With its deep slate-blue colour and smooth wirecut finish, it not only offers structural reliability but also adds a distinctive architectural character when left exposed.\n\nThis brick is often used below DPC level, in retaining walls, or anywhere that demands maximum strength and resistance to weathering. Its classic Staffordshire Blue finish also makes it a popular choice for projects where aesthetics and durability need to work hand-in-hand.\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eDimensions (L × W × H):\u003c\/b\u003e215 × 102 × 65 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePack quantity:\u003c\/b\u003e380 bricks per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSize tolerance:\u003c\/b\u003eT2\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRange tolerance:\u003c\/b\u003eR1\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eGross dry density:\u003c\/b\u003e~1650 kg\/m³\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCompressive strength:\u003c\/b\u003e? 75 N\/mm²\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThermal conductivity:\u003c\/b\u003e0.840 W\/(m·K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDurability designation:\u003c\/b\u003eF2\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum water absorption:\u003c\/b\u003e? 7 %\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eReaction to fire:\u003c\/b\u003eClass A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eActive soluble salts:\u003c\/b\u003eS2\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eProduction method \/ configuration:\u003c\/b\u003eExtruded wirecut, vertically perforated\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFinish \/ colour:\u003c\/b\u003eSmooth surface, slate blue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose Staffordshire Slate Blue Smooth Engineering Bricks?\u003c\/h3\u003e\n\nUnmatched strength — With ? 75 N\/mm² compressive strength, these are among the strongest clay bricks available.\n\nLow absorption — ? 7 % water absorption ensures excellent protection against frost, damp, and staining.\n\nDurability — F2 rating means they withstand severe exposure conditions, making them ideal for retaining walls, foundations, and external use.\n\nDistinctive finish — The smooth slate-blue colour gives a timeless appearance when used decoratively.\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003eWhat’s the difference between engineering bricks and facing bricks?\u003c\/h4\u003e Engineering bricks prioritise strength, water resistance, and durability, whereas facing bricks are designed mainly for aesthetics. Engineering bricks like these can be used structurally and in damp or exposed conditions. \u003ch4\u003eCan these be used below the damp proof course (DPC)?\u003c\/h4\u003e Yes. Their low water absorption and high durability make them ideal for use below DPC level or in areas with frequent water exposure. \u003ch4\u003eAre they suitable for decorative use?\u003c\/h4\u003e Absolutely. While designed for engineering performance, the smooth blue finish gives a distinctive appearance, making them suitable for exposed brickwork where aesthetics matter.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/building-supplies\"\u003ebuilding supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/bricks-blocks\"\u003ebricks \u0026amp; blocks\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Ibstock","offers":[{"title":"Default Title","offer_id":51448225300822,"sku":"161863","price":593.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/ibstock-staffordshire-slate-blue-smooth-perf-engineering-brick-pack-of-380-9465472.jpg?v=1772656943","url":"https:\/\/jjbuildingmaterials.co.uk\/products\/ibstock-staffordshire-slate-blue-smooth-perf-engineering-brick-pack-of-380","provider":"JJ Building Materials","version":"1.0","type":"link"}
