Many facing block and geosynthetic reinforcement choices are available to the designer of segmental block-faced geosynthetic walls. Because of the newness and rapid growth of this industry, technology development has lagged behind implementation, leaving the designer without all the tools necessary for wall design and material selection. The key issues that must be addressed to properly design and specify a segmental block-faced geosynthetic wall are discussed, including selection of block size and geometry, selection and spacing of geosynthetic reinforcement, selection of design parameters (including wall face connection strength), the effect of seismic loads on the wall system, and wall specifications. Research is recommended for poorly defined aspects of segmental block-faced geosynthetic wall design.
