The green city

The countryside is moving into the city. A slight exaggeration maybe, but it is a fact that green walls and roofs are becoming increasingly common in the urban environment.

A roof covering of moss, sedum, herbs or grass not only makes a colourful addition to the concrete jungle, it also has a positive environmental impact.

As well as the plants absorbing rainwater that evaporates back into the atmosphere, green roofs also dampen the sound level, save energy, reduce the temperature and have air purifying properties. It is a fact that a 10 m2 roof surface of dry vegetation absorbs as much carbon dioxide as a tree.

And let’s not forget biodiversity. Green roofs attract bumblebees, butterflies and other valuable insects, not least bees that play a crucial role as pollinators for agriculture, gardens and flower meadows. Bituminous membranes are used in order to protect the construction from water and roots growing through the material.

Sustainable Development driving innovation

It is important to have both incentives and clear requirements to drive developments forwards and to make sure that the industry is making a positive contribution to sustainable development.

In good shape

Most local authorities in the UK think of cold mix asphalt as a new and relatively untested road construction material. But it has been used successfully in the UK for more than 10 years, including a section of trunk road in Scotland built with a cold mix asphalt base course in 2008.

Safety

Knowledge key to safe deliveries

Bitumen is delivered hot and therefore precise procedures are needed in order to minimise safety risks such as burn injuries. Safety is something on which the transport company Kördel maintains a constant focus.
