English Cob Buildings
Cob is still successful and being sustainable, it is an effective material for construction. Without proper maintenance, cob walls will develop cracks and holes resulting in vermin and erosion. Cement render is very deceiving and often surveyors and homeowners do not realise that the wall is actually made from cob.
Dips and hollows in the Cob surface is often the result of water damage. To carry the forces acting from above, repairs should be made up in horizontal layers which can be done by making cob blocks. The blocks can be bedded in an earth mortar made from sub soil. A sticky mortar is formed after the earth has been sieved to remove larger stones and been mixed with water. This then gives the blocks good bedding. |
