Cob Condition Reports

Although some properties can be constructed solely of cob, it is more common place to find a combination of stone and cob. In these instances masonry will be often confined to a low level plinth ( acting as a base for the cob ) and for use in forming chimney breasts.

Cob is a earthen subsoil with is often excavated locally and mixed with water, straw and horse hair. Walls are built in a series of 'lifts' which are 'squared up' with a cutting tool once the walls are at the required height.

Cob was widely used throughout Devon and Cornwall until approximately 100 years ago and the considerable number of properties still in use is a testimony to its longevity. It is however prone to problems if it becomes damp due to failures in exterior renders or roof coverings.
