Our Polyethylene Inspection Chamber (alternatively called manhole, utility hole, cable chamber, maintenance hole, access chamber, sewer hole or confined space) is the top opening to an underground utility vault used to house an access point for making connections, inspection, valve adjustmnets or performing maintenance on underground and buried public utility and other services including sewers, telephone, electricity, storm drains and other services. Our polyethylene manhole will also contribute to the protection of the environment and your absorption pit.


Manholes are required in domestic, commercial and municipal sewerage networks. Some of their benefits are listed below:

- Easy storage on site
  Due to the light weight of the polyethylene manhole/inspection chamber, storage on site is extremely easy by stacking them up vertically, hence saving space.

- Extremely fast installation
  The significant lower weight of the polyethylene manhole/inspection chamber compared to concrete ones enables easy installation.

- No space constraint issue
  Polyethylene manhole/inspection chamber can be easily lifted by hand, hence has excellent workability at space constraint issue.

- Environmentally friendly
  Our manhole/inspection chambers are made up of polyethylene.

- Lower maintenance cost
  Once installed, polyethylene manhole/inspection chamber do not require maintenance for a very long time; this is due to the extremely smooth internal surface which ensures self-cleaning effect.

- High chemical resistance and corrosion resistance
  The polyethylene manhole/inspection chamber has exceptional long lifespan due to excellent chemical and abrasion resistance of the material.
