This lady knows how to write edge of the seat suspense and Frozen Ground is no exception. You can feel the tension as each page-turning step hurls the reader to the heart-pounding conclusion/5(71).
Artificial ground freezing has been used for over a century to form a temporary support and an impermeable barrier for underground openings and other excavations. Nowadays it can be an efficient barrier to prevent pollution spreading in permeable soils.
The time required to freeze the ground will obviously depend on the capacity of the freezing plant in relation to the volume of ground to be frozen and on the spacing and size of freezing tubes and water content in the grounds.
