Natural fibrous materials such as coir, jute and kenaf have been used as reinforcement to increase the compressive strength of soft soil. This study introduces a new natural fibrous material namely rattan as the reinforcement for soft soil. The main objective is to determine the compressive failure of soft soil reinforced with rattan. Unconfined Compression Test was conducted according to BS1377-7:1990 standard testing procedures. The first series of testing was conducted on inclusion of different content of rattan strip (0 %, 0.5 %, 1.0 %, 1.5 % and 2.0 %) in soft soil. The second testing series is conducted on inclusion of different length of rattan strip (2 cm, 3 cm, 4 cm, 5 cm and 6 cm) in soft soil. The samples are all prepared at optimum moisture content (27 %) and maximum dry density (1.435 Mg/cm 3 ). Mix performances were obtained where inclusion of rattan can be either beneficial or detrimental depending on the content and the length of the rattan. Rattan fiber of 0.5 % and length of 4 cm seems to be the optimum value in achieving higher compressive strength. Generally, the reinforced soil using rattan strip shows more plastic and ductile behavior.
