Celcon High Strength Foundation Block 300mm 7.3N/mm2
Available in Standard Grade (3.6N/mm²) and High Strength Grade (7.3N/mm²), Foundation Blocks can be used to support 3 storey constructions. They are suitable for the support of solid or cavity walls, framed construction or suspended floors, including beam and block.
They offer the following benefits in use:
Enhanced thermal performance:
their use reduces heat loss from ground floors
they have exceptionally good resistance to freeze/thaw conditions
they weigh one third of an equivalent dense aggregate block
an independent report by Davis Langdon LLP concludes Celcon Foundation Blocks are up to 24% cheaper than dense aggregate block
Speed of construction:
Celcon Foundation Blocks enable a quick and reliable construction as only one wall has to be set out and there is no need for wall ties or lean mix fill.
H+H's Celcon Blocks High Strength Grade (7.3N/mm2) and Super Strength Grade (8.7N/mm2) are used principally where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings.
Our higher strength grade blocks were re-named from Hi-Seven to High Strength and Hi-Ten to Super Strength in 2011. Apart from the name, there has been no technical specification changes to the product and it can be used in exactly the same way and in the same applications as before*.
