Wilcote Port Elizabeth have been awarded the Phase II contract, (after the successful completion of phase I) for the Asbestos Roof Refurbishment at their bottling plant at Coca Cola Lakeside in Port Elizabeth.
The process of refurbishing Asbestos Roofs involves firstly washing the roof down with an Eco Friendly Special Asbestos cleaning chemical in order to remove the algae and lichen growth. Because the process is a “wet process” the chances of releasing asbestos fibres into the air are minimal as we also fit asbestos filters to all rainwater downpipes. The Asbestos Regulations do however require the air to be monitored during this process of washing the roof down. The method of monitoring the air is by fitting air pumps at either end of the roof and one pump is fitted a staff member. The gauze grids on the inside of the pumps are sent to a laboratory for inspection and counting of the number of Asbestos Fibres contained therein.
Once the roof has been thoroughly cleaned down and has dried an Asbestos Encapsulation is applied by Airless Sprayer onto the roof sheets. This process binds any loose Asbestos Fibres which may have been loosened during the cleaning process and then renders the the Roof 100% safe. The roof is then ready to be waterproofed.
The waterproofing layer consists of the application of our Elastomeric Sealer which is applied by airless sprayer at the rate of one square metre per litre. This waterproofing layer effectively seals all hairline cracks, which tend to occur in older asbestos roof sheets and makes the roof waterproof. Because the product is designed to be elastic it expands and contracts with the roof sheets as they heat up and cool down by the ambient weather conditions. Immediately after this layer has been applied the roofing screws are sealed with Wilcote non-hardening Crack and Hole Filler. This product too has very good expansion and retraction properties and, very effectively, seals the roofing screws preventing ingress of any moisture.
The final step of the refurbishment process is the application of the top coat. This top coat is part of our latest Technology Development in Solar Reflection where the infra red rays are reflected back up by the coating. This means that the roof sheets are kept at a cooler temperature than with normal roof coating which in turn means a saving in energy costs.
This whole process is cheaper than replacing the roof with one of the many types of metal roof sheets available and the real plus is that the refurbishment will not interfere with the day to day activities taking place on the inside. If clients were worried by the effects of Asbestos on the staff and businesses these can now be forgotten.
Wilcote offers a guarantee on the above asbestos roof repair system of 12 Years but longer guarantees are available upon request.
