Product Overview
Smooth red Class B engineering brick, 65mm, supplied in solid form for enhanced strength and resilience in demanding applications.
Designed for high-load applications, it provides compressive strength in excess of 75N/mm² and low water absorption, making it suitable for use in structural walls, retaining walls, and foundations both above and below ground.
At 65mm high, this brick conforms to the UK standard work size (215mm x 102.5mm x 65mm), ensuring full compatibility with common walling and coursing dimensions.
Its size allows straightforward integration with standard mortar joint thicknesses, maintaining bond patterns and structural integrity.
The rich red tone is achieved by firing in an oxygen-rich atmosphere, producing a consistent, uniform finish.
Features & Benefits
- Class B rating (to BS EN 771-1): Assures ≥75 N/mm² compressive strength and ≤7% water absorption for dependable structural performance.
- High compressive strength: Carries significant loads in walls, piers, and foundations without crushing.
- Low water absorption: Resists moisture ingress and freeze-thaw damage for long service in wet or exposed locations.
- Dense, vitrified clay body: Durability in aggressive conditions; good resistance to chemicals and sulfates (check site soils against specification).
- Smooth finish: Neat, uniform appearance where visible; easy to clean down.
- 65mm course height: Integrates with UK coursing for DPCs, retaining walls, and general brickwork.
- Red colour from oxidising firing: Colour results from iron oxidation in an oxygen-rich kiln atmosphere; minor shade variation is normal.
- Solid form: Maximum bearing area and impact resistance; ideal where point loads or high abrasion are expected.
Please Note:
- Colour shade can vary slightly due to raw materials and firing; this is normal for fired clay products.
- Engineering bricks are specified for performance; if appearance is the priority, consider facing bricks.
- Always follow project specifications for mortar selection, DPCs, movement joints, and drainage, especially in sulfate-bearing soils.
Applications
- Foundations & substructures: Robust below-DPC masonry where strength and moisture resistance are required.
- Damp-proof courses: Commonly used in two-course DPCs to interrupt rising damp due to low water absorption.
- Retaining walls, plinths & cappings: Durable in contact with soil or severe weathering exposures.
- Manholes, inspection chambers & civil works: Suitable for drainage structures and utility builds exposed to wet and aggressive conditions.
Installation Guidance
- Lay to good practice: Full mortar beds with solidly filled perpends; maintain tight joints for maximum bearing.
- Detail for moisture control: Incorporate DPCs, weep holes, and drainage as specified; select mortar appropriate to site conditions and any sulfate risk.
- Protect fresh work: Shield from rain, frost, and rapid drying; allow adequate curing before backfilling or loading.
Compliance & Performance
- BS EN 771-1, Class B (≥75 N/mm², ≤7%): Meets requirements for loadbearing masonry in wet/exposed environments.
- Intended service conditions: Suitable for use above or below DPC when designed and detailed to recognised masonry best practice.

How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.
