YJACK | Malaysian Brand | World Patents | The World’s Best Pile Load Test

YJACK is a world patented innovation to carry out static bi-directional (BD) pile load test. It is an alternative and economical method to conventional maintained load test (MLT) using kentledge blocks or reaction piles. The platform technology of YJACK is adopting a flat jack (or multiple jacks) to conduct BD pile tests on all pile types, from small loading driven concrete piles to large loading cast in-situ bored piles, as well as offshore marine piles, reinventing the bi-directional pile load test to enjoy low cost and work safe but equal to conventional top loaded MLT test results. 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.
