When can I find goretex type fabric patch?

Evening all,

This may not be the right place to ask but its the closest I could find.

I've got a par of waterpoof offroad motorcycle trousers that on their first trip out must have made contact with the exhaust when I was picking the bike up or pushing it and now have a non waterproof hole in them.

I have found a few different tapes and patches but they are all too small. They tend to be about 5 or 7.5 cm wide, but I need more like 15cmx10cm. If I can't find anything that would cover it all I have to over lap a couple of pieces but obviously one piece would be better.

I found one tape that said it was a permanent repair so thats the kind of thing I'm after.

Any pointers in the right direction would be great.

Cheers

The biggest one in thats pack is 10cm x 5cm so about a 1/3 of the size I'd need. It's starnge how theres nothing bigger. I think I may just have to Use a few and layer them together.
