Paragon Underground Drainage Chamber Base

An inspection chamber base forms the bottom section of a below ground access chamber, positioned where branch drains meet a main run or where the drain changes direction. Pipework connects into the sockets around the base. Inside, a formed channel carries flow from the main inlet across to the outlet, with the side inlets entering alongside it. Once built up to ground level, the chamber allows the drain to be inspected, rodded and surveyed by camera without excavation.

Each base is the starting point of a modular chamber. Risers stack on top to bring the chamber up to the required height; the chamber is then finished at the surface with a matching 320mm or 460mm cover and frame.

• Modular chamber system: Forms the base of a chamber that is built up with risers and finished with a cover and frame.
• Formed flow channel: The internal channel carries flow through the chamber from inlet to outlet.
• Multiple connections: Four or six sockets allow several branch drains to join the main run at one access point.
• Choice of configurations: 320mm and 460mm bases, with all-110mm connections or a 160mm and 110mm combination.
• Access without excavation: Provides a point for inspection, rodding and camera surveys at ground level.
• Made in Great Britain: Manufactured in Great Britain by Polypipe, and finished in black.
