Its soft texture and subtle variation give it a traditional look, making it well suited to heritage and restoration projects. As with all clay bricks, natural shade differences are expected, so blending from at least three packs during installation is recommended to achieve a consistent finish.\n\nThis brick provides heritage character with dependable performance, offering frost resistance, moderate strength, and higher absorption levels typical of waterstruck stock bricks when detailed correctly.\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\nSize: 215mm × 102.5mm × 65mm\nColour: Red \/ Multi\nTexture: Waterstruck Stock\nWater Absorption: ≤ 21%\nDurability: F2\nCompressive Strength: ≥ 21 N\/mm²\nPack Quantity: 430\nGross Dry Density: 1640 kg\/m³\nSize Tolerance: T1\nRange Tolerance: R1\nActive Soluble Salts: S2\nReaction to Fire: Class A1\n\n\u003ch3\u003eDescription \u0026amp; Usage Notes\u003c\/h3\u003e The Oast Russet Sovereign is produced using the waterstruck process, which creates a lightly textured surface and natural tonal variation. Its russet and multi colouring gives depth and warmth, fitting both restoration and character builds.\n\nWith water absorption ≤ 21% and compressive strength ≥ 21 N\/mm², this brick is best used for facing applications rather than heavy structural work. Its F2 frost resistance ensures durability in normal UK exposure conditions. Proper construction detailing — including cavity design, flashing, drainage, and compatible mortar — is essential for long-term performance.\n\nAlways blend bricks from multiple packs to minimise colour banding, and consider building a sample panel to confirm tone and finish before committing to a large order.\n\n\u003ch3\u003eFAQs\u003c\/h3\u003e \u003ch4\u003eIs ≤ 21% water absorption suitable for external walls?\u003c\/h4\u003e Yes — this is normal for waterstruck stock bricks and performs well with correct construction detailing. \u003ch4\u003eWhat does the F2 durability rating mean?\u003c\/h4\u003e It means the brick is frost-resistant and suitable for normal UK external exposure conditions. \u003ch4\u003eWill the russet multi tones vary between packs?\u003c\/h4\u003e Yes — shade variation is natural with clay bricks. Mixing from at least three packs during laying helps achieve a consistent finish.","brand":"JJ Building Materials","offers":[{"title":"Default Title","offer_id":54801332502870,"sku":"162007","price":564.44,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/jjbuildingmaterials.co.uk\/products\/wienerberger-hartlebury-oast-russet-sovereign-facing-brick-pack-of-430","provider":"JJ Building Materials","version":"1.0","type":"link"}
