Shrink / Swell Susceptible Geology

Those geological deposits that are most likely to shrink and swell are well known and mostly occur in south east UK.

The main hazardous shrink/swell geological formations are:

 

  • London Clay Formation, (generally not in the Dorset, Hampshire and Sussex)

 

  • Gault Formation,

 

To a lesser extent:

 

  • Fullerís Earth Formation

 

  • Oxford Clay Formation,

 

  • Kimmeridge Clay Formation

 

  • Weald Clay

 

The London Clay and Gault formations are both found in south east this is also the area most likely to droughts. The London Clay Formation in the Hampshire Basin is less susceptible.
