Wave Attenuators/Breakwaters

Our most recent project on wave attenuators was the construction of one of the longest concrete wave attenuator in the United States, for Semiahmoo Marina in Blaine, WA. This wave attenuator is 1035 feet long and it weighs 2.6 million pounds. Each module of our monolithic concrete floats is 12' X 20', and they are connected by heavy-duty steel I-beams. Specially treated wood fences are attached beneath this wave attenuator to help the reduction of incoming waves. This project was completed in only two months.

Mobilization of these huge sections is smoothly done by our marine straddle carrier.

Each connecting steel I-beam is approximately 40 ft long and 2800 lbs in weight.

We did another wave attenuator project in 2000. This extremely strong post-tensioned wave attenuator was built for the Corp. of Engineers on the Columbia River in Washington. It is 180 feet long and 15 feet wide and has approximately 4 feet of draft in the water. It will handle 5-foot waves!

Each pile weldment weighs over 2,000 lbs and can support any wave attenuator.
