Research 2006: To Mitigate Problems in Bi-Directional Technology to Reduce System Failures
Finding 2010: Patented Flat Jack (YJACK) and Removal of Steel Plates to Remove Soft Layers
YJACK Research
Effective self compactions from upper concrete above jacks to compact lower concrete to gain higher unit fs and fb
Less self compactions from upper concrete above jacks to compact lower concrete to gain low unit fs and fb
Failing soil sediments trapped above conical jacks will be flushed up during concreting, solid concrete layers formed
Soil sediments trapped above steel plates unable to be flushed up during concreting, soft concrete layers formed
Conical jacks to easy the concrete to be flushed up the soil sediments below the jacks to form solid concrete layers
Steel plates to blockage the concrete to be flushed up the soil sediments below jacks to form soft concrete layers
Cross-hole sonic logging pile integrity testing detects sound and intact pile integrity prior to YJACK pile test
Cross-hole sonic logging pile integrity testing may detects pile damaged in between steel plates prior to pile test
Post grouting can be fully recovered the load transfer area on gap opening in split zone
Post grouting is difficult to be recovered the load transfer area between steel plate with contaminated concrete
Those that spearhead YJACK have 30 years experience in managing as well as developing a business suited to the pile testing industry
We have operations in multiple countries that give us a wide scope of experience in different geotechnical environments and regions
Our world patents allow us to maintain technology that is unique to us and is able to solve problems that the bi-directional testing industry encounters through our own jack technology
The exclusion of the steel plates allow the YJACK to significantly reduce the risk of soft layers forming around the jack and create an overall more reliable and accurate system
We are looking for distributors and markets in many other countries to continue making a difference in the pile testing world and continue the dream of being the world's best pile test
We employ a young and dynamic team that is willing to go the distance for the company and contribute ideas as well as time to make sure the company is able to achieve our sustainability goals
