Frequently Asked Questions

Yes, it will. Tests have been conducted to prove the strength of our product. Upon completion of the final testing by an independent testing lab, we will submit our test results and design criteria to the International Code Council (ICC) Evaluation Service for approval.
In the same manner insurers cover wood frame construction (among other conventional forms of construction), there should be no hindrance in the market from utilizing Lok-N-Blok, especially once the ICC certifies the product for use.
We have a social presence on Twitter, Facebook, Instagram, and LinkedIn and maintain our own website at Through these channels, you can watch and follow what is taking place in the company and reach out to us for more detailed information.
Principally, the only tool necessary for building the wall is a rubber mallet or hammer. No nails, glue, or mortar are needed to connect our blocks. The walls lock in place using the integral dovetails and posts/receivers.
The general-purpose structural block is charcoal gray in color. Due to our desire to make the block UV resistant, we have added carbon black to our material, which creates the dark color of the block. We are rapidly working to find an additive that is economically feasible in providing UV resistance while allowing us to produce products in any custom color you could imagine. If you are building a structure that will be entirely clad, and you don’t require UV resistance, custom colors would be immediately available.
Lok-N-Blok is designed to be cut into segments of three inches. The blocks have cut lines designed into them and allow full interconnectivity when the cut is made. Features built into the design will leave you with a female dovetail connection when the block is cut along those lines.
At present, we are using a V2 rated composite material, which means that the burning stops within 60 seconds after the ignition source is removed. Lok-N-Blok recognizes the need for a flame retardant block and is working to provide that in the future.
Although Lok-N-Blok was designed for use as a structural building product mainly for use in exterior walls, there is nothing prohibiting its use for interior walls. The cost of the structural building block might prohibit this somewhat, but as a company, we know the desire to use our complete system, and we are developing a lighter weight, non-load bearing block that will be easily used for all interior walls.
Standard roof truss will set atop the wall and can be tied to the top plate that is secured to the blocks by the post tensioning system. In the same manner you would attach your roof system with conventional construction methods, you would attach to Lok-N-Blok. Our design is so simple, it doesn’t require any new methods or tools to construct your project.
The same as with any other conventional materials or conventional form of construction through the simple use of nails, screws, or glues. Lok-N-Blok has a higher holding strength than pine lumber.
The final connection is made using a post tensioning system that runs from the footers or slab vertically through the entire wall to the top plate. This holds the wall to the footer, but it also compresses the entire walls to ensure all interlocks are pulled tightly together.
The blocks are designed to simply interlock together at the corners using the dovetails that are produced in the block. You can use those dovetails along each side of the block to make corners and as well as provide a secure means of interlocking perpendicular walls—no special blocks needed!
It is difficult to answer that question on a block-by-block basis to make a comparison to other materials. One must consider the total installed overall cost of a constructed wall. Side-by-side comparisons of construction time needed show a 50% savings in time over wood framing and an 80% time savings over concrete block walls. Given our wall merely stacks and interlocks together, a wall built with Lok-N-Blok is ready for interior and exterior cladding the minute you are finished. No additional insulation work, house wrap, or sealing are required. A completed wall ready for finish goods would be competitive in cost to wood framing, making it a very affordable alternative building material.
The middle of the block has integral cavities/channels nearly 1½ inches in diameter running both horizontally and vertically through the body. Greenfield or Romex could be run through this cavity and brought out at any point by simply drilling through the side of the block for access.
with a solid wall surface, it is easier for many applications (such as cabinetry) when holding to a solid wall is required.
You would use the same method used for other forms of construction. You simply leave the rough opening in your block needed to insert the door or window and facially attach the unit using the nailing flange.
No, we have not constructed anything yet that would be required to have building code approval. We have, however, identified many markets that would be open to using our product without building code approval and are working to market into those areas.
Certainly—from a design standpoint, Lok-N-Blok is capable of being used in any kind of climate.
