What is Hollowcore?
Hollowcore is the common term for prestressed concrete floor and roof planks. Hollowcore floors work extremely well with our wall panels, and a design using both allows for incredible design flexibility, speed of construction, and overall strength and quality. Designing with hollowcore in conjunction with our walls allows us to deliver a total structural frame complete with finished exterior walls. Hollowcore comes in planks that are 4 wide, 6″ to 12″ inches thick, and can span up to 40 .
