Built to Belong: Grand Ledge Retaining Wall in Historic Appleby-in-Westmorland, UK

The Challenge: A Tall Wall in a High Profile Setting

At nearly 5 m (16.4 ft) high in places, the retaining wall constructed in Appleby-in-Westmorland, a historic market town in Cumbria, England, was never going to disappear into the background. The village is known for Appleby Castle, an imposing stronghold built in the early 12th century, and its equally historic St Lawrence's Parish Church, with sections dating to 1150. So when Appleby Constructions needed to build a substantial engineered retaining wall in a highly visible location, finding a solution that complemented the market town’s unique character was essential.

The site also introduced practical considerations. Limited access meant deliveries had to be carefully coordinated, while the wall's height and stepped configuration required the installation team to pay close attention to setback, reinforcement, drainage, backfill, and compaction throughout construction.

There was another challenge: this would be installer Appleby Constructions’ first Rosetta Hardscapes project.

The Solution: Two Weeks From Discovery to Delivery

The project’s start can be traced back to an Appleby Constructions team member who came across Rosetta Hardscapes and Manchester, UK-based producer WOTBLOCK on social media. That initial encounter quickly became something more than online browsing.

Just days later, WOTBLOCK managing director Scott Houghton hosted the Appleby Constructions team for a visit to his facility, and they viewed Rosetta’s Grand Ledge wall solution firsthand. The Appleby team knew immediately they’d found the perfect product for a high-profile job in their community. WOTBLOCK had inventory ready to go, the necessary wall design was promptly completed, and block deliveries to the project site began shortly thereafter.

For Appleby’s Ian Boulter Saint, the wait to begin installation was short-lived. “Two weeks, we were getting deliveries, and then Neil was bringing them on the wagon every sort of few days,” he explained. “And we were away with it.”

The Project: A First Install at an Impressive Scale

Installation began with a string line to establish the wall. Because the wall stepped upward through the site, the crew carefully followed the required setback with each step. The Grand Ledge blocks were also intentionally mixed throughout the installation to distribute available textures and avoid repetitive patterns across the wall face. Grand Ledge offers four block sizes and 24 distinctive face textures, making it quite manageable to achieve a finished installation with a natural stone look, even with a project on the scale of the Appleby wall.

For an installation that ultimately stood at almost 5 m (16.4 ft) tall, reinforcement was necessary. The Appleby crew extended geogrid 3.5 m (11.4 ft) into the bank on every other course.

Drainage and backfill were similarly important parts of the wall. Appleby Constructions installed a 6 in (152.4 mm) perforated, pre-wrapped drainage pipe and placed approximately 1.2 m (3.9 ft) of 20 mm (0.79 in) chippings behind the blocks. Excavated material was then returned behind the drainage aggregate and compacted with a trench roller.

For Boulter Saint, working with Rosetta for the first time was an approachable experience. And it didn’t take long for the Appleby Constructions crew to appreciate the simplicity of the installation. “Installing the blocks was brilliant,” he stated.

The Outcome: A Natural Fit for Appleby

For a retaining wall approaching 5 m (16.4 ft) high and occupying such a prominent place in the landscape, Boulton Saint initially wondered how residents would react to such a large installation. The response quickly answered that question.

“Everybody who's come walking past, everybody loves it. And a lot of people think it's either limestone or sandstone… people can't believe it's a concrete product with the mould.” –Ian Boulton Saint, Appleby Constructions

In fact, one of the most striking aspects of the completed project may be how little attention people give to the material from which it’s made. And those who do ask are often surprised to discover that its snapped-stone appearance was created with manufactured concrete blocks. That reaction is particularly significant in a setting where the appearance of a large new retaining structure could easily depart from its historical surroundings.

Just as important, the project gave Appleby Constructions its first experience installing Rosetta Hardscapes. Despite the wall's height, reinforcement requirements, stepped layout, and restricted site access, Boulton Saint came away ready to use the system again.

When asked the ultimate question—whether he would use Rosetta for another project—Boulton Saint didn't hesitate.

“Hundred percent. If we get another one like this, we'll be putting it in.”
