Innovative Geocomposite to Reinforce Marginal Fill Soils in Southern Ontario

maccaferri logo

Reinforced soil slopes in Canada are typically constructed using free draining soils.

Low permeability and cohesive soils (marginal fill soils) are usually avoided for use in reinforced soil applications due to low shear strength and excessive pore pressure build up associated with the compaction of these soils.

The use of marginal fill soils for reinforced slope construction would allow for significant cost savings on projects where high quality fills are not readily available.

Read Maccaferri paper on the use of the innovative geocomposite to reinforce marginal fill soils, which combines reinforcement and drainage characteristics in a single geogrid. This paper will discuss the first applications of this innovative geocomposite in Southern Ontario.
