Together, let’s build a future where manhole covers aren’t just seen but truly appreciated for the vital role they play in our urban ecosystem.

Excavation and Subgrade Preparation

These types of manholes are about two to three feet or 75-90 centimeters of shallow depth. They are normally placed at the starting of a sewer or drainage water conduit passage and in the areas that are not subjected to heavy traffic. These types are suitable for maintenance work and are also known as inspection chambers with a light lid as a cover at its end.
