PND’s marine experience extends to the inland waterways of our nation where we recognize the importance of maintaining and improving these critical transportation routes. Ranging from the Yukon River of Alaska to the great Mississippi, PND has provided designs for docks, wave barriers, erosion control, and a host of other solutions.
PND’s experience with northern region river systems translates well to our nation’s other river systems. High seismic activity, ice breakup flooding, and permafrost conditions have led to solutions using partially penetrating wave and diversion structures and OPEN CELL® bulkheads for large vertical loads and wall heights.
