Asbestos Refurbishment & Demolition Surveys

Asbestos Testing

As one of the most feared industrial materials, asbestos continues to grip international headlines. Regulatory demands, and their scrutiny for compliance, makes asbestos testing, monitoring and disposal essential for all organisations and property owners who wish to meet their responsibilities.

If you are planning a renovation or a demolition, it is important that you carry out an Asbestos Refurbishment and Demolition Survey (R&D) in line with the NZ Health & Safety at Work 2016 Regulations. This is more invasive than a Management Survey and involves surveying all areas that will be damaged or removed during the course of works. Xava can also carry out single sample testing and analysis in a case where you may be removing a single material, such as a textured coating or floor lino.


  1. Asbestos Cement Products
  2. Textured Coatings
  3. Floor Tiles, Textiles & Composites
  4. Sprayed coatings on walls, beams/columns
  5. Asbestos insulating board
  6. Lagging
  7. Loose Asbestos in ceiling or floor cavity


You can’t identify items that may contain asbestos simply by looking at them. The only way to confirm the presence of asbestos is to take more than one sample of the material and have it tested by an accredited asbestos laboratory. If you suspect asbestos, the safest approach is to treat the material as if it does contain asbestos.


Your first step should be to obtain samples of the suspected material and have it analysed at an accredited asbestos laboratory. The number of samples required to prove non-asbestos is regulated. We can conduct assessments of all sample materials using state of the art technology in order to detect and identify the presence of asbestos. Our survey team ensures all asbestos testing is conducted in accordance with national and international regulations and standards. We assist you by taking full responsibility for isolating, identifying and quantifying all material types.


Asbestos used to be so cheap, available, and accessible that it is hard to find an asbestos-free construction material. Besides being a common component of construction materials, asbestos was also used in materials like technical canvases, automotive parts, cardboard, laboratory equipment, heating home appliances, and many more. By now, all those asbestos-containing items are no longer in production but can still be found in older buildings, or, to be more precise, the construction materials of those buildings.

For your reference, we include an incomplete list of the most common sources of asbestos in the house. Please note that only a laboratory test can show whether a certain material contains or does not contain asbestos.

  • Transite pipes – cement-like pipes, they are usually grey in colour with a rough surface. Were used as heavy-duty cement pipes.
  • Transite boards – asbestos–cement boards, and corrugated boards. They have texture and colour similar to transite pipes above. Flat panels were used as water and weather resistant material. Corrugated panels were used as a common roofing material.
  • Vermiculite attic insulation – this insulation may contain traces of asbestos, usually between o.1 -to 2%.
  • Insulation for pipes and boilers, pipe wrap (fabric), and mastic (glue)- all three components may contain asbestos.
  • Vinyl floor tiles, underlay, and adhesive – asbestos was used on all three materials multiple layers of tiles
  • Textured ceiling paint (popcorn ceiling)
  • Ceiling tiles
  • Millboards
  • Insulation boards in cores and lining of composite products
  • Putties, caulks
  • Bitumen products
  • Joint compound

If you suspect that your house is contaminated with asbestos, bring a sample of the suspected material to our offices for analysis or contact us to collect your sample. We will test your samples and send you a formal, detailed report.

      Do you own or manage a commercial building? The Health & Safety at work regulations were updated in 2016, meaning it is now a legal requirement to have an asbestos Management Plan in place.
