Portadam offers an effective method of surrounding an in-water remediation site and separating the clean water from the work area while maintaining natural stream flow. In addition, by working in a dry area, excavated material dewatering is minimized.

This cofferdam method is clean and reusable, making it the most desirable and cost effective product for use in a multi-phase remediation project while offering clear, unobstructed access to the work area (lake or river bed.) No fill material is typically required, therefore the customer does not add more contaminated materials to the site to be remediated.
