Building Defects Investigation.


Building defect investigations are not only required when problems occur but also when assurance is needed that defects do not exist or that the building standard is such that problems are unlikely. KEM has considerable experience in this type of work and in addition to the usual techniques of
building defect investigation offers a comprehensive range of state of the art technology including thermography analysis and metal detecting and pipe tracing. KEM’s expertise and experience in this field means that it can offer a wide ranging array of investigative techniques which include.


Identifying Thermal Bridges… A thermal bridge is created when materials that are poor thermal insulators come into contact, allowing heat to flow through the heated space to the outside. Typical effects of thermal bridges are decreased interior surface temperatures (which can result in condensation problems, especially at corners), significantly increased
heat losses and cold areas in buildings)




Flooring Defects… Using a vast array of techniques and testing applications KEM are able to test the integrity of virtually any flooring. These methods can vary from logging relative humidity readings to material composition testing and in some instances a full laboratory
micro analysis.




Insulation Continuity…Defective or missing insulation can cause unnecessary heat loss, can create condensation, mould problems and make living spaces thermally uncomfortable.

By using infra-red inspection KEM can quickly and easily identify problem areas causing no damage and minimal disruption. Anomalies which are identified can then be inspected by Borescope and against construction details. Thermal bridges can be design features such as flue ducting etc…



Identify Areas Of Defective Render… In some cases defective render can lead to damp and deterioration of the underlying wall. The use of a thermal imaging camera will detect all areas of damp or loose materials. By adopting this technique KEM are able to facilitate fast and accurate repair work, making this process extremely cost effective and preventing further structural damage.




Water Ingress….Moisture problems can occur in properties for a number of reasons. These can range from a leak from a central heating pipe to a major construction defect. The expertise that KEM has in this type of investigation allows us to utilise a collection of non-destructive and traditional testing methods in order to identify the source accurately with minimal cost, damage and disruption.




Damp Investigation….Damp and water leak investigation often require a wide range of inspection and testing techniques. KEM are able to select the most appropriate technique or combination of techniques in order to eradicate damp or water ingress problems which may include: Thermal (infra-red imaging), Acoustic testing, Water Analysis, Damp meter surveys, Materials sampling and analysis, Tracer gas testing, Borescope investigation and Correlation.




Evaluate and Verify Repair Work….Thermal imaging can be an extremely useful tool in conducting both pre and post repair inspections. This method can assist in precise documentation of works and can accurately pinpoint treatment sites that are unable to be seen by the naked eye saving time and money. As with other applications of thermal imaging, this is non-invasive and very cost efficient.




Predictive Maintenance…This can improve the performance reliability of building elements and whole buildings by avoiding any potential problems that may cause unscheduled downtime or degradation of performance. KEM’s most frequently employed predictive maintenance technique is the survey survey of building fabric in order to identify moisture ingress/egress, particularly on flat roofs.
