Continuous height adjustment

Manholes can be equipped with a height adjustment kit, offering the following advantages:

  1. Optimal fit of the upper edge of the manhole level to the surface of the ground
  2. Continuous height and angle adjustment between the head frame and steel frame
  3. All four sides can be levelled separately
  4. Height can be adjusted by up to 50 mm


 

After the manhole has been installed in the foundation pit and the backfill has been compressed to the upper edge of the head frame, the steel frame is then levelled.
