results for this questionWhich is the best way to overcome buoyancy in concrete?Which is the best way to overcome buoyancy in concrete?One method that is used to overcome buoyancy is to increase the concretes mass (m).This is accomplished by increasing member thickness (i.e.walls and slabs).Increasing the thickness of the walls and slabs can add a significant downward gravitational force but this may not always be the best bang for your buck.NPCA Buoyancy White Paper Section 1- Buoyancy Guide(Buoyancy) When Precast Concrete
