Durability is the buzzword when talking about any kind of flooring. And replacing a floor is a big investment in time and money, so you really don't want to have to do it that often. With bamboo, that shouldn't be a problem.
One of bamboo's greatest benefits is its durability, its ability to take some abuse and spring back to life. But some types of bamboo are more durable than others based on how the flooring was manufactured.
One of the biggest mistakes people make in selecting their bamboo flooring is focusing too much on cost (which we're all guilty of now and then). Of course, everyone wants a deal and real value for their money, but that's just it. Some less-than-reputable bamboo flooring manufacturers will, on the surface, seem to be giving you a "deal," but the quality with which the flooring was produced makes your hotly sought deal not so hot. The price might be low, but the value matches it. Just like anything…you get what you pay for. Improper processing methods, drying, and gluing, as well as substandard adhesives can all contribute to a low-value product that might look okay on the showroom floor but will not last. So a little research on your manufacturer will really pay off in the long run.
And even if a company processed the bamboo well, there can be variations in the finished products' strength based on the carbonization process all shades except natural color bamboo go through. To get a darker color product, the bamboo shafts are boiled down, and the longer the boil, the darker the bamboo, and the weaker it makes the flooring planks. We're still talking about a quality product, but the darker bamboo will just have different uses. You just might not want to use the darker bamboo in high traffic areas that will take a pounding.
Also though all bamboo is known for its strength and durability, if this attribute is a big one for you, you should consider strand or strand-woven bamboo. Instead of full sections of bamboo being glued and compressed together, shavings and narrow strands of the material are woven together with the adhesive, thus making for an even stronger final product. There is a premium to pay for this level of strength, so it's up to you and your budget to make that call.
In your research to find a durable material for your floor, just do your homework, and remember that it's hard to make a wrong choice with bamboo.
