Panels can be installed in a fraction of the time that poured concrete foundations and traditional exterior walls would take. When panels are delivered to the site, they are often erected in three or four hours. Because the concrete is cured in the factory, foundations can be backfilled as soon as the slab and first-floor are braced. The factory fabrication process reduces or eliminates weather delays.
Insulated precast concrete foundation panels are cast as solid reinforced precast concrete (flat panels), or as reinforced concrete ribbed panels with a thin exterior shell. Some manufacturers cast the concrete against foam insulation as a form, which provides additional insulation (higher R-value) for the structure. Concrete panels can be designed with a strength of 5,000 psi. This results in panels that are stronger than concrete block or most poured concrete walls, but are thinner and lighter weight. Walls may be customized during the order process to allow for door and window openings, steel beam pockets, and brick ledges.
Benefits and Drawbacks of Insulated Precast Concrete Foundation
QUALITY/DURABILITY
Tornado/hurricane damage resistance; fire, termite, and dry-rot cannot interfere with the structure of the modular home with insulated precast foundation.
MARKETABILITY
Insulated precast foundation has low maintenance cost and improved sound-proofing characteristics, making it more marketable. Modular home contractors recommended precast foundation for modular homes because it increases the value of the house.
SCHEDULING
Insulated precast concrete foundation panels cure in the factory, and can be erected in cold temperatures, preventing concrete pour delays.
AFFORDABILITY
Higher up-front cost; requires on-site crane; may require certified installer. Insulated precast concrete foundation systems generally cost between $55 and $65 per linear foot of wall, making them competitive with other foundation walls. Rapid assembly and erection can significantly reduce labor costs. For most projects, a concrete footing is not required, which can reduce on-site material and labor costs. However, panel erection requires a crane which will have added cost, but that cost may be offset by labor and time savings.
An insulated precast concrete system can reduce energy bills throughout its expected life.
Results from the Field of Insulated Precast Concrete Foundation
Field evaluations have demonstrated that insulated precast concrete foundations can be installed quickly and easily, and can offer significant labor savings.
Warranty of Insulated Precast Concrete Foundation
Warranties vary by manufacturer. In Michigan, most manufacturer provide fifteen years warranty, others have longer or shorter time frame for the warranty.
Making the Switch
Precast concrete panels are prefabricated in a factory, and are easier to assemble on site than poured concrete or masonry. Erection time is greatly reduced. Connections, bracing, reinforcement, and openings need to be designed and detailed before fabrication.
