Metro Industrial Roof Restoration are the number one installer of the Fibroseal asbestos encapsulation system in Australia, and have the full and complete backing of the system manufacturer Crommelin, to assess, specify and carry out asbestos encapsulation roof treatment installations throughout Australia.

Asbestos cement sheeting undergoes a weathering process after many years of exposure and a loose surface layer develops which, on roofs becomes colonised with dark coloured lichen. The lichen, secreting oxalic acid, attacks the cement, causing exposure of the asbestos fibre. The surface becomes unstable, the asbestos cement sheeting is weakened and the darkened colour causes a substantial increase in roof cavity temperatures.

The unstable nature of weathered asbestos cement surfaces is a cause of some concern in the community as white and blue asbestos fibres were used in the composition of asbestos cement sheeting. In the 1980's the use of asbestos was discontinued in the production of fibre reinforced cement sheeting, but the ageing existing roofs continue to deteriorate.

Asbestos Roof Treatment

The Problem
The traditional process for treating asbestos cement roofs was to firstly clean the roof with high-pressure water to remove all lichen and loose asbestos fibre. This procedure however was banned on health grounds, creating a need for a system which could be applied straight to the degraded asbestos without disturbing the surface.

The Solution
In 1990, our suppliers, Crommelin set out to address this problem and developed The Fibroseal System for the treatment and encapsulation of asbestos roofs. The Fibroseal System achieves the following:

  • 1. To bind and encapsulate the asbestos fibres.
  • 2. Avoids costly downtime associated with replacement of asbestos.
  • 3. A significant reduction in roof cavity temperatures resulting in savings in building cooling costs.
  • 4. An extension of the service life of asbestos structures.
  • 5. A completely water-based and truly environmentally friendly system.
  • 6. Provides a rejuvenated appearance in a range of decorative colours.

Australian Government Approval

The Fibroseal System has had an A.P.A.S. Approval certificate, number 1720/2 since 1990, the longest held approved system for the specific use to encapsulate asbestos roofs. A.P.A.S, formerly the Government Paint Committee Approval GPC-C-1720/2 Scheme, is administered by the C.S.I.R.O and complies with AS/NZS 900:2000 Standards.

Savings in Building Cooling Costs

On untreated weathered asbestos roofs, roof cavity temperatures can rise to double the ambient shade temperature.

When the asbestos roof is treated with the white Fibroseal System there is an approximate 80% reduction in roof cavity temperatures when compared to untreated weathered asbestos roofs.

This temperature reduction results in improved comfort for the occupants and considerable savings in building cooling costs.

Applying The Fibroseal Asbestos Encapsulation Roof Coating

The Fibroseal Asbestos Encapsulation System

The Fibroseal System consists of two products:

a. Fibroseal Primer
A clear one pack, water based, low viscosity, highly penetrating solution that soaks through the lichen and degraded asbestos cement, down to the sound base material binding these unstable elements.

b. Fibroseal Topcoat
A high solids elastomeric membrane providing a long-term protection to the encapsulated layers, whilst providing heat reflective and aesthetic properties. The system has excellent resistance to dirt pick up and provides resistance to the re-growth of moulds and lichens.
