About MarshallsAbout keyboard_arrow_left
Excavation depths can be limited when services are positioned close to the surface or where sub-soil drainage would be impeded. Low profile drainage channels can solve such issues and provide effective water management for your project.
Marshalls' Birco Shallow Linear Drainage System is an ideal option. It prevents the risk of any interference with underground services while also reducing excavation costs. Offering a low to medium capacity, it is available in three widths.
Birco Shallow is compatible with a wide selection of gratings, outfalls and covers from the Birco range. Use of the appropriate grating can achieve loads of up to F900
