Marine Construction
Heavy marine construction diving for 60 years has provided Logan Diving & Salvage with the experience, knowledge, and resources to support your diving related project needs.
Commercial divers trained in underwater burning and welding speed your falsework installation and removal.
Sheet pile underwater cut off to elevation is accomplished with underwater burning utilizing exothermic rods. Underwater burning is available for mild steel, stainless steel, aluminum, concrete, and cast iron.
Bridge construction underwater cement or grout placement is available for footers, seal pours, columns, piers, and standard forms. Cement is pumped, poured or tremied in any depth of water regardless of current or visibility.
Logan Diving & Salvage's divers understand steel, timber, concrete, and aluminum in an underwater environment. Diving support of general contractors involved in heavy construction is a valuable portion of our business and we welcome the opportunity to be of service.
