Cob repairs are oftentimes required to corners of cob buildings, particularly window and door reveals. These areas tend to be vulnerable to weather erosion and/or disruption. Many old cob buildings have had replacement windows and doors introduced at some stage, therefore it is inevitable that some disruption would have occurred. In addition, many cob walls have had hard, impermeable renders/plasters applied, common-most are cementitious applications.
There is clear evidence that our understanding of historic fabrics is gaining momentum and the preservation of ancient cob walls continues to attract [much welcome} attention.
Removal of hard, inappropriate cladding/s such as cement-based products should be considered carefully and executed proficiently because this is where more harm than good is likely to occur if not done properly. So, with all best intentions it may be that removal of such claddings has caused [minimal] disturbance to the corners or reveals…..we can now take-up the story of our rounded cob products.
