Jointing compound

[jones2004]

I want to extend a tarmac path and would like to use a jointing compund between the old and the new. Is there a tape like the ones you can get for yellow lines which you can just place over the joint and heat to adhere to the old and new tarmac as I find using liquid bitumen untidy.

None that I'm aware of. If there is one, it'd probably be a Colas product. Check their website.

You could always try masking off the joint and then apply the cold pour jointing compound.

Ive found it!! burdens supply a bitumen tape which you place over the joint and heat up to seal.

Thanks for your help

Have you got a reference for it? I was speaking with Burdens sales manager only yesterday - although we were actually discussing geo-technical applications.

I never thought to ask for a reference number but i spoke to burdens, warrington. Ill ring them again tomorrow for ref and ill post it.

Ask them to send the details to me here in Culcheth (Warrington is a small village on the outskirts of Culcheth.) Tell them Adi Day in Bristol will OK it, if there's any problem.

Its called overbanding tape, it come in 10m lengths, 30 - 50mm wide and 2 - 4mm thick.

No reference number.

Ive contacted denso to get product and application info but their product is for cold lay.

Denso! I should've known! We've used that dozens of times and for some reason my mind went blank.

Funnily enough we found an unopened roll of Denso on one of John Higgins's jobs in Widnes last week!

So what do you think of the stuff is it worth using??

[Tony McC]

Yes - it's vastly more expensive than cold pour, which is why it's rarely used for commercial projects, but it is a lot neater.
