Bi-Directional Pile Load Test using YJACK Technology

Bi-Directional Pile Load Test using OTHER Technology

Effective Self Compactions

Effective self compactions from upper concrete above jacks to compact lower concrete to gain higher unit fs and fb

Less Self Compactions

Less self compactions from upper concrete above jacks to compact lower concrete to gain low unit fs and fb

Solid Concrete Layers

Failing soil sediments trapped above conical jacks will be flushed up during concreting, solid concrete layers formed  

Soft Concrete Layers

Soil sediments trapped above steel plates unable to be flushed up during concreting, soft concrete layers formed

Easy Flush Up

Conical jacks to easy the concrete to be flushed up the soil sediments below the jacks to form solid concrete layers

Difficulity Flush Up

Steel plates to blockage the concrete to be flushed up the soil sediments below jacks to form soft concrete layers

Intact Pile Integrity

Cross-hole sonic logging pile integrity testing detects sound and intact pile integrity prior to YJACK pile test

Damaged Pile Integrity

Cross-hole sonic logging pile integrity testing may detects pile damaged in between steel plates prior to pile test

Easy Post Grouting

Post grouting can be fully recovered the load transfer area on gap opening in split zone

Difficult Post Grouting

Post grouting is difficult to be recovered the load transfer area between steel plate with contaminated concrete
