Many soils contain clay minerals that absorb water when wet (making them swell), and lose water as they dry (making them shrink). Many of us see this in our gardens when the ground becomes cracked during the summer, yet becomes ‘heavy’ in the winter.

This is a single data layer that identifies areas of potential shrink–swell hazard that are underneath another solid formation and therefore hidden from the surface.

Ground dissolution occurs when water passing through soluble rocks produces underground cavities and cave systems. These cavities reduce support to the ground above and can cause localised collapse of the overlying rocks and deposits.
