JMT’s commercial divers possess the knowledge and equipment to review and evaluate the structural integrity of assets with underwater components. Our divers are qualified to work in confined spaces and perform underwater penetration in accordance with OSHA regulations.  

Project types include: 

  • Bridges, tunnels, and culverts 
  • Ports, terminals, piers, and bulkheads 
  • Locks and dams 
  • Storage tanks 
  • Treatment facilities
