Manhole/Catch Basin Chimney Type
No over-sizing of structures required for a conventional storm sewer system or storm water retention system
- Factory welding of a custom-made chimney with a smooth or corrugated exterior wall on a main pipe or a manufactured accessory (elbow, tee, etc.).
- The chimney diameter can be equal to or less than that the main pipe, which prevents oversizing it, reduces the amount of work during installation and at the same time, lowering the cost of the whole system.
- Its use eliminates the limit constraint of the angle between connections.
- Much lighter than traditional manhole, it doesn’t require the use of higher capacity lifting equipment, such as a crane, thus making the installation easier and the execution of the work quicker on construction site.
- Manhole/catch basin chimney type with smooth exterior walls eliminates the need for frost-resistant geocomposite.
- As it is made from HDPE, it has excellent resistance to de-icing salts, abrasives, chemicals and vibration.
- Withstands CL-625, H-25 and HS-25 loads.
- Use of adjustable frames and covers available.
