Mundic Testing
Has your mortgage lender requested a Mundic Test?
COR Building Surveys Ltd is a RICS Regulated Firm specialising in Mundic Testing and Concrete Screening Reports throughout Cornwall and Devon.
Whether you are purchasing your first home, selling a property, remortgaging, or simply require reassurance regarding the construction of a property, we provide professional Mundic Reports prepared in accordance with the current RICS Guidance for the Inspection and Testing of Concrete Used in Construction in Cornwall and West Devon.
Our reports provide an independent assessment of the concrete used within a property and are prepared for mortgage lenders, solicitors, conveyancers, estate agents, buyers and homeowners. Every inspection is carried out by an experienced Building Surveyor using specialist sampling equipment, with all laboratory analysis undertaken by an independent UKAS-accredited laboratory.
We pride ourselves on providing a professional, friendly and efficient service. Inspections can typically be arranged within a few days, with Mundic Reports normally completed within five working days of the inspection, subject to laboratory turnaround times.
To date, our reports have been accepted by all mainstream mortgage lenders to whom they have been submitted.

What Is Mundic?
Mundic is the term commonly used in Cornwall to describe certain concrete blocks manufactured using aggregates that may be susceptible to deterioration over time.
During the early to mid-twentieth century, locally available materials, including mine waste, quarry spoil and other natural aggregates, were commonly used in the manufacture of concrete blocks throughout Cornwall and parts of Devon. Whilst many properties constructed using these materials remain perfectly sound, some aggregates have been found to deteriorate when exposed to moisture over long periods.
As the condition of the concrete cannot be determined by visual inspection alone, representative core samples are obtained and examined by an independent UKAS-accredited laboratory in accordance with the current RICS Guidance. The laboratory findings are then used to determine the appropriate Mundic classification and assist mortgage lenders in assessing the property's suitability for lending.
How does it work?
Step 1:
We will organise an appointment, generally within a week of being instructed. The surveyor will attend the appointment and drill core samples from all the walls he might consider relevant (internal and external).
Step2:
Samples will be taken to the laboratory to be analysed for the presence of Mundic. The results are usually ready within 48 hours (often quicker).
Step 3:
The surveyor will complete a detailed report meeting the requirements of the RICS Mundic Guidance Note 3rd Edition.
What does my mundic test result mean and how does it affect my mortgage?

-
Class A3: Concrete contains mundic but is unlikely to suffer adverse effects. Stage 3 testing advised to examine how concrete will hold up in the future. Mortgageable
-
Class B: Concrete contains more than 30% of possible problem aggregates, although it appears sound, it could cause potential problems. Unmortgageable
-
Class C1 & C2: Those found to be clearly unsound from examination. Unmortgageable
How much it cost?
