Janka Hardness Scale
What makes Fossilized® Flooring so hard?
Choosing a Hardwood
When it comes to choosing the best hardwood flooring option for your commercial or residential project, there are a number of factors to consider: color, style, material, installation methods, the list goes on. At the top of the list for most is durability. But how do you determine how durable a floor is without testing it in your home? As the saying goes, the proof is in the pudding and in the case of flooring, the pudding is a floor’s Janka score.
The Janka Hardness Scale
The Janka hardness scale, used to determine whether or not a wood species is suitable for flooring, is the primary test measuring wood’s resistance to wear and dentability. How does the test work? The Janka test measures the force required to embed an 11.28mm steel ball halfway into a piece of wood. The higher the amount of force needed, the higher the Janka score and the more durable the wood.

How It's Made
The Cali Bamboo Fossilized® Process
What is it that makes Cali Bamboo’s Fossilized® bamboo flooring the hardest floors in the world? It’s all in the proprietary process Cali Bamboo Fossilized® flooring undergoes:
Step 1. Bamboo Strips
Starting with 5-7 year old Moso bamboo, the poles are harvested at the peak of their strength. The poles are then split using a blade the resembles an apple cutter. The strips are then run through a machine that removes the outer green skin. The bamboo is then placed on a drying rack that goes into a kiln and is heated over several days until the bamboo reaches an optimal moisture content of 5%. Next, the racks of dried bamboo are dipped into an ultra-low VOC adhesive and are now ready to be pressed.
Step 2. Compression
The coated bamboo strips are loaded into a vertical press in stacks about 3 feet high. The high pressure hydraulic press crushes and compresses the bamboo into a block about 12 inches tall.
Step 3. Milling
The blocks of solid bamboo run through a saw and are cut into boards. Next, the boards are run through a laser guided milling machine where they then become either click-lock or tongue and groove flooring. The planks are then sanded and are ready to be finished.
Step 4. 10-Coat Finish
In a separate clean facility, the new bamboo planks make their way through the Cali Bamboo® 10-Coat Durability Sealing System.
