Remote Access

Through out the years, as our client's needs have changed, TG&B has  adapted and provided sampling platforms and techniques to address those needs.  More recently, those requirements have included remote access sampling sites.  TG&B  specializes in providing innovative and versatile  sampling approaches.  Our smaller more maneuverable platforms are used to collect samples where access is an issue and boat ramps are unavailable.

We can design and build a customized platform to meet your remote access needs - please inquire.
