DeVicci Blocks

HD Uses & Applications
HD Blocks are Dual Chamber Insulated “Heavy Duty” Structural Blocks for Real Life Building Structures. Practical for Residential, Commercial & Industrial applications.

Although both NS & HD versions have different uses and applications, they both build using the same technique, which is to erect 2 rows at a time, more sophisticated “Real Life” builds requires professional skills.

Aesthetically one can apply any desired finish on both the Inside & Outside of the walls.

Advantages of “HD DeVicci Blocks”
Minimal Tape Measuring. Using your tape to measure pieces is one of the biggest time wasters on a job site. Our fixed dimension blocks and starter tracks make it easy to do a visual calculation. If you can multiply by 2 you’re all set.
Constructing with NS blocks is very similar to building with HD blocks for Real Life Size buildings (with the help of specialized technicians.) HD blocks are insulated and ready for concrete filling which makes the structure ultra-durable with among very highest R-Value.

The miniatures also allow Professionals and Auto-Builders to create mini scale designs for an eventual Full Scale HD build. Allows you to do a manual block count, fill the “Inventory file” (xls template) *insert jpg model in the xls file

HD Blocks Applications
Real Life Building Construction for Residential, Commercial & Industrial applications. The insulated, concrete filled, sealed perimeter envelope of such a building, guarantees;
– High energy efficiency, help consume less energy
– Antibacterial, Mold prevention
– Block infiltration of rodents, insects, pests & parasites.
– Easily washable exterior and interior in case of water damage or sewage overflow disaster.
– Materials used are Long life & durable
– Fire retardant
The HD Blocks need to provide box cutouts for cable passages for electrical outlets and light switches. These cutouts are typically located at the 1st row of assembly and the top of 3rd row / bottom of 4th(at @ 48”) for light switches / interrupters or counter top electrical outlets & switches.

We’ve developed a starter track to sketch the shape of the building on the footing to have the precise loop dimension and to insert vertical rebar at precise locations (every 2 feet).

Once our starter track is placed and the building is sketched, start placing the blocks on the starter track. Note; 1st row must have Blank spaces for doors while rows 2 to 6 can & will have Window openings. It is important that you build the first 2 rows to make sure that you have all window & doors openings and box cutouts located properly as designed on your plan or else you’ll be in for unpleasant surprises.

Once those 2 first rows are verified OK and you’ve closed the perimeter “Loop” you may then continue building by copying the rows of blocks from row 1 to row 3 & row 2 to row 4, (odds & evens) while paying attention to window & door opening heights.

Special attention needs to be directed at the top of all openings, usually rows 5, 6 or 7 (depending on ceiling height, 6 rows = 8 feet) that’s where the blocks have to “Lock in” correctly. The starter track for the entrance doors & garage door openings are laid on the ground as well to make extra sure that the top of the openings distance would match the distance laid on the ground, or else there’s no way that they could lock at the top.
Remember, the DeVicci Blocks have fixed dimension, like “Legos”, you cannot cut them to make them “fit”, as with the ICF Styrofoam Panels, all dimensions must be perfect from the ground up, this will result in a very straight / square structure, HD cavities are then ready to be filled with concrete and gelled in place forever that create a Dual Chamber of Insulation around your concrete structure.

Note: Cut out door heads to meet building code requirements. You may have to cut out a few inches at the top of the entrance door head (bottom of row 6) to fit the door frame. Blocks are 16” high x 5 rows = 80 inches. In most cases the minimum door opening can be 84 inches, therefore you’ll need to cut 4 inches at the top of your door entrances.

Note: if you plan on using arched doors then cutting the door head will not be necessary.

For multi story buildings, “Joist Blocks” are installed at Row 7 or 8 (depending on ceiling height). The 16” block height allows for plenty of margin to meet the minimum 8’ ceiling requirements. Several Joist Blocks can accept many types of joists and concrete floor thickness. You may want to have a 2 inch cement floor while others may prefer 4 inches of structural cement floors. Adding rubber mats underneath cement floors increases acoustic dampening properties.
