- Do sada su se građevinski objeki štitili od podzemnih voda izradom drenaža ispunjenih prirodnim mineralnim tvorevinama kao što su pesak, šljunak, kamena drobina, lomljen kamen, itd. U novije vreme se drenažne ispune rade od sintetičkih plastičnih materijala.
- Until nowadays, the facilities in question have been protected from ground waters by drainages made of natural mineral materials such as sand, gravel, stone debris, crushed stone, etc. In the recent time, the drainage infillings are made of synthetic plastic materials.

The upper "fossiliferous fissure fills" contain clay in addition to limestone debris that has yielded assemblages of partially pyritized organic material including peat, seeds, tree trunks, ostrocods, mammalian bones and freshwater molluscs.

The source of the lime is a bit of a mystery; it may derive from a significant proportion of limestone debris within the glacial till, or alternatively from bands of limestone and calcareous mudstone within the main shale succession.
