J.F. Brennan Company divers are experienced; underwater construction specialists. Whether it is new
construction, or repair of existing infrastructure, our divers have the right training and equipment to complete a high quality project. Backed by one of the largest fleets of inland marine construction equipment in the United States, there is no project too large or too small that we cannot accomplish.
Our divers are able to repair underwater concrete, steel, and other structures in near zero-visibility conditions. We also have the ability to perform cold-water dives, hot-water dives, contaminated environment dives, and deep dives that require a decompression chamber.
Brennan is a proud member of the Association of Dive Contractors International (ADCI), and all of our commercial divers are certified. We can mobilize anywhere in the continental United States in a timely manner while maintaining competitive rates.
Our divers excel in underwater concrete placement. This includes preplaced aggregate concrete, cast-in-place, and precast concrete. Through the use of several types of formwork, J.F. Brennan Company has successfully repaired ice damaged, degraded, eroded, and broken concrete hidden below the surface of the water. We are also able to repair underwater steel structures. Specialty equipment such as underwater saws, torches, and welders enable our trained divers to remove or repair steel structures such as pipes, gate structures, trash racks, outfalls, etc.
