You might want to think twice about using bamboo in a basement at all. I have seen bamboo explode in some conditions due to excessive humidity. Many manufacturers do not recommend any below grade application with bamboo flooring. If you do choose to install bamboo in this area, be sure to do the proper moisture test, acclimate your flooring properly, and also use a moisture meter to measure the humidity in the area. If necessary, you can use a humidifer or dehumidifer to keep the humidity within the recommened levels.
