NEW DEVELOPMENT – CAVITY GROUTING, AL JUBAIL, KSA

Ground Treatment for a new development using cavity grouting

New residential development near Al Jubail – KSA suffered from severe ground settlement in multiple locations during the construction stage. The excessive settlement stopped the activities on site and led to a delay in the delivery date.
Viridi was assigned the task to investigate the reason for the settlement and propose a remedial measure that can be implemented in a short time. In order to understand the root cause of the problem, additional ground investigation and cavity mapping using Ground penetrating radar surveys were taken place on site. Interpretive report for the cavity mapping was prepared including the ground treatment proposal (Cavity grouting). The treatment recommendation included a design of low carbon grout mix, setting the technical requirements for the treatment work including the QA/QC work and the initial Inspection and Testing Plan (ITP).
During the ground treatment execution, Viridi was involved in supervising the grouting work and ensuring achieving the technical requirements, managing the post cavity mapping work and issuing the closing recommendations.
