Concrete Slip Brick 40mm (215x100x40mm)
£0.77 £0.92 incl. VAT
Concrete slip bricks (40mm) are used to maintain coursing in blockwork, particularly in block and beam flooring systems where full bricks won’t fit. These high-strength dense concrete slips provide a reliable, cost-effective alternative to cutting full bricks on site.
Concrete Slip Brick 40mm
Concrete slip bricks (215 × 100 × 40 mm) are slim precast bricks made from dense aggregate, offering a compressive strength of 20 N/mm² for reliable performance. Designed to maintain accurate coursing heights where full-depth blocks or bricks won’t fit, they are commonly used in block and beam floor systems or to adjust masonry without the need for cutting full-size bricks.
Key Features & Benefits:
- Cost-Effective and Reliable: A traditional dense aggregate solution that delivers strength and durability without unnecessary cost.
- Versatile Applications: Suitable for use both above and below DPC level, ideal for infill, wall construction, and coursing adjustments.
- High Density and Strength: Manufactured from high-density concrete for dependable performance in demanding environments.
- Compatible with Dense Aggregate Blocks: Works seamlessly alongside dense aggregate blocks, ensuring consistency in masonry construction.
- Ideal for Cladding or Rendering: Provides a solid base where walls will be finished with render or cladding systems.
- Meets Industry Standards: Manufactured in accordance with BS EN 771-3:2011 for masonry units.
Technical Specifications:
- Dimensions: 215mm (Length) x 102.5mm (Width) x 40mm (Height)
- Weather Resistance: Resistant to rain, frost, and thawing, with excellent freeze-thaw performance
- Strength: 20 N/mm²
- Compliance: BS EN 771-3:2011
Common Uses of 40mm Concrete Slip Bricks
- Adjusting coursing heights in blockwork
- Infill between beam and block flooring systems
- Packing under lintels and structural openings
- Levelling courses where full bricks are impractical
- General masonry adjustments without cutting bricks

What are concrete slip bricks used for?
Concrete slip bricks are primarily used to adjust coursing heights in masonry where full-sized bricks or blocks are too large. They are commonly installed in blockwork, beam and block flooring systems, and around structural openings to maintain level courses without the need for cutting.
Can concrete slip bricks be used below DPC level?
Yes, concrete slip bricks can be used both above and below damp proof course (DPC) level. Their dense aggregate composition provides good resistance to moisture, frost, and ground conditions, making them suitable for a wide range of structural and below-ground applications.
Are slip bricks structural?
Concrete slip bricks offer high compressive strength (typically around 20N/mm²), but they are not generally used as primary structural load-bearing elements. Instead, they are designed for levelling, packing, and maintaining coursing within structural masonry systems.
Do I need to cut slip bricks on site?
No, slip bricks are manufactured at a reduced height (typically 40mm), specifically to eliminate the need for cutting full-sized bricks. This saves time on site and ensures a consistent, accurate finish in masonry work.
What is the difference between slip bricks and standard bricks?
The main difference is size and purpose. Slip bricks are thinner (usually 40mm high) and are used for adjusting course heights, while standard bricks are typically 65mm high and used for full masonry construction. Slip bricks help avoid cutting standard bricks to fit awkward gaps.
