Asbestos Removal in South Africa
On 28 March 2008, South-Africa banned the use of asbestos.
Thousands of houses, warehouses, factory buildings and office buildings are constructed with asbestos sheeting and other asbestos based or containing products.
Many of these sheets are damaged and the risk of airborne asbestos fibre is increasing all the time.
Additionally, worn and weathered asbestos can result in a loose friable surface that can expose the harmful asbestos fibres.
Regulation 15(1)(h) states “An employer or self-employed person who erect, maintain, alter, renovate, repair, dismantle, or add asbestos-cement roof sheeting, wall panelling, gutters, fascia boards and related products to a building shall ensure that-once installed and where reasonably practical, the relevant items are painted or otherwise sealed with a protective coating to limit the release of asbestos dust, combat weathering and inhibit growth of lichen or moss"
The Safe Alternative to Asbestos Removal
Asbestos must be “Encapsulated” according to Regulation 15(1)(h)
Painting the asbestos surface with roof coating or other paint is not a solution.
- - Roof paint doesn’t strengthen the underlying asbestos sheets.
- - Inconsistencies in paint application is a major problem
- - The lifespan of roof paint is short.
- - Paint can flake and the asbestos sheeting can still crack.
Asbestos Encapsulation should preferably be done with polyurethane spray foam (SPF).
The Benefits of Spray Polyurethane Foam for Asbestos Encapsulation
- - Cheaper than removing sheets
- - Closed cell polyurethane spray foam is applied to both sides of the asbestos sheet completely encapsulating the asbestos
- - Additionally, SPF provides seamless waterproofing
- - Furthermore, SPF offers building's thermal insulation
- - Production can continue if externally applied only
- - Moreover, SPF strengthens the roofing structure repairing damaged asbestos sheeting
How Durable is 'SPF'?
Roofs with 'SPF' insulation have lasted well over 30 years in places like the US, where the technology was first implemented, but should last as long as the building itself.
Buildings with SPF Roofs, have superior performance in severe weather, this was seen during events like Hurricane Katrina.
Not only is the 'SPF' Material itself extremely durable, but it also protects and preserves the building components it covers.
Encapsulation with closed cell polyurethane foam completely removes the hazards of asbestos fibres and dust.
Using this technique will ensure a healthy as well as an asbestos dust free environment.
