THE INVENTION OF SANDJACKINGTM Like all great inventions, SandjackingTM was born out of necessity.  In 1993, Chuck Asplin, reluctant to replace concrete in great condition but needing a solution to address the problem of his sinking sidewalk, tapped into his knowledge as an Army engineer and 40-plus years in the construction industry for a better solution.  He reasoned that if he could lift the concrete, filling it with sand would not only be an immediate solution, but a permanent one as well. Working to repair the sidewalk, Chuck soon found himself the center of a neighborhood spectacle and, after the job was complete, he had five requests to do the same work on other homes. Thus, the SandjackingTM  process was born and has been honed to provide the quickest and most cost effective solution to address concrete problems.  Chuck developed all the processes and equipment used and holds five patents covering the various aspects of lifting and filling.
