Depressed and Yet Happy


Akira Inman is tightening up the brackets that hold the Platon down on the dry stone replica of the Scotish Blackhouse roof built in Grand Valley Ontario during our 2009 DSWAC Rocktoberfest.

This plastic sheeting is a described as a tough waterproof 'double dimpled' high density waterproof membrane that keeps soil away from house foundations. It provides the surface over the planking for us to build the wooden framing on and to then put the soil into so that we can plant the green material, probably chives, thyme and various Sedum. In this case the dimples create some friction for the roots to grab on to, and an air space between the roof and the membrane, to allow air between the damp soil and the wooden sheathing so that the wood doesn't rot.

By the end of last weekend , before I left for Scotland, we had finished applying the layers of membrane and box framing so that we are now ready for adding soil and green roof material. We were 'doubly pleased' to have got it done before the rain moved in.

It's funny about dimples. They are a depression that appears when one smiles. : )
