Historically the cost of providing access formed a disproportionate part of the total cost of many inspection and minor repair operations. The introduction of the industrial rope techniques (abseiling) leaves few surfaces which cannot be quickly and cheaply accessed for inspection, testing and maintenance purposes.
The full scope of Special Inspection testing for corrosion risk assessment by half-cell potential, cover, resistivity measurements and chloride analysis is undertaken by Sandberg who have established in-depth expertise and experience in this work. Other tests for strength, composition and alkali reactivity are also undertaken.
When buying or leasing property, prospective owners and tenants need to be confident that any future commitment to the property is not a potentially disastrous financial time bomb. In this regard, surveyors and structural engineers offer services that can identify impending problems with the building.
The exterior facades of many modern buildings are constructed from numerous component parts. These components may have been installed on site or assembled in a factory to form a cladding unit. Recent building designs have been tailored to achieve some stunning appearances using an ever increasing variety of materials; but coupled with such diversity comes the potential for problems associated with design, workmanship, durability of materials and security of fixings.
Floors are an important operational component of industrial buildings. However, concrete floors can often be a source of problems both during construction and subsequently during service. Cracking, staining, poor abrasion resistance, chemical attack and other defects have all been observed in recently constructed buildings.
Concrete has good fire resistance and concrete structures generally perform well. However, the visual appearance of concrete after a fire can be quite shocking with extensive blackening often accompanied by spalling and cracking. Of more importance, though, is the depth and extent of the fire damage.
Glass Fibre Reinforced Concrete (GFRC) utilises high strength glass fibres to replace traditional forms of reinforcement thus producing a unit that can be up to 75% lighter than conventional precast concrete units. Sandberg can assist with consultancy services relating to the procurement of Glass Fibre Reinforced Concrete (GFRC) and the subsequent inspection of the manufactured products both in the UK and worldwide.
HAC differs from Portland cement, being composed of calcium aluminates rather than calcium silicates. Its rapid strength development made HAC popular for precast concrete in the UK during the 1960s. Mineralogical ‘conversion' however, sometimes caused catastrophic reductions in concrete strength and increased vulnerability to chemical degradation.
Paint inspections undertaken by our experienced paint inspectors can help identify the cause of why the large majority of industrial paint and protective treatment failures occur, whether it be due to an inappropriate coating system being specified or through poor workmanship. Through our UKAS accredited laboratories, consultants, engineers and inspectors, Sandberg are able to provide a comprehensive service covering everything from Paint Inspection to Corrosion Surveys to Inspection and Testing of Galvanizing.
Sandberg’s team of experienced precast concrete Inspectors and Consultants are able to assist with all aspects of the manufacturing process for precast concrete units. From permanent formwork to glued segmental construction, Sandberg precast concrete inspection input gives confidence that the product will be manufactured as the Client intended.
Woodwool is a man-made board material about 50 to 75mm thick comprising shredded timber bound together in a cement paste. It was used generally during the 1960s to provide insulation often at roof level and as a permanent shutter to in-situ concrete. Unfortunately, when woodwool was incorporated as a permanent shutter inadequate compaction of the concrete could occur due to...
