Hollowcore floor
Offsite residential construction, Glossary of terms, published by Buildoffsite in 2018, defines hollowcore floor as: ‘Prestressed, pre-cast concrete slab units that derive their name from the voids or cores which run through the units. The cores can function as service ducts and significantly reduce the selfweight of the slabs, maximising structural efficiency. Units are generally available in standard 1200 mm widths and in depths from 110 mm to 400 mm.’
