Alumasc’s Derbigum Olivine Cleans the Air

Alumasc’s Derbigum Olivine roofing membrane is a highly effective, durable waterproofing solution which also actively purifies the air and makes a positive contribution towards reducing global warming.

When rainwater comes into contact with the Olivine an irreversible chemical reaction takes place which transforms CO2, the most prevalent greenhouse gas, into three environmentally-harmless substances -water, magnesium carbonate and sand - and literally washes it out of the air.

Whilst other so-called ‘environmentally friendly’ membranes incorporate titanium dioxide and require either sulphuric acid or chlorine gas in their production, the Olivine in Alumasc’s Derbigum Olivine surfacing is 100% naturally occurring and simply requires grinding down to the right size.

More than 20 million square metres of Alumasc’s Derbigum, which is very hard-wearing and the only bituminous membrane with a 40-year BBA durability statement - have been installed in the UK, including on the Shard and in Canary Wharf.

Olivine is completely UV resistant, meaning that its effectiveness is not degraded by the sun’s rays. Even with natural ageing, the active compound of the olivine will still be present when the roofing membrane itself is at the end of its lifespan.
