Technical Data

What is Hollowcore concrete?

Most often used in the construction of flooring, hollow core concrete planks are pre-stressed, precast concrete elements that are structurally efficient and light weight. Hollow core precast concrete has continuous voids that run longitudinally throughout the planks. Also known as voided slabs, precast slabs, hollow core planks or concrete planks, hollow core concrete is a cost effective material which is a popular choice when constructing multi-storey buildings.

Hollowcore planks, due to the manufacturing method and structurally efficient cross section, use significantly less material than a solid equivalent (~30-50% less concrete). This combined with the reduced cement in the zero slump concrete used for the hollowcore production (~25-30% cement reduction) results in a total of 40-60% less cement required.
