Flexi Pit

The Flexi Pit is a rail track drainage catch pit comprising an empty chamber with an inlet pipe and an outlet pipe set at a level above the floor of the pit. Any sediment carried by the system settles out whilst in the catch pit, from where it can be periodically pumped out or removed.

Inlet positions on the chamber can be adjusted up to 150mm vertical height to allow for varying invert levels on site. The back-fill board comes in two sizes to accomodate different pipe sizes – 150mm and 225mm; 300mm and 375mm.

It is available  as straight through, tee junction, right hand turn, left hand turn and end of line versions to suit the drainage system design.
