Avoid using loose sand beds or spot-bedding methods for vehicle paths, as trapped water can shift individual setts during winter freeze-thaw cycles. Point the boundaries using an exterior-grade natural stone jointing compound or resin mortar to actively prevent weed growth.\u003c\/p\u003e\n\n\u003cp\u003eOngoing maintenance is minimal due to the high density and low porosity of natural granite stone. Periodically brush away loose garden debris and clean the area with an annual pressure wash to keep moss and algae at bay. Applying an impregnating stone sealer after installation is highly recommended to protect the stone against oil drips and enhance the depth of its black colorway.

This causes the surface granules to burst, leaving a beautifully textured, high-friction face that provides outstanding slip resistance during wet and icy UK winter weather.\u003c\/p\u003e\n    \n    \u003ch4\u003eAre black granite cobbles suitable for driveways?\u003c\/h4\u003e\n    \u003cp\u003eYes. Granite is an exceptionally hard and dense natural stone. When laid over a compacted MOT Type 1 aggregate base and fixed into a full, continuous wet mortar bed, these 2CM calibrated cobbles provide a durable, load-bearing surface for domestic vehicular driveways and edging borders.\u003c\/p\u003e\n\n    \u003ch4\u003eHow many square metres does one pallet cover?\u003c\/h4\u003e\n    \u003cp\u003eOne pallet of Black Granite Cobbles 100x100 2CM covers approximately 10 to 12 square metres when laid with standard 10mm joints. We recommend adding a 10% wastage allowance to your measured area, particularly for projects with curved edges or angled cuts.\u003c\/p\u003e\n\n    \u003ch4\u003eDo black granite cobbles need to be sealed?\u003c\/h4\u003e\n    \u003cp\u003eSealing is recommended but not mandatory. A natural stone impregnating sealer will enhance the depth of black colour and protect against staining from oil, moss and garden use. Unlike porcelain paving which never requires sealing, natural granite benefits from sealing in high-use or exposed outdoor areas.\u003c\/p\u003e\n\n    \u003ch4\u003eWhat is the difference between machine cut and hand-split cobbles?\u003c\/h4\u003e\n    \u003cp\u003eMachine-cut cobbles feature precise, dimensionally uniform edges that ensure rapid installation, flat bedding, and perfectly straight joint lines. Hand-split or riven cobbles offer a highly irregular, rustic finish. These granite cobbles are machine-cut for clean, contemporary architectural lines.\u003c\/p\u003e\n\n    \u003ch4\u003eDo you deliver to Bicester and Oxfordshire?\u003c\/h4\u003e\n    \u003cp\u003eYes.
