Marine Repair

The Judy Company has over 80 years of experience in structural stabilization and foundation work, including engineering and contractor services related to drilling and grouting for marine repair.

In a recent project, The Judy Company‘s geotechnical staff decided to use a fast setting sodium silicate-cement grout to perform a marine repair on an eroding breakwater in the Milwaukee Harbor for the Corps of Engineers. The marine repair project was contracted at a total value of $2.4 million dollars and was completed more than a month earlier than scheduled. Alternative marine repair proposals from other companies, using new steel sheet pilings to encapsulate the existing structures, ranged within $50 to $60 million.

As a marine repair solution to the deteriorating break water, a two-phase grouting concept was used. Phase one was accomplished by drilling approximately 3200 holes in the concrete cap. 2600 cubic yards of quick-set grout was injected along the outer edge of the structure to form a barrier wall. The quick-set grout was formed by the combination of a sodium silicate solution and a cement solution, which became a solid in less than one minute. Phase two used the quick-set barrier walls as a means of confining the second type of grout, a sand/cement grout, of which 9,250 cubic yards were injected into the center of the structure to fill the remaining void.

Over the years, The Judy Company has developed a reputation for performing quality work and has generated a good rapport with government agencies, industry, utilities, other contractors and engineers. Contact us today and let us help you with your next marine repair project.
