Vermiculite Removal

What is vermiculite:

Vermiculite RemovalVermiculite is a lightweight mineral mined in several locations around the world. It was used in insulation and other products because of its fire-resistant and insulation properties.

Products made from the W.R.GRACE Libby Mine in Montana (under the brand name Zonolite) are known to contain amphibole asbestos. W.R. Grace marketed and sold their products within many Ontario homes. Laboratory testing, which we offer, is the only effective method of determining  if your vermiculite contains asbestos.

Tremolite asbestos is the particular type of asbestos found in this vermiculite and is considered the most dangerous to inhale.

WHERE DO WE FIND VERMICULITE IN DWELLINGS?

Vermiculite was used for over a century. Some vermiculite contains no asbestos, however it has been our experience that zonolite was the most popular.  Attics, knee walls and double brick/cinder block walls may have insulation poured into the cavities. It may be buried under other levels of insulation.

WHAT TO DO IF YOU’RE PLANNING TO ALTER, DEMO or RENOVATE AND YOU SUSPECT VERMICULITE IN YOUR DWELLING:

Call us to extract required samples (most attics need three). We send these samples to an accredited laboratory before you start. Asbestos concentrations are not homogenous in vermiculite; percentages can vary however the Ministry of Labour of Ontario considers any concentration above .05 to be a concern.

WHAT TO DO IF IT’S POSITIVE:

  1. Call us to make a proposal for proper professional extraction and installation of new insulation
  2. Do not disturb it by yourself

WHY EXTRACT?

  1. When you go to sell your house, professional home inspectors will find it and your property will be devalued.
  2. Insurance and Bank corporations find this to be a risk and may charge a premium or refuse your business
  3. Under regulation 278/05 any employee has the right to refuse work without consequences if they feel they will be exposed
