With architects and specifiers under pressure to significantly reduce carbon emissions through sustainable building solutions, green roofs have risen in popularity and are seen as a having a significant effect on a building’s sustainable credentials.  Whether intensive or extensive, biodiverse or brown, it’s absolutely critical that green roofs are built on a solid waterproofing foundation.  Offering immense durability and outstanding green credentials, mastic asphalt is the logical choice for specifiers looking for an eco-friendly waterproofing solution for their roof top gardens.

Recognised for its environmental credentials and good looks, a green roof system laid with a mastic asphalt waterproofing system, enhances the environment, controls storm water run-off and reduces noise and heat transmissions by upgrading the acoustic and thermal performance of a roof.

When contractors use mastic asphalt for a green roof system, it eliminates the need for root barriers, which would have been necessary had a substitute material been used.  Alternative membranes to mastic asphalt are more prone to site damage leading to potentially catastrophic and expensive leaks.

One of the most cost-effective, long term waterproofing membranes of its kind, it’s hardly surprising that mastic asphalt is being positively encouraged as THE solution to all green roof and other waterproofing applications. In the unlikely event of a failure, its seamless structure means it can easily be spot repaired, eliminating the need for costly wholesale replacement.

A totally recyclable material, mastic asphalt has other green credentials.  The Mastic Asphalt Councils only manufacturing member IKO PLC sets the precedent for others to follow by achieving the CarbonZero standard – the first time a whole industry has managed such a feat.

This means the world-beating waterproofing solution can be specified on any green project, safe in the knowledge it will minimise the threat of climate change and tough enough to take any green roof design.

Such is the reliability and integrity of mastic asphalt, that many architects specifying waterproofing membranes for a wide range of green roof applications – from schools to hospitals, office buildings to apartment blocks – make it their preferred choice.
