I've got a nice sized play pen for the piggies which they seem to love

What should I use for the flooring? I've tried newspaper but you have to use 3-4 thicknesses to stop the urine soaking through which by then there's a couple of newspapers down which gets all messy.
Is there any other flooring for the playpen to stop them damaging the carpet and is easy to clean and pack up?
Thanks
