Waterproofing
Waterproofing can be applied as a coating or a membrane. Waterproofing is not limited to roofs – walls,
parking decks and other structures that need to resist water penetration are all candidates for waterproofing.

Waterproofing Membranes
A green roof is a roof of a building that is partially or completely covered with vegetation and soil,
or a growing medium, planted over a waterproofing membrane. It may also include additional layers such
as a root barrier and drainage and irrigation systems. Green roofs are also referred to as eco-roofs,
vegetated roofs, living roofs, and greenroofs.
In a recent study on the impacts of green infrastructure and in particular green roofs in the Greater
Manchester area, researchers found that adding green roofs will help keep temperatures down, particularly
in urban areas: “adding green roofs to all buildings can have a dramatic effect on maximum surface
temperatures.
Green roofs can be categorized as intensive, "semi-intensive" or extensive, depending on the depth of
planting medium and the amount of maintenance they need. Traditional roof gardens, which require a reasonable
depth of soil to grow large plants or conventional lawns, are considered "intensive" because they are
labor-intensive, requiring irrigation, feeding and other maintenance. Intensive roofs are more park-like
with easy access and may include anything from kitchen herbs to shrubs and small trees. "Extensive" green
roofs, by contrast, are designed to be virtually self-sustaining and should require only a minimum of maintenance,
perhaps a once-yearly weeding or an application of slow-release fertilizer to boost growth. Extensive roofs
are usually only accessed for maintenance.
