A bamboo composite timber and method for making the same is presented. Bamboo slats are laid up into a preform in a mold and coated with a urethane adhesive. The slats are arranged in the preform in side-to-side, end-to-end and face-to-face orientation. The composite is subjected to elevated temperature and pressure in the mold until the adhesive cures, the temperature and pressure ensuring uniformity of the resulting timber and eliminating voids and the like internally. The slats may be arranged in any of numerous ways, including three directions of orthogonal relationships.
