Polystyrene for drainage?

    I've bought a new build house (I know), and the drainage in the back garden is non-existent. I have a very small gravel channel from my drive running under the fence to the patio. I've just dug this away to see if there's a sort of drain under the chippings and all I found was polystyrene amongst all the muck. Does anyone know what purpose this serves or is it bad workmanship?
