In this paper, mechanical properties of jet-grouted soilcrete are investigated. Jet grouting (JSG) was conducted to improve ground properties for the construction of a cross-passage between a sewerage tunnel and a manhole of the Taipei Sewer Sub-main System. Soils treated were silty sand and sandy silt. Cylindrical specimens were drilled from the site and tested in the laboratory. Experimental results show that the elastic wave velocities, modulus of elasticity, and uniaxial compressive strength of soilcrete increase with increasing dry density. Poisson's ratio of soilcrete varies from 0.05 to 0.29, which is very close to the ratio for concrete. Brazilian tensile strength of soilcrete varies from 1/7 to 1/28 of its uniaxial compressive strength. The cohesion of jet-grouted soilcrete varies from 0.40 to 4.22 MPa, and the internal friction angle varies from 20° to 44°. The design internal friction angle φ= 0° recommended by the JSG Association appears to be conservative.
