Shoring/Soil Nailing
Soil nailing, soldier pile & lagging,
secant piling, tangent piling, underpinning - All are methods
utilized to successfully retain earthen slopes and neighboring
structures adjacent to excavations. Each technique has its
advantages and not all methods are appropriate for all sites.
Soil conditions, ultimate use of the site and its shoring,
schedule, and coordination with other operations such as excavation
and form work weigh heavily in the selection of the most appropriate
technology. Condon-Johnson & Associates (CJA) is pleased
to participate in the pre-engineering assessment of a project
to assist in the selection of the most appropriate technology.
CJA has consistently introduced new technology
into the field of shoring. CJA performed the first soil nailing
project in North America in 1976, and was the first to use
soil/cement mixing (DMM) methods in earth retention projects.
Tiebacks to depths of 270’and excavation and shoring
depths of 114’ have been achieved. Using the latest
operating equipment, CJA continually looks for opportunities
to improve this market sector.
