GAME OF THRONES LOCATION OPTS FOR WEBWALL RETAINING WALL SYSTEM

Doune Castle is a medieval stronghold near Stirling in central Scotland , originally dating back to the thirteenth century . The castle was used as the main filming location for the Winterfell Kingdom in the Game of Thrones TV series and as a backdrop for various scenes in the Monty Python and the Holy Grail film .
As part of a maintenance programme to upgrade access routes to and around the castle , a new stepped ramp and wider section of road from the main entrance was designed . The change in elevation from the road to the top of the footpath required a new retaining structure to secure the cut slope .
ABG ’ s vegetated Webwall system was chosen as a faster construction that minimises the number of carbon intensive deliveries associated with using hard landscaping materials . The flexible HPDE geocellular panels are a natural green colour at the front cells of the panels to blend in with the woodland setting and they are easy to unfold , expand and pin into position to suit the curved footprint of the site . The first layer of panels are stretched out and pinned into position into an excavated footing before backfilling with site won fill . The fill is compacted in tiers and the process is repeated until the full height of the wall has been constructed . The easy to handle and flexible nature of the Webwall panels enables a fast installation , completed in just 4 days compared to the additional time and cost ( from both a financial and carbon point of view ) associated with building an equivalent stone structure .
