How does water temperature and ambient climate affect the durability of Plastic Manholes?

Plastic Manholes are resistant to a wide range of temperatures from -20°C to 45°C. No water is absorbed which can freeze in
winter destroying the structure. It is well known that water freezing between concrete elements can destroy them, whereas plastic parts are not affected by the same conditions,

Details:

  • No water is absorbed which can freeze in winter destroying the structure. 
  • It is well known that water freezing between concrete elements can destroy them; where as plastic parts are not affected under the same conditions. 
  •  Regarding installation in asphalt, the manhole cone and riser should not be in direct contact with the asphalt (use of a concrete support plate is advised).
