Cut-Off Walls for Storage Tanks & Silos

Waterproof barriers to protect foundations and substructures

Cut-off walls are underground barriers that control water flow and seepage beneath storage tanks and silos. These structures often sit on sites with high groundwater or variable soil conditions. By limiting water migration, cut-off walls help secure stable and dry foundation conditions, reducing risk of settlement, erosion and structural damage. VSL offers cut-off wall solutions tailored to storage tank and silo projects to improve durability and performance.

Why cut-off walls are key for tanks and silos

Storage tanks and silos often face challenges from high groundwater, subsoil seepage or fluctuating water tables. These conditions can lead to soil erosion under slabs, uneven settlement and compromised structural integrity. Cut-off walls act as waterproof subsoil barriers that prevent water flow and protect foundations. By maintaining controlled and dry ground conditions, these walls enhance long-term stability and help meet safety and performance targets.

Cut-off walls limit water movement below ground. This reduces seepage toward critical foundation elements.

By controlling subsoil water, these walls reduce the risk of uneven settlement. This supports long-term structural performance.

Walls can be designed for varied groundwater levels and soil types. This allows customization per project needs.

Controlled groundwater conditions help prolong foundation life. This lowers long-term repair and maintenance needs.

Cut-off walls work with slab-on-grade and improved soil systems. This supports a robust overall foundation solution.
