Damaged Seawall or Bulkhead?

If storms left you with a damaged seawall or bulkhead, we have a solution.

This year’s storm season has taken a major toll on seawalls and bulkheads across the U.S. and Caribbean. Storm surge and flooding can cause erosion not previously experienced under and behind these otherwise sound structures. In some cases, replacement may be the only option if there is a total failure. But often, filling voids behind the wall and sealing cracks or failing joints with structural polyurethane foam will do the job. Seawall repair with foam adds years to the life of your structure without the cost and disruption of excavation.

Bulkheads can be concrete, stone, wood, or metal or synthetic sheet pile. No matter its composition, voids behind the wall can be filled with a Prime Resins product without excavation. Depending on the nature of the job, a number of our polyurethanes have been used successfully to save seawalls. Typically Prime Flex 920 or 910 are the first options, but Precision Lift 4.0# Slow and Prime Flex 985 are also good options for some jobs. Our case studies give some examples.

A recent major project on Padilla Bay in Washington involved saving a rock seawall below five homes. In some places, Homes sit atop a rock seawall that is failing due to erosion. Rock seawall repair with polyurethane uses Prime Flex 920.there were voids more than 10 feet deep. In this case, both Prime Flex 985 and 920 were viable options. Ultimately, the contractor opted for 920 to preserve 500 feet of wall.
