Portadam® cofferdams eliminate the need for expensive floating equipment by allowing your excavator to have direct access to the river bed. Pipeline river crossings may be completed "in the dry" with a simple two-phase operation. Pipeline anomalies can be isolated and repaired with minimal equipment or disturbance to the surrounding terrain. Drill, blast, excavate, construct or repair "in the dry" without unlawful earthen dikes or costly sheet piling. Call us for a free site assessment which includes an inwater survey, historical flow data review, site engineering and design. Portadam® has worked successfully with pipeline contractors for over a quarter century.
