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, modern paving statement, the Kilsaran Massimo Flag Black Granite is the ultimate choice for patios, pathways, and large outdoor areas. Its oversized 80 x 40cm format and 40mm thickness provide a premium, contemporary look with the strength and durability required for trade installations and serious DIY projects.
The deep Black Granite finish offers a striking, architectural aesthetic, perfectly complementing light render, timber, and metal features. With a textured surface for slip resistance and a robust concrete build, this flag combines style with long-term performance.
Key Features:
Black Granite Finish: Rich, deep colour with exposed granite aggregate for a high-end, textured appearance.
40mm Thick Construction: Engineered to handle patios, paths, and light-use driveways when installed on a proper sub-base.
Large 80 x 40cm Format: Dramatic scale reduces the number of joints, speeds up installation, and creates a premium, contemporary layout.
Textured, Slip-Resistant Surface: Provides safe footing in wet or slippery conditions.
Durable & Low Maintenance: Concrete construction designed to withstand Ireland’s climate with minimal upkeep.

TJ’s Tip:
For a lasting finish, lay on a well-compacted sub-base with a full mortar bed — avoid spot bedding. Keep joint widths consistent and allow a slight fall for drainage. Use a quality jointing compound to lock the slabs in place and achieve a clean, professional look.
