Marshalls is a leading UK manufacturer of sustainable solutions for the built environment, offering a comprehensive range of products across landscaping, building, and roofing sectors. With a heritage dating back to the 1890s, Marshalls has built a reputation for quality, innovation, and a commitment to creating better places. Their landscaping division provides an extensive selection of paving, kerbs, walling, and street furniture, catering to both commercial and domestic markets. In the building sector, Marshalls supplies essential materials such as concrete bricks, masonry, drainage solutions, and aggregates, all designed to meet the highest standards of performance and sustainability.
In recent years, Marshalls has expanded its roofing portfolio through the acquisition of Marley, a renowned manufacturer of pitched roofing systems. This strategic move has enhanced their offerings to include concrete and clay tiles, timber battens, and innovative roof-integrated solar panels, aligning with the growing demand for energy-efficient building solutions. Marshalls’ dedication to responsible sourcing and environmental stewardship ensures that their products not only meet aesthetic and functional requirements but also contribute to a more sustainable built environment.
For the appearance of natural stone walling at an affordable price, Cromwell Stone Walling from Marshalls is an ideal choice. A reconstructed walling stone, it uses Yorkstone aggregates quarried from the same natural sources as those used for natural stone walling to closely replicate the visual and textured characteristics of natural stone.
Suitable for load-bearing and non-load-bearing use, the hydraulic press manufacturing process results in low water absorption, ensuring the high-quality appearance is maintained over a long-term period.
The pressing process also delivers dimensional accuracy for time savings on site, while still achieving the visual impact of random and variably sized natural stone walling.
