Foundation Blocks

Learn more about foundation blocks

Foundation blocks are used for below-ground and loadbearing masonry work where the build needs a strong, stable base. They are commonly specified for foundation walls on new builds, extensions and structural projects, helping transfer loads safely through the construction.

Within our range, you can find foundation blocks suited to different project requirements, depending on the wall design, section size and site specification. They are typically used as part of a wider masonry package, alongside compatible blocks, mortar and site equipment. Always check the product specification and structural requirements before ordering for the job.

Typical uses

• Building foundation walls for residential, commercial and extension projects. 

• Supporting below-ground loadbearing masonry where specified by the design. 

• Bringing masonry work up from groundworks into the main wall construction. 

• Working alongside wider bricks and blocks packages on site. 

How to choose the right foundation blocks

• Match the block size to the structural drawings and wall build-up. 

• Check loadbearing requirements against the product specification. 

• Confirm suitability for below-ground use and the intended application. 

• Review dimensions carefully so they work with your layout and cut list. 

• Check compatibility with mortar, fixings and surrounding masonry materials. 

• Follow project guidance from the specifier, engineer or building control where applicable. 

Before you order

• Measure the foundation wall areas accurately before calculating quantities. 

• Allow for cuts, breakages and sensible wastage based on the layout. 

• Check site access, storage space and handling requirements before delivery. 

• Confirm the mortar and installation materials needed for the job. 

• Review fulfilment options such as delivery or Click & Collect.
