ASI develops an effective repair method to seal a leaky joint. ASI successfully developed a patented Underwater Self-sealing Grout after research indicated there were no off-the-shelf grouting or mechanical technologies available to seal a leaky joint in a deep ocean outfall. The patented Underwater Self-sealing can be readily pumped through 305 m/1000 ft. of 2 cm/0.75 in. diameter hose without plugging, unlike “standard” commercial mixes with chemical additives.

ASI’s team developed the patented grout as a solution to seal several leaks of an outfall as part of an annual inspection project in Ponce, Puerto Rico. The repair required remotely operated vehicle (ROV) deployment for reasons of safety, cost efficiency, water depth and extreme distance from the nearest manhole. Deep water section of the outfall (115 m/376 ft. deep) in The Ponce Deep Ocean Outfall had leaks that were inaccessible from the outside as they were covered in grout mattresses.
