The possibility of pipe flotation is often overlooked when designing underground pipe systems and roadway culverts. Understanding buoyancy is important when installing storm drainage structures and pipe. Applying the theory of buoyancy to the installation and maintenance of storm drainage has proven beneficial in the asset management process. We will address the theory of pipe buoyancy, susceptible scenarios for pipe flotation, and two recognized methods for calculating pipe flotation potential. We will close by identifying several best practices to prevent buoyancy from impacting culverts.
