Installing a new wood floor? Instead of traditional hardwood, you may want to consider an eco-friendly alternative: bamboo. It may be hard to imagine that reedy green plant growing wild in your yard making a good flooring material, but some varieties of bamboo (when mature and properly dried) are as hard as oak–and some are even harder.

Green Depot carries bamboo flooring by Foundations, a New York state-based company that offers click-together “floating” strand boards, as well as traditional tongue-and-groove solid-strip options, both in prefinished and unfinished varieties. Foundation’s strand planks are made of the Moso variety of bamboo, which proves to be two times harder than red oak when subjected to the industry-standard Janka ball test. And Moso isn’t a natural food supply for a pandas, so harvesting it even in the wild doesn’t endanger their habitat.
But why else is bamboo such a good choice? The reasons are many, beginning with bamboo’s rapid renewability, which makes it one of the greenest of green products used in building. A tree takes 80 to 120 years to grow to a size where it can be harvested for hardwood flooring planks, but a bamboo plant reaches maturity in only 3 to 6 years with minimal (if any) fertilization or pesticides, and it renews itself without replanting. This means it requires not only fewer natural resources to thrive, but less labor, as well. And bamboo can easily grow up to a foot a day, so it’s not just fast, but plentiful.

Bamboo is also a boon to the natural environment itself, in a number of ways. Mature bamboo has a very complex and dense root structure (which, incidentally, is why is can be so hard to get out of your garden), which goes a long way to avoid soil erosion in areas where it’s planted. Furthermore, a bamboo forest absorbs up to twice as much carbon dioxide as trees.
From a social responsibility perspective, as well, bamboo is winner—600 million people worldwide depend on income from it, and the industry employs nearly 6 million people in China alone. And as it grows in popularity, those numbers only expand.
Then there’s affordability, which ties back to bamboo’s ability to renew itself rapidly. The laws of supply and demand are at work here: A product that springs back into place quickly and with so little effort and expense can easily be kept in abundant supply, so prices for it can be lower, even in times of great demand. And its durability gives it another layer of affordability, as many kinds of bamboo flooring can go for long periods without refinishing or replacement. Several brands, including Foundations, coat their pre-finished planks with multiple layers of a water-based, zero-VOC, aluminum oxide-infused polyurethane that doesn’t off-gas at all. Nice!
And that’s not even touching on the design options bamboo flooring offers. Bamboo is available in any number of colors, many of which can be achieved using eco-friendly methods. Heating bamboo makes it darken to a rich amber color without the use of stain, and bleaching it in non-toxic hydrogen peroxide gives it a birchlike white-blond color. Its natural tone is a warm golden hue that lies somewhere in between the two, and bamboo can be colored with traditional wood stains to take it to anywhere from a medium chestnut brown to a near-black ebony.
Bamboo’s narrow-strand structure allows it to be pressed into planks in a number of different formats, unlike wood, which of course comes naturally bound into wide pieces (tree trunks). Some bamboo flooring manufacturers even offer planks made of mixed dark- and light-colored strands, for an unusual streaky look. Still others turn the plant’s fibers the short way, so the cut ends of the stalks are what make up the visible surface. The effect is a sort of small-dot pattern that is unique to bamboo.
As a side note, Green Depot also carries Plybam, an excellent companion to bamboo flooring. Plybam is plywood made entirely of bamboo instead of wood veneer, and it’s perfect for use in cabinetry, furniture, paneling or any other project that usually calls for plywood. Its edges have a multidirectional pattern that offers an alternative to plywood’s striped edges, and is attractive enough to make edge veneers a thing of the past.
