The Astec Asbestos System is one of long term rehabilitation and stabilization. This system does not require high pressure cleaning of the weathered sheet which is now prohibited in Australia. The system utilizes an under-film mould retardant, a penetrating sealer / binder, and highly durable heat reflective elastomeric topcoats. 

The system penetrates and locks firmly deep within the non-decayed asbestos fibre matrix. Splits, fasteners and flashings are waterproofed and reinforced with polyester matt ensuring a long-term water tight roof. It removes the threat of under-film mould re-growth and provides a new impact resistant surface to the weathered sheet. 

The system can be installed at a fraction of the cost of replacement, and without the inconvenience and disruption to business or home life. Astec Energy Star system for asbestos roofing renders the sheet safe, cool and aesthetically pleasing.

The Problem

Over the years asbestos cement roofs deteriorate through weathering.  The surface layer of cement decays, exposing the underlying asbestos fibres to the environment through an ongoing process of erosion.  As a result, the asbestos cement thins, becomes brittle and the structural stability of the roof is greatly reduced.  The material becomes dark, increasing the internal temperature of the roof cavity and lichen growth detracts from the aesthetics of the building.

​

The solution

The Astec Asbestos Restoration System penetrates the non decayed asbestos fibre matrix thus restoring the sheet to a near new strength of 2.1 mpa.  Removal and replacement of the asbestos sheeting is a costly, unnecessary and disruptive exercise.  In contrast, the Astec system is fast to install, less expensive and encapsulates the asbestos fibres.  This provides a roof that; is stronger, safer, more stable, aesthetically pleasing and remains cool in the extremes of summer.
