Rain gutter

Centralise and control your networks with our high-strength rainwater inspection chambers!

The rainwater inspection chamber (or connection box) is the essential access point for smart management of your rainwater. Placed at the foot of downpipes or at drain junctions, it lets you collect, redirect and above all inspect your underground network. At Jardiboutique, we have selected sturdy PVC or polypropylene chambers, designed to withstand the weight of the soil and foot traffic. They are essential to stop your rainwater network clogging up and to make access easier whenever clearing or maintenance is needed.

Available in various sizes (from 20x20 up to 40x40 and beyond), our chambers are modular: you can fit extension rings to reach the depth of your trench and choose between solid covers or gratings depending on whether you want simple inspection or surface drainage. Thanks to their pre-cut knockouts on all four sides, our chambers allow quick, watertight connection of drainage pipes of various diameters. With Jardiboutique, ensure a clean, accessible and long-lasting underground infrastructure.

Jardiboutique's technical advice: A well-installed chamber makes life easier. Installation tip: Always place your chamber on a well-compacted trench base (a bed of sand or lean concrete) to stop it settling over time, which would crack your pipes. Filtration: If you connect your chamber to a soakaway or a rainwater harvesting tank, fit a silt basket inside it. It will hold back sand and small debris before they reach your storage. Maintenance: Check the inside of your chambers once a year, ideally after autumn, to remove any leaves that may have got through the gutter and built up at the bottom.
