A large variety of chamber bases are available pre-fabricated with a large range of options for inlets and outlets in a variety of diameters.

These bases can be good option when time is limited as no fabrication lead time is required. Some also come with pre-fabricated risers built in to the unit, further saving time and reducing costs.

These chambers, like Rotoniv chambers can be adapted directly to twin wall pipe using the same method of welding a coupler of suitable size directly to the chamber base, useful for deep chambers where a large number of risers would be required. In some situations, such as when using a UG616 pipe, can also be directly welded to the chamber base.

Available in a variety of diameters with multiple inlet and outlet options.
