Celcon Blocks: High Strength Grade  


H+H's Celcon Blocks High Strength Grade (7.3N/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.

All Celcon Blocks are BBA certified, are fire resistant (100mm walls, up to 4 hours, 2 hours if loadbearing dependant upon the Grade) and have been classified 0 surface spread of flame and non-combustible to Class A1 (the highest class). Celcon Blocks are available in thicknesses from 75mm to 215mm.
