Lime slurry is a suspension of calcium hydroxide in water. The product is a user-friendly, cost-effective alkali. Lime slurry is a free-flowing product that is used for a variety of industrial, municipal and environmental applications. The product is also used extensively for the stabilization of expansive clay soils.
A trench is excavated to create a form for each wall, then filled with slurry; it is kept full of slurry at all times. The slurry prevents the trench from collapsing by providing outward pressure which balances the inward hydraulic forces and prevents water flow into the trench. Reinforcement is then lowered in and the trench is filled with concrete, which displaces the slurry. Slurry walls are typically constructed by starting with a set of guide walls, typically 1 metre (3.3 ft) deep and 0.5 metre (1.6 ft) thick.
