Can precast concrete be used for foundations?
Precast concrete walls and foundations are made in a factory with high-strength, 5,000+ psi concrete. The concrete mix is poured into re-usable molds that are adjusted according to the blueprint specifications.
What foundation that can be precast?
The precast foundation is a reinforced concrete element made up of a tied rebar beam cage incorporated within a semi-precast concrete element which acts as formwork. The element can be used in the construction of column and wall foundation of any type and is suitable for any elevated structure.
Is precast concrete cost effective?
A recent research project directly compared the costs of precast concrete to on-site pouring and found precast concrete slabs save 23 percent over cast-in-place concrete. Columns yielded a similar result, with savings at 21 percent less cost than on-site pouring.
How are precast concrete panels attached to the foundation?
The connections are usually made by placing a loose plate between two structural steel plates that are embedded both in the cast-in-place or the precast concrete panel and welded together. Some connections are designed to bend and yield in one direction while remaining rigid in all other directions.
