Alumasc’s Derbigum Olivine roofing membrane is a highly effective, durable waterproofing solution which also purifies the air - helping combat global warming by neutralising the most prevalent greenhouse gas, CO2.
When rainwater comes into contact with the olivine, an irreversible chemical reaction washes the CO2 out of the air by transforming it into three environmentally-harmless substances: water, magnesium carbonate and sand
Whilst other so-called ‘environmentally friendly’ membranes incorporate titanium dioxide and require sulphuric acid or chlorine gas in their manufacture, the olivine in Alumasc’s Derbigum Olivine surfacing is 100% naturally occurring and simply requires grinding to the right size.
More than 20 million m2 of Alumasc’s Derbigum have been installed in the UK, including the Shard and Canary Wharf.
Alumasc’s Derbigum Olivine is very hard-wearing and is the only bituminous membrane with a 40-year BBA durability statement.
