Underpinning
RJG Construction, Inc. has specialized in the underpinning of existing structures damaged by earth subsidence for the past 50 years. All methods of underpinning are employed on an as needed basis by RJG. It is important that a specialty underpinning contractor be proficient in all available methods including conventional concrete type methods, as well as manufactured type systems such as helical piles, resistance piles, etc.. In this way our clients are assured that the appropriate method will be employed in the repair of their structure, and that they will not fall victim to a single method type company which may not be appropriate for your project. Additionally, unless an underpinning contractor is thoroughly familiar with all systems available, he cannot accurately judge the feasibility of any particular system over another.
