Concrete testing is undertaken by our Cornwall Office (covering mid/western areas of the County) in accordance with the current RICS guidance note. Throughout Cornwall concrete of prior to 1950 in origin (1965 in some areas of north Cornwall and Devon) will need to be tested to make sure the material is sound and not deteriorating. Poor concrete is known locally as ‘Mundic’ and is usually the result of the concrete being made from mine waste that is rich in sulphide materials and in particular pyrite (frequently known as ‘fools gold’).
If the concrete is poor this will affect the value and mortgageability of a property. It is very important the risks are established prior to legal commitment to purchase (exchange of contracts) so you can make sure your proposed new home is free from any significant ‘Mundic’ problem.
Core drilling is used to extract concrete samples before they are examined petrographically.
