assembly means lesser time of manholes installation,
