|Prior to demolition services, many facilities require environmental abatement which can include the removal of asbestos, vermiculite, PCBs, mould or various other contaminated materials.
The abatement process involves various stages to ensure the safe removal and disposal of the toxic materials. ProGreen is well versed in the removal procedures and has safely completed hundreds of abatement projects across Ontario in vacant and occupied residential, commercial, industrial and institutional buildings.
Asbestos, a mined material, became popular in construction because it was an effective reinforcing, insulating and fireproofing material. It was used as insulation board, asbestos cement and floor and ceiling tiles until the 1970s when it was discovered that if significant quantities of asbestos fibres are inhaled it can cause asbestosis, mesothelioma and lung cancer.
Vermiculite, a mined mica-like mineral, was commonly used in attic insulation until the 1990s because of its effective fire-resistant and insulation qualities. Some vermiculite insulation may contain asbestos fibres that can cause health issues if disturbed during renovation or demolition.
Polychlorinated biphenyls (PCBs) can be found in a number of products including some older caulking compounds, paints, coolants, lubricants, and electrical equipment. Although banned throughout North America in 1977, PCBs are bioaccumulative and do not easily break down. They persist in the environment for long periods of time and are transferred up the food chain to other living organisms. (Health Canada)
