We are experienced in installing air bags, air plugs, and masonry plugs in submerged pipes. We can provide trained technicians to install a plug and monitor the pressure as needed. We can also dewater the pipes and structures with a variety of dewatering pumps. Our trained divers can install any size cement/mud plug. This can be helpful as a permanent solution, or for long-term jobs.  This will save the cost of monitoring and/or long term rental of airbags or plugs.
