Precast Concrete Solid Slabs
Flat precast floor, roof and balcony units for buildings that need a solid concrete section.
Overview
What are precast concrete solid slabs?
A solid slab is a flat precast concrete unit with a full concrete cross-section, reinforced with steel bars, mesh or prestressing strand. It is cast in the plant, cured under controlled conditions and delivered ready to install.
Solid slabs are used where a design calls for a solid section, such as shorter spans, heavy point loads, balconies, landings and areas with many openings or embedded items.
Because the units arrive finished, floors and roofs go in quickly and the building is ready for following trades sooner. Contact your nearest plant for the thicknesses and spans it produces.

Resources
Design data and guides
Technical guides, standard details and plant load tables are in our resource library. The Precast/Prestressed Concrete Institute publishes the industry design standards our plants follow.
For longer spans, see our hollow core slabs and double tees, or explore the other structural products we manufacture.
Process
From design to delivery
Solid slabs start with engineering. Our team works with the design team to confirm spans, loads, openings and connections. The slabs are then cast in the plant, cured under controlled conditions and checked by our quality staff before they ship.
Our plants follow the quality programs of the Precast/Prestressed Concrete Institute, so every piece meets the same dimensions and strength requirements.
Pieces are trucked to site in the order they will be installed. Services such as installation, finishing and detailing vary by plant, so your local Coreslab team will confirm what is available for your project.
Questions
Precast solid slabs: common questions
When should I use a solid slab and not hollow core?
Hollow core is usually more economical for long, repetitive spans. Solid slabs suit shorter spans, balconies, landings, heavy point loads and areas with many openings.
Can solid slabs be used for balconies?
Yes. Balconies are one of the most common uses, because the slab arrives finished and can be installed with the floor system.
How are solid slabs connected?
They bear on precast or other supports and are tied to the structure with connections designed by the engineer for the project.
What sizes do you make?
Sizes vary by plant. Our team can confirm the thicknesses and spans available for your project.
