Broadcast Capping System

Our patented Broadcast Capping System (BCS™) has been used to place sand covers, engineered caps, and light armament on over 1,200 acres of subaqueous sediments. We have succesfully placed GAC mixtures, Aquagate, Organoclay, and sand covers in a number of waterbodies throughout the United States.  This system is highly efficient and has led to substantial cost savings to our clients.

Mechanical Capping & Sand Cover Placement 

Brennan can also install a sand cover or cap the traditional way, through mechanical methods. Using excavators or cranes outfitted with RTK-GPS and sophisticated placement software, our operators can place material in a variety of conditions, depths, and thicknesses.
