U-DRAINS
Open-channel precast drainage for roads and open areas. Four sections, a manhole option, and matching reinforced cover slabs.
Also on this page: U-Drain Cover Slabs
U-drain sections are supplied with matching cover slabs. Pick the internal section, say whether you need access chambers, and the quantity in running metres.
Concrete grade and load class are specified against your project and confirmed on the quotation, so we do not publish a single figure here.
