Hazardous Substances and Remediation

Moulds have increasingly become a problem inside buildings. The reasons for which include structural defects and a change in building design with significantly denser exterior components which inhibit air circulation. Moreover, heating and ventilating habits favour the spread of moisture-loving organisms.

National- and EU-guidelines increasingly emphasise responsibility for room air quality and the measurement of hazardous substances. Depending on the type of issue, WESSLING carries out sampling in buildings by collecting airborne germs and particulates and comparing the results with outside air measurements, and also by taking surface contact samples (wipe or tape lift) or material samples. This serves to identify hidden mould infestations. If the results are positive, our specialists will help you plan and supervise the remediation of your building.

Our services:

• Investigations into microbial contamination and measurement, e.g. building moisture
• Detecting mould spores and germs in room air and material
• Supporting and supervising remediation measures

Here you find further information on our comprehensive range of services in the field of air monitoring and measuring stations as well as building products.

Our engineers begin with an inspection of the building, immediately identifying the building moisture itself, potential mould infestation and, above all, their technical causes. Based on our long-standing experience, we propose solutions for eliminating the causes and drying the affected area.

These are based on a thermal insulation calculation, for which we determine wall thicknesses, normal wall moisture levels, construction characteristics and materials.

Our services:

• Building inspections by qualified specialists
• Identification of construction details and recording of measurements
• Professional analysis and electronic evaluation
• Independent and reliable statements

In addition to the Blue Angel label and the GEV EMICODE, the AgBB scheme should be mentioned as the most important German test (the AgBB is the Committee for Health-related Evaluation of Building Products). When  a building is accepted following room air monitoring tests, the success of the selected materials and product checks – if necessary completed by energy saving data – can be documented for you in a certificate.

WESSLING has a very well-equipped laboratory with test chambers of various sizes ranging from 110 litres to 20 cubic metres. Our range of test chambers covers both the relevant products and the test methods.

Our services:

• Test chamber analyses in accordance with DIN EN ISO 16000-9,11; DIN EN 16516
• Emission tests:
  • of building products according to the AgBB scheme
  • for restricting emission sources (VOCs, formaldehyde, odour, PCB)
  • on electrical appliances
• Quality seal
