Green roof is a real eyecatcher

This shepherd's hut with a sedum roof attracted a lot of attention at the BALI Landscape Show at Stoneleigh on June 19th and 20th.   The roof was created using Enviromat sedum matting and took less than an hour to install.

First of all, Mark Pawsey, our Green Roof Manager, spread a layer of polyethene over the roof to protect the waterproofing from potential damage from roots and boots.

Next he added a layer of water retention matting...Mark's top tip:  always measure the roof and cut materials to size on the ground...that way you won't accidentally cut through the waterproofing.

Finally, the Eviromat sedum matting was lifted on to the roof and manouvred into position.  It took two people to lift each piece of Enviromat on to the roof, but Mark did all the fitting by himself, before watering the sedum plants thoroughly.

Minutes later, the roof recieved several visitors in the form of hungry bumble bees who found a feast of pollen and nectar from the sedum flowers.
