The structural integrity of the Insulbrick ICF building system is formed entirely by its concrete core. We recommend the use of 32mpa concrete with aggregate no greater than 7mm. The slump required depends on the project, the stage of the project and which insulbrick you are using. Concrete can be hand-mixed on site or delivered by your local concrete supplier.
If the insulbricks are properly braced you can pour up to three metres at a time.
