How big is a ByBlock?
ByFusion’s Standard ByBlock (BBK-011) is similar in dimension to a standard concrete masonry unit (CMU). – approximately 16″ width x 8″ depth x 8″ height and weigh 22lbs.
Have ByBlocks been tested?
Yes. ByBlocks have undergone independent testing for Compression, Thermal, Acoustic, Fastener Withdrawal and Shear Strength, as well as Environmental screening. Further details can be found in our ByBlock Data Sheet.
ByFusion Global Inc. is committed to ongoing testing, ensuring ByBlock meets International and regional building standards.
If no glues or adhesives are used, what holds ByBlock together?
ByBlock has been designed with interlocking features where the block below fits into the block above. In addition to this, threaded rebar is anchored into your footer or base structure. Each ByBlock is then placed over the threaded rebar and dropped down into position. After your designated height has been achieved, a top plate is placed on top of your final ByBlock course. Using washers and nuts, post-tensioning is applied to the threaded rods which draws the ByBlock wall assembly together into one solid unit.

What about Fire?
Like timber building materials, ByBlock is a Class 5 product. This means it will require a fire retardant in certain applications. These retardants are readily available in the market and are used in everyday building projects.
Upcoming testing strategies include a full array of ASTM fire rating tests based on internationally-accepted standards.
Will ByBlock Float?
Yes. Despite its hefty 22lb weight, ByBlock is buoyant. This is due to the small air pockets which reside between sections of the shredded platic.
How strong do fasteners hold in ByBlock?
ASTM testing results for #10 screw at a depth of 2″ has a strength of 203 lbs/ft Withdrawal Strength, and 270 lbs/ft Shear Strength. Similar tests using a 3/8″ lag screw at a depth of 3″ returned 327 lbs/ft Withdrawal Strength, and 520 lbs/ft Shear Strength.
How is ByBlock different?
If you haven’t yet, go to our ByBlock page to understand the product better.
As a buildng material, ByBlock is intended to work in parallel with standard building products. Unlike concrete block, ByBlock will not crack or crumble, reducing material waste. Additionally, building with ByBlock does not require specialized skills, curing time or mixing of binding agents. This reduces project cost by approx 54% and reduces time of installation by approximately 65% when compared to concrete block.
With excellent thermal and sound insulating properties, ByBlock is a easy and practical use for our unusable plastic waste. Once completed, you cover ByBlock with the finishing of your choice. Therefore, “burying” the plastic in your building project, instead of the landfill.
Can ByBlocks be cut?
Yes. ByBlocks can be cut using standard tools – band saw, reciprocating saw, radial arm saw, chainsaw, etc. with a high tpi count. You can also cut them with a handsaw.
What can I build with ByBlock?
There is no limit to what you can build with ByBlock. As a multi-purpose, high-performing insulating building material, ByBlock can be combined with nearly every standard building product in the market. It sounds corny, but your imagination is the limit.
ByFusion will soon be releasing products into the market. These products include benches and recreational furniture, utility sheds, he/she sheds, retail spaces, and micro homes. Continue to check back or sign up to our newsletter to stay informed.
Can ByBlocks be painted?
Yes. ByBlock can easily be painted using a sprayer or roller application. A specific primer will be required to ensure proper adhesion to the plastic substrate.
Can ByBlock be used for LEED projects?
Absolutely. ByBlock can contribute to LEED credits for your building project.
What about off-gassing?
ByFusion is just as concerned about the environment as you are.
ByBlock is CA Section 01350 Compliant and meets GREENGUARD and GREENGUARD GOLD criteria for formaldehyde, total aldehydes, and CREL/TLV levels.
Testing followed CDPH Standard Method v1.2 “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers” and UL 2821, “GREENGUARD Certification Program Method for Measuring and Evaluating Chemical Emissions from Building Materials, Finishes and Furnishings Using Dynamic Environmental Chambers”.

ByBlock will contribute LEED credits to your building project.
Can ByFusion make custom size byblockS?
Yes. Part of ByFusion’s development is to supply an array of ByBlock in varying shapes to suit a wide variety of applications.
Will ByBlock leach or put microplastics into the environment?
ByBlock is a high-performing, insulating building material and is not intended to be exposed to the elements without an exterior covering. This could be one of any readily available products in the market; weatherboard, stucco, paneling, etc. This will protect ByBlock from weather, UV and any environmental degradation.
Every ByBlock purchase comes with a collection bag for construction debris. Because ByBlock is created using only steam and compression (no melting or extrusion) it is normal to have some pieces fall away when rough handling the material. These can be collected and sent back to ByFusion and we can use the debris to make more ByBlock!
