We would like to introduce a case where "Grundmart" was implemented in ground reinforcement and support piles. This involves the construction of driving piles down to the supporting layer during building. It is used as an easy method for ground reinforcement during new construction and for support piles in earthquake recovery work. Additionally, it is also possible to insert commercially available single pipes into the holes created by Grundmart. 【Case Studies】 ■ Ground Reinforcement Work ■ Support Pile Work *For more details, please refer to the PDF materials or feel free to contact us.
