I've used thin correx on my C&C and just put loads of strong gaffer tape on the corners (around & underneath) and it seems to have worked.
I put a thick layer of newspaper down first and then I use Walmsley Premierbed card bedding
http://www.walmsleypremierbed.co.uk/ on top, which I've personally found to be the best for my 5 boys after trying a few different types of bedding. I'm lucky that I don't live too far from their place & I can buy direct from them at £5.50 for a 20kg bag but I think it's about £6 at other stockists.
I do a whole cage clean about 5-7 days but I spot clean their sleeping/poopie soiled areas every day. Putting an extra bit of newspaper under their hideys means you can just lift up that bit with all the mess on & just replace that area with fresh bedding. I hope you find a solution that suits both you and your piggies soon.
