Manholes
When constructing sewer systems, reliable and durable access for inspection and maintenance is essential. HDPE and MDPE inspection chambers provide an efficient solution for road construction as well as industrial and residential applications. These inspection chambers are manufactured from 100% polyethylene and combine high mechanical strength with excellent watertightness.
Thanks to their lightweight and modular design, you can install these chambers quickly and without a heavy foundation. The prefabricated structure and integrated seals ensure a leak-proof connection without the need for additional mortar or adjustment work. Furthermore, the chambers are BENOR-certified and compatible with various piping systems such as PVC, HDPE, and PP.

Benefits of control rooms in PE
Resolution quality
- Because they are made in one piece, the surface of the various channels of the PE inspection chambers is exceptionally smooth (drain very quickly, little or no deposits).
- For some inspection chambers, particularly those made of concrete, the inlets and outlets must be adapted to the connection pipes. This is not the case for PE inspection chambers, as the seal is already integrated here. There is therefore no risk of clogging and the seal is guaranteed.
- No adjustment work needed.
- no mortar residue when securing the pipes.
- no canal to be inserted in the bottom of the room.
Sustainability
- Collinet's PE inspection chambers are designed to last a long time.
- In practice, they are virtually indestructible.
- The EN 14830 standard supports this claim by measuring the deformation of the monitoring chambers over a 50-year period.
Weight
- light, easy to handle and easy to install;
- no construction equipment needed;
- exceptional time savings.
Corrosion-resistant
PE is perfectly suited for its intended use. The material is exceptionally resistant to dirty water and retains its smooth appearance. Polyethylene is not affected by the passage of time.
Flexible
They are supplied either pre-welded (making them easy to install) or as separate components. In both cases, the control rooms are highly modular and incredibly versatile.
Waterproof
One of the major advantages of the monitoring chambers in PE (tested at 0.5 bar).
FAQ
1. When do you choose an HDPE inspection chamber instead of concrete?
When speed of installation, watertightness, and corrosion resistance are important. HDPE manholes are lighter, easier to install, and more resistant to chemical influences than concrete.
2. Which standards apply to HDPE inspection chambers?
These manholes generally comply with NBN EN 13598 and feature BENOR certification, which guarantees quality and compliance in drainage systems.
3. How is the watertightness of an inspection chamber guaranteed?
Due to the seamless construction and integrated seals in the connections. As a result, no additional sealing is required on-site and leakage is prevented.
4. What role does the inner wall play in the operation of the well?
A smooth inner wall ensures optimal flow and limits deposits, which reduces the need for maintenance.
5. Are HDPE inspection chambers suitable for industrial applications?
Yes, thanks to their high chemical resistance and robust construction, they are suitable for wastewater, process water, and aggressive environments.
