What is Surcharge?

A surcharge load, typically consisting of fill material, placed on the design platform. This surcharge load, together with the platform fill, exerts pressures on the underlying soft soil and creates development of excess pore water pressures that are slow to dissipate due to the low permeability of these soft soils.
