I had a dead looking corner and wanted to screen off the lower railtrack , so I had a few blocks and slabs and a few left over tins of expanding foam and decided to experiment,
halfway through I was planning to move house again,so the project sat for a few months unfinished
After finding out that the move was off I started agin last month and finished it and started landscaping
the foam has worked well so far and a polysheet over the top has kept everything dry,
the finished tunnel was covered with slate scree from a work colleague, when it stops raining I will tidy up the edges and build a tunnel portal to complete
