Individual flags must be placed onto a **full continuous wet mortar bed**—never utilize spot-bedding or 'dot-and-dab' techniques, as empty cavities beneath natural stone trap pooling water, leading to frost failures and slab cracking under pedestrian or vehicular pressure.\u003c\/p\u003e\n\u003cp\u003eUpkeep remains remarkably low-maintenance because dirt cannot easily embed into the granite core.

Granite is one of the hardest natural paving materials available, making it highly suitable for driveways and areas that support vehicle traffic when installed on a properly prepared, reinforced sub-base.\u003c\/p\u003e\n\u003ch4\u003eDo granite paving slabs become slippery when wet?\u003c\/h4\u003e\n\u003cp\u003eNo. Granite paving typically features a textured or flamed surface finish that provides excellent slip resistance, ensuring safe foot traffic across patios and pathways exposed to heavy rainfall.\u003c\/p\u003e\n\u003ch4\u003eWill the colour of black granite paving fade over time?\u003c\/h4\u003e\n\u003cp\u003eGranite is naturally highly resistant to ultraviolet (UV) light, meaning its deep charcoal tone remains exceptionally stable and won't suffer from significant sun bleaching or fading over years of outdoor exposure.\u003c\/p\u003e\n\u003ch4\u003eIs granite paving suitable for the UK climate?\u003c\/h4\u003e\n\u003cp\u003eYes. Granite performs brilliantly in the UK climate. Because it is frost resistant, highly dense, and low in porosity, it effortlessly withstands repeated harsh freeze-thaw cycles without fracturing.\u003c\/p\u003e\n\u003ch4\u003eDoes granite paving require sealing?\u003c\/h4\u003e\n\u003cp\u003eSealing is optional. Granite is naturally dense and resistant to moisture absorption. However, applying a breathable natural stone sealer can help enhance its deep color profile and offer extra protection against organic stains.\u003c\/p\u003e\n\u003ch4\u003eHow long do granite paving slabs last?\u003c\/h4\u003e\n\u003cp\u003eWhen installed correctly over a structurally stable sub-base, premium granite paving can easily last several decades with minimal maintenance, making it one of the most durable long-term paving investments available.\u003c\/p\u003e\n\u003ch4\u003eCan granite paving be combined with other paving materials?\u003c\/h4\u003e\n\u003cp\u003eYes. Many garden designs combine dark granite with limestone, sandstone, or porcelain paving to create high-contrast decorative borders, pathways, and dynamic zoning features.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Paving and Slabs","offers":[{"title":"Black Granite Paving Slabs Mix Patio Pack 20 mm (68 Pcs\/19.69SQM)","offer_id":48318052630782,"sku":"BG-PAVING-01","price":499.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0752\/3647\/5134\/files\/Black_Granite_Patio_Pack.jpeg_202606041706.jpg?v=1780576367","url":"https:\/\/pavingandslabs.co.uk\/products\/black-granite-paving-mix-patio-pack-20-mm","provider":"Paving and Slabs","version":"1.0","type":"link"}
