1. Project Navigator’s Sediments and Sludges Experience
Project Navigator’s team has managed projects over the past five years where enormous volumes of impacted materials have been handled in a cost-effective manner.
In all these projects, we have strived to only excavate what is absolutely necessary to achieve protectiveness, thereby generating cost savings for our clients.
