What Are Concrete Padstones?
Concrete padstones are high-strength dense concrete blocks used to distribute concentrated structural loads within masonry construction. They are commonly installed beneath steel beams and some concrete lintels to help spread loads more evenly into the supporting wall.
By increasing the bearing area beneath structural openings, padstones help reduce excessive point loading on brickwork and blockwork. They are widely used in residential, commercial, and extension projects where structural loads need transferring safely into masonry supports.
Structural Specification
Padstone size, strength, and specification should always be determined by a suitably qualified structural engineer or in accordance with approved project drawings and Building Control requirements.
High Strength Concrete Padstones
Most modern concrete padstones are manufactured using high-density concrete designed for structural load distribution applications. Our range of Naylor C50 concrete padstones includes multiple sizes and configurations, including standard rectangular, extended reinforced (ER), and L-shaped variants.
Concrete padstones are commonly specified beneath structural steel beams, RSJs, and wider span lintels where concentrated structural loads need distributing more effectively into the supporting masonry.
Common Concrete Padstone Sizes
Concrete padstones are manufactured in a wide range of dimensions depending on the structural requirements of the project. Common sizes typically range from 215mm up to 900mm in length, with multiple widths and depths available depending on the application and specification.

Dimensions shown represent common concrete padstone sizes manufactured by Naylor. Specification should always be confirmed by a suitably qualified structural engineer or project designer.
Extended Reinforced (ER) Padstones
Our range also includes extended reinforced (ER) concrete padstones designed for applications requiring increased bearing area and load distribution beneath structural openings and steelwork.
- ER1: 600 x 100 x 65mm / 900 x 100 x 65mm
- ER2: 600 x 100 x 140mm / 900 x 100 x 140mm
- ER3: 600 x 140 x 65mm / 900 x 140 x 65mm
- ER7: 600 x 100 x 215mm / 900 x 100 x 215mm
Padstones for Steel Beams and Lintels
Padstones are frequently used beneath structural steel beams and wider span cavity wall lintels where loads need transferring more effectively into the supporting wall construction.
Alongside standard rectangular units, our range also includes extended reinforced (ER) and L-shaped concrete padstones for a variety of structural support applications.
