    The drain at the end of our driveway is damaged. The supporting half pipe that the drain stands on is broken in places, see sample in picture. What is this drain so I can look at buying a length to replace the broken section? Thanks!

    Its called drainage channel but your issue will be finding some that matches the stuff you have got already in terms of dimensions.
    It may be that to get a decent finish you will have to replace them all.

    Its not cheap for D400 class stuff, plastic is cheap but it depends on the loads it will be subjected to.

    I think I'd try a repair mortar and see if I could rebuild the sides of the old channel.

    Doubt it would work but plan B would be to put another pipe inside the damaged section so it helped support the steel grate on top and then infill the sides with repair concrete then drill holes in the pipe where needed through the holes in the grate. No matter really if the pipe doesn't support the grill as an inch of repair cement over it would probably not harm.

    Thanks, great to learn the terminology. Standard passenger car load typically. Non D400 wouldn't be up to then even a once off delivery of clay or something?

    Had thought about mortar repair. On the right / up side is paving stones that are bedded in sand and I don;t necessarily want to mortar to them when repairing the side wall, I guess some lining or other could be used as a separator. The tops edges of the pipe support the grill. In terms of drilling holes, I'm not sure I understand your solution, are you suggesting for repair to fill the broken section entirely with mortar and then drill holes in it?

    What about a thick piece of metal. Have the dimensions and go to a steelworks place to see if they can make it for you.

    I really don't know if it would work or if its legal for the drainage. Maybe you'd have to paint/seal it before fitting it.

    Idk. Just a though
