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, 
   ✔  	Low maintenance costs,
   ✔  	Low transportation costs,
   ✔  	Extremely efficient sealing of the manhole pipe, 
   ✔  	They possess a sufficient deflection and axial hardness, so that certain sliding of the  
   ✔  	Manhole quality ensured for all kinds of application.
Manholes are made as standard, tangential, and as defined in the client’s request. 
 
Polyester sewer manholes are a quality, practical, and functional solution for wastewater drainage (whether faeces, industrial or surface wastewater), profitable in the long terms.
