Dry Stone Walling at Roseberry Topping.

Back in December 2013 we spent a weekend on Roseberry Common with a group of our regular volunteers rebuilding a section of dry stone wall. It was a big job as most of the volunteers had not done any walling before and were learning as they went. So we returned on 12th January 2014 to finish the job. The wall was in a bad state of repair so we took the opportunity to rebuild it from scratch. This meant taking down the old wall and digging out a shallow trench, into which we position very large foundation stones which form a stable platform for the wall to sit on for many years to come.

For a strong and stable structure, the wall will ideally be half as wide at the top as it is at the bottom. The wall gets built in courses (or layers), using a batter frame and string lines as a guide. When one course is complete you move the lines up and continue on the next layer.  The largest stones are used at the base of the wall, gradually working up to using the smallest at the top. Our wall was a double skin wall, with ‘hearting’ stones filling the gaps in the middle. We also use ‘through’ stones at regular intervals which span the full width and tie in both sides of the wall. For a bit more information about walling see Chris’s post from back in 2012: https://dayinthelifeofaranger.wordpress.com/2012/03/06/dry-stone-walling-2/ Here’s some pictures of the volunteers who took part with their finished section of wall…
