As with all concrete products, our paving products may be subject to slight colour variation due to the natural variation in raw materials used and from weathering over time
For a bold, high-impact paving solution, the Kilsaran Newgrange Flag Black Granite 600x400x40mm is a premium choice for patios, paths, and outdoor living spaces. With its larger 600x400mm format and robust 40mm thickness, this flag delivers striking visual appeal with the strength and durability needed for both trade and DIY projects.
The deep black granite finish provides a sleek, modern look that pairs beautifully with light renders, timber features, and stainless steel accents. Its textured surface ensures excellent slip resistance, making it practical as well as stylish.
Key Features:
Black Granite Finish: Deep, contemporary colour with exposed granite aggregate for a premium, textured appearance.
40mm Thick Construction: Built to withstand regular pedestrian traffic and light-use driveways when laid on a proper sub-base.
Large 60 x40 cm Format: Simplifies layout, reduces cutting, and speeds up installation for tradespeople and DIYers alike.
Textured, Slip-Resistant Surface: Provides safe footing even in wet or slippery conditions.
Durable & Low Maintenance: Concrete construction designed to handle Ireland’s variable weather with minimal upkeep.
Lay on a well-compacted sub-base with a full mortar bed for maximum stability — avoid spot bedding. Keep joints even and leave a slight fall away from buildings for drainage. Lock the slabs in place with a quality jointing compound to achieve a neat, professional finish.
