Standard Precast Walls

 


How much does it cost?
See Specifications page.

How are the panels connected together?
The panels can be joined together with either recessed welded plates or by a bolted connection. These connections are engineered to be strong but hidden—you will never know it is there.

For more detailed information and diagrams of sample connections, please see the Engineering Details Tab.



general information

What are the dimensions of a panel?
An insulated panel is 8" thick. A cross section demonstrates that there is a 4" layer of reinforced concrete, then 2" of rigid closed celled insulation, and finally 2" of lightly reinforced concrete.

There are no set linear or vertical dimensions on our panels as all panels are customized. The maximum length for our panels is 30’ and the maximum height is 13’. Any dimension within this rectangle is easily done.

For the most efficient (ie., most cost effective) dimensions, please see the Specifications page.

Is this like tilt-up or poured in place?
Our walls are prefabricated at one of our plants, and then trucked to the jobsite and installed by one of our experienced crews. "Tilt-up" and poured in place are cast on the jobsite with ready-mix. Because our walls are manufactured offsite and under strict quality control guidelines, we are able to:
1) be more accommodating to the builder, developer and homeowner’s schedule
2) apply more detailed finishes
3) use higher strength concrete mixes with additives like Self Compacting Concrete
4) We can have your building up within a matter of days with little on-site debris
5) Usually the design guidelines, both from structural and aesthetic point of view, are far more flexible using precast

How is this different from concrete block?
Concrete Block, or CMU, are individual blocks that are laid on site. Our walls are prefabricated and brought to the site on trucks. They are erected with cranes, and a typical house can be installed in just one or two days. Our walls are stronger, more energy efficient, and far more resistant to mold, rot, and termites.

What types of exterior finishes are available?
There are a variety of finishes that can be easily applied to our wall. If stucco is the finish you want, we can offer many textures. A variety of brick and stone finishes are also available, and our panels can also accommodate a variety of cladding or siding.

What is the interior finish?
Because we use the add mixture Self Compacting Concrete (SCC), our panels are smooth to the touch with minimal "bug holes" or dimples. It is so smooth that with a light coat of drywall mud you can paint right on top of it for a beautiful plaster-like finish!

How do you hang a picture?
Very easily—a simple drill with a masonry bit will do the trick. There are a variety of different anchor screws that can hold a variety of weights. Patching is easy—just dab some drywall "mud" into the hole and lightly sand over until the finish is smooth. For smaller pictures, adhesive hooks are recommended.

One of the benefits of our walls is that you will no longer have to find a stud to nail into for heavy objects such as mirrors, large framed pictures, shelves, or even cabinets.

How do you treat the joints?
A precast building will have horizontal and vertical joints where the panels come together. We typically treat these joints with a backer rod and caulk on either side. The exterior horizontal joints would lay in-between floors, and the vertical joints are usually located on a corner. The exterior joints can also be grouted over with a small expansion joint applied in order to make them less noticeable. The interior joints are covered by a base board in the case of the horizontal joints or a partition wall on the vertical joints. In cases where a vertical joint is exposed on the interior, it can easily be covered with a tape-less joint compound.

For more information see Specifications page.

How do you treat MEP (Mechanical, Electrical, and Plumbing)?
Electrical and cable raceways can be easily cast into our panels, complete with standard boxes for outlets or switches. The chases are run vertically and swept out through a dropped ceiling or a soffit. Typically electrical panels are located in soft frame partition walls. Electrical and cable lines can also easily be incorporated into to baseboards. For more information see our Engineering Details Tab.

While plumbing lines can easily pass through our panels, we do not run plumbing lines inside them. Plumbing is usually left to a partition wall or our walls can be furred out to accommodate.

HVAC lines and chases typically run through partition walls, the attic, or the crawl space/basement. Chases and lines can be designed into the wall and floor panel layout.

What is your service range?
We have production facilities in Savannah, GA, and Tampa, FL. From these two plants we can service jobs located throughout the Carolinas, Georgia, and Florida (there is roughly a 300-mile freight radius around each plant). We may be able to accommodate larger jobs outside of our range, but only by a few hundred miles.

What is Hollowcore?
Hollowcore is the common term for prestressed concrete floor and roof planks. Hollowcore floors work extremely well with our wall panels, and a design using both allows for incredible design flexibility, speed of construction, and overall strength and quality. Designing with hollowcore in conjunction with our walls allows us to deliver a total structural frame complete with finished exterior walls. Hollowcore comes in planks that are 4’ wide, 6" to 12" inches thick, and can span up to 40’.

How is trim applied?
There are a variety of different details for both interior (baseboard, molding, window surrounds) and exterior (window surrounds, banding, cornices, etc.) details. We can cast in nailers to accommodate trim, or nailers can be applied once the panels are erected. For more information, see the Engineering Details Tab.

How are windows installed?
We can create openings in our panels specific to your window manufacturers request. Several window types can be anchored directly into our panels, or we can cast in nailers to receive them. For more information, see the Engineering Details Tab.

How fast can you erect these panels?
Depending on design, we can usually erect an average of 2,000 to 4,000 SF of building per day.

How long does it take to get panels?
Depending on our backlog, we can usually deliver the building with 90 to 100 days of signing a contract. This allows you time to get your permit, do the site prep, and install your foundation.
