Specialty core sand for foundry work and industrial construction applications.
Material Overview
Core soil, also known as cohesive core material, is a fine-grained, low-permeability soil used as the central impermeable layer in earth structures such as dams, embankments, levees, and containment barriers.
In the construction of earth-fill and rock-fill dams, core soil is placed in the middle section of the structure to form a watertight barrier that prevents water seepage and reduces the risk of internal erosion. The material is spread in thin layers and compacted using heavy equipment, with careful moisture control to maintain effectiveness.
Beyond dams, core soil is used in canal embankments, flood-control levees, landfill liners, and pond embankments — wherever seepage control is critical to the safety and longevity of the structure.
Things to Consider
Low permeability effectively prevents water movement through dams and embankments.
Acts as a barrier against piping, a leading cause of earth dam failure.
Often naturally available near sites, reducing transport costs.
Minimizes water loss in reservoirs, canals, and irrigation systems.
Requires precise moisture control during construction to avoid cracking.
Clay-rich soils can crack when they lose moisture.
Layer-by-layer compaction and quality control increase construction time.
Rainfall or prolonged dry spells can affect construction schedules.
