Yes, bamboo x-treme decking is commonly used around swimming pool areas.  As with any wooden product used outdoors, there is always a risk of formation of splinters. However, splinters from bamboo x-treme decking are normally smaller than (tropical) hard wood splinters. Any splintering can be sanded off for a smoother finish, if desired. A regular application of oil (more frequently around swimming pools) is recommended to reduce the formation of splinters. Regular maintenance with a silicium carbide broom/disk or brushing/light sanding is suggested to effectively remove splinters and smoothen the surface.
