Green Roof

Asphaltech mastic asphalt is an ideal waterproofing material for extensive green roofs, intensive roof gardens and biodiversity roofs. These finished can enhance environments, control water run-off, and reduce noise transmission.

Extensive green roofs require little long term maintenance. It is completely resistant to root penetration and does not require an additional anti-root barrier.

For the environmentally conscious it is an ideal waterproofing material for extensive green roofs, intensive roof gardens and biodiversity roofs.
It is completely resistant to root penetration and any water collected of the Mastic surfaces is potable.

Used in this manner it has also been found to increase the thermal characteristics of the roof, reduce noise transmission and increase the life expectancy of waterproofing membrane.

By selecting our Green Roof system, you have selected one of the greenest construction materials available with zero carbon emissions.

The Polymer Modified Mastic Asphalt roofing industry was the first in the world to achieve a carbon zero status. It was able to achieve this through key initiatives such as 100% recyclable, lowering the heating requirement for the melt and 50+ year durability.
