Building Defect investigation
Missing or defective insulation causes unnecessary heat loss, can cause condensation / mould problems, and make living spaces thermally uncomfortable. Infra-red inspection can quickly and easily identify problem areas with no damage and minimal disruption. Anomolies identified can be investigated by borescope and against construction details – thermal bridges can be design features such as flue ducting etc.
Identifying Thermal Bridges
A Thermal Bridge is a thermally conductive material which penetrates or bypasses an insulation system; such as a metal fastener, concrete beam, slab or column. Heat will flow the easiest path from the heated space to the outside – the path with the least resistance. Very often heat will “short circuit” through an element which has a much higher conductivity than surrounding material, which can be described as a thermal bridge. Typical effects of thermal bridges are decreased interior surface temperatures (this can result condensation problems, particularly at corners), significantly increased heat losses and cold areas in buildings
Identify Areas of Defective Render
Defective render can lead to damp and deterioration of the underlying wall. A thermal imaging camera will detect areas of damp or loose materials, facilitating fast and accurate repair work. This process is extremely cost-effective and prevents further structural damage
KEM can test the integrity of virtually any floor using a vast array of techniques and testing applications this can vary from logging relative humidity readings, to material composition testing, and in some cases a full laboratory micro analysis.
Moisture problems can appear in properties for a wide number of reasons. These can range from a central heating pipe leak to a major construction defect. KEM’s expertise allows us to use a collection of non destructive and traditional testing methods to diagnose the source correctly with minimal, cost, damage and disruption.
Damp and water leak investigations often require a range of inspection and test techniques. KEM select the suitable technique or combination of techniques to solve water ingress and dampness problems, which may include:
1. Thermal (Infra-red imaging)
2. Damp meter surveys
3. Acoustic tests to identify / rule out pipe leaks
4. Water Analysis to indicate / eliminate potential sources
5. Materials Sampling & Analysis to confirm indicate / eliminate potential sources
6. Borescope investigation of out of site / hard to reach areas
7. Tracer gas testing of pipes to pin-point leak locations
Predictive maintenance can improve the performance reliability of building elements and whole buildings by avoiding potential problems that may cause unscheduled downtime or performance degradation.
KEM’s most frequently employed predictive maintenance technique is surveys of building fabric to identify moisture ingress / egress, particularly on flat roofs.
Evaluate and Verify Repair Work
Thermal imaging can be a useful tool in conducting both pre- and post-repair inspections. Thermography assists in accurate documentation of works and efficiently pinpoints treatment sites that are not visible to the naked eye, saving both time and money. As with other applications of thermal imaging, this is non-invasive and extremely cost effective.
