Concrete drain repair

onejontwo

I have just discovered what appears to be a hairline crack in the concrete drain outside the kitchen, I was wondering if there was any way of repairing this ie. mortar, waterproof paint etc. that would last without replacing the whole drain?
I don't know if the crack goes right through as there doesn't seem to be any way of testing so I thought I'd play safe and attempt to repair it.
Thanks in anticipation.

Do you mean drain or do you mean gully?

Pic?

Here we go then:- The crack is on the left hand side, almost all the way across from top to bottom.

It's not a major fault. I would be inclined to clean any loose paint or coating off and give it a coat of Aquaseal.

Nothing to worry about.

Thanks for the reply, I've googled "Aquaseal" and there appears to be a lot of different types on the market, any chance of a link to which one would suit?
Cheers.

If you are not bothered about the appearance you could run a bead of silicone over the crack, be it clear silicone or coloured.

If it was my gulley I would not be worried by it.

Frost is the only item that comes to mind, but it is probable the crack has existed for years and not caused a problem. It is also probable on such a fine crack no water is penetrating it. Indeed, salts and debris may have effectively sealed the crack - not making it watertight, but good enough.

Clean it up and use a runny mix of quick setting cement, such as Jetcem, and run it into the crack, and as it cures you can level it out and point it into the vertical cracks?

Be quick though as it cures extremely quickly?

May be advisable to mix in a little fine sand as it assists with shrinkage!

On second thoughts if a thorough repair is required, open up the crack ever so slightly,or groove along it. Then use "Sticks Like..." This will stick anything to anything, even if the items are wet - such as a gulley hopper.

[IMG][/IMG]Thanks for all the replies, one last thing before I set about repairing the crack, I've noticed that some of the tarmac surround is crumbling away. Also the gulley doesn't sit true ie. it's tilted at an angle. What does the gulley actually sit on and what would you recommend as a repair ie patch tarmac or dig up and start what appears to be a major job?[IMG][/img]

Hi

I'd be more worried about the poor pointing on the brickwork. Also it looks like the smaller pipe is flowing over the edge of the gulley, this is probably causing the damage to the Tarmac.
