The reinforcement is placed at the base of the embankment and used to increase stability and resistance to foundation failures. Advantages include an increased design global safety factor without sacrificing embankment height and differential settlement is also reduced. This technique is applicable to new embankment and widening over unstable soils.</p><p>
