The problem and potential liabilities for properties affected by “mundic” are well known in Cornwall and Devon.
The series of tests approved by the Royal Institution of Chartered Surveyors provide the means of assessing whether mundic is present and an indication of its severity.
In 2002 the Royal Institution of Chartered Surveyors issued a supplement to the 2nd Edition of the Mundic Guidance Notes, outlining a new Stage 3 test for the classification of mundic concrete to supplement the existing Stage 1 and Stage 2 tests.
There are 3 levels of assessment which can be used. Stage 1 and 2 are visual assessments of the compostion and condition of the aggregate in sample cores taken from the property.
Stage 3 is a longer term physical test of the performance of the aggregate under controlled environmental conditions which simulate ageing and weathering.
At each stage samples can pass or fail. Successful completion of a Stage 3 test can in some cases reclassify a previous failure at Stage 2 bringing the subject property back into the mortgage market.
We are able to offer all 3 stages of testing in-house at Wheal Jane and we are the only Company in Cornwall offering a Stage 3 testing service.
