Generally, bamboo x-treme decking won’t warp, buckle or crack to the extent that most other timber decking tends to. Bamboo x-treme decking boards are very uniform in size and nature, due to the production process. Over time, some cracks on the surface and on the end of the boards can arise from the different drying characteristics of the surface and cross-cut ends. This does not affect the stability or durability of the board. The surface of the boards will tend to get a little rougher over time and may form (small) splinters as a result of continuous water absorption and desorption due to dry and wet weather periods. Dimensional change or cupping of the boards can occur after installation, but less so than most other decking products. These phenomena are normal for most hardwood species and Bamboo X-treme decking.  Any rough patches or surface cracking can normally be easily smoothed off with a light sanding or brushing – this is best done prior to oiling the decking too.
