YJACK - Pile Testing

What is YJACK YJACK is the trademark of the product to carry out bi-directional ( BD) pile test in static load pile bearing testing ( SL) . It is an alternative and economical method to conventional maintained load test using reaction piles or kentledge blocks methods. The core technology of YJACK is adopting a flat jack ( or multiple jacks) to conduct BD pile tests on all pile types such as drive/ jack-in close ended reinforced concrete piles, open ended and offshore piles well as cast in-situ micro-API and bored piles. The flat jack, which due to its physical shape, is the most suited for use in BD pile test, with cheaper cost and better performance.
