Green Roof Construction

Below we have a blog post from a customer who used Cockle Shells supplied by Mainland Aggregates Ltd as a drainage layer for a Green Roof project. The roof has been taking longer than expected. I was hoping to finish around the 20th July - so running about three weeks behind schedule. Adding the skylight was a late addition to the plan, and other aspects have taken more time because of the size of the roof. At around 55 square metres, it is a giant; you could have a game of tennis up there. On my last blog, I showed pictures of bulk bags of cockle shells and 3 - 8mm leca, and of the shells spread on the roofing membranes as a drainage layer. After completing the shell layer, I put a single line of flint cobbles around the roof deck. They are sitting on a layer of RFG to raise them up to be visible over the retaining boards.
