Concrete Padstone 215mm x 140mm x 102mm – PAD01
The Concrete Padstone 215mm x 140mm x 102mm, also known as PAD01, is a compact, high-strength precast concrete unit designed to provide a stable bearing beneath structural beams and lintels. It helps spread concentrated structural loads through the supporting brickwork or blockwork, reducing excessive pressure on a small area of masonry.
Steel beams and structural lintels may carry significant loads from floors, roofs, walls and other parts of a building. These forces are transferred through the ends of the structural element into the wall below. Ordinary bricks or standard building blocks may not always provide a suitable bearing for this concentrated load.
A correctly specified padstone creates a stronger intermediate bearing between the beam and the supporting masonry. It distributes the load across a greater area and helps transfer it more effectively into the surrounding structure.
PAD01 measures 215mm long, 140mm wide and 102mm high. It is one of the more compact standard padstone sizes and is suitable for structural details where this specific bearing area has been calculated and approved.
What is a concrete padstone used for?
Concrete padstones are installed within masonry to provide a strong and level base for structural components. PAD01 may be used in a range of applications, including:
- Supporting structural steel beams
- Providing bearings beneath concrete lintels
- Supporting steel lintels where specified
- Creating structural openings in masonry walls
- Load-bearing wall alterations
- Residential extensions
- Property renovations and refurbishments
- New-build construction
- Supporting suitable structural elements
- Creating compact bearing points within brickwork or blockwork
A padstone is a structural building component rather than a standard concrete block. Its size, position and installation should always follow the approved structural design.
PAD01 dimensions
The nominal product dimensions are:
- Length: 215mm
- Width: 140mm
- Height: 102mm
- Product reference: PAD01
- Approximate imperial size: 9″ x 5½” x 4″
- Material: High-strength precast concrete
The compact 215mm length makes PAD01 suitable for details where space is limited and a smaller bearing area has been specified. Its 140mm width can be incorporated into compatible masonry construction, while the 102mm height provides a relatively low-profile structural bearing.
The dimensions alone do not determine whether PAD01 is suitable for a project. The required padstone must be established through structural calculations that consider the beam reaction, available end bearing, wall construction and masonry strength.
High-strength precast construction
PAD01 is manufactured from dense, high-strength precast concrete. This provides a stronger bearing surface than an ordinary brick or conventional masonry block and helps the unit withstand concentrated structural loading.
Precast manufacture takes place under controlled factory conditions, helping provide consistent dimensions and material performance. The finished padstone arrives ready to be installed, avoiding the need to prepare formwork and cast an individual concrete bearing on site.
Practical benefits include:
- High-strength concrete construction
- Consistent factory manufacture
- No on-site concrete casting required
- No separate shuttering or formwork needed
- Reduced preparation and curing delays
- Ready to incorporate into suitable masonry
- Defined dimensions for easier specification
- Suitable for permanent structural applications
Although the padstone is supplied as a cured precast unit, the bedding mortar and surrounding masonry must still achieve adequate strength before the full structural load is applied.
Selecting the correct padstone
The correct padstone size depends on several project-specific factors. These include the load carried by the beam, the reaction at its bearing point, the required bearing area and the strength of the supporting brickwork or blockwork.
PAD01 should only be used where a 215mm x 140mm x 102mm padstone has been specified or approved by a qualified structural engineer or another suitably competent professional.
Do not select this product solely because its dimensions fit the available opening. A padstone that physically fits may not provide the bearing area or load distribution required by the structural calculations.
PAD01 should not be substituted for another padstone size without professional approval. Always consult the structural drawings and calculations before ordering or beginning installation.
Installation guidance
The supporting masonry must be sound, stable and capable of accepting the transferred structural load. Install the padstone on a complete, even bed of suitable mortar so that its entire underside is properly supported.
Position the unit level and in the orientation shown on the structural drawings. The beam or lintel must sit correctly on the padstone and achieve the specified end-bearing distance.
Inspect the padstone before installation. Minor cosmetic marks are common on concrete products, but a unit with severe cracks or structural damage should not be used without professional assessment.
Do not cut, drill or otherwise alter the padstone unless the modification has been expressly approved by the structural engineer. Allow the bedding mortar and supporting masonry to develop sufficient strength before applying the full load.
Colour, finish and size variations
Precast concrete is manufactured from cement, water and naturally sourced aggregates. Variations in these raw materials, production batches and curing conditions can affect the final appearance.
Please note: Colours and sizes may vary slightly due to the manufacturing process. Product images are provided as a representative guide, and the unit supplied may differ slightly in appearance.
Minor shade variations, surface marks, small air pockets and slight edge irregularities are normal characteristics of precast concrete. These cosmetic variations do not necessarily indicate a fault, provided the product remains structurally sound and is within the manufacturer’s permitted tolerances.
Padstones are functional structural components rather than decorative products. Exact colour, texture and finish matching between individual units cannot therefore be guaranteed.
