BSL can provide economical solutions in accordance with international standards to improve the engineering properties of soil to mitigate the potential damage caused by the use of unsuitable soils in foundations. Most soils used as backfill materials are obtained from nearby riverbed that carry untreated wastewater from industries and other chemical pollutants from city wastewater. This can result in efflorescence in brick masonry foundations and is a major cause of deterioration of concrete and steel in subsoil RCC structures. BSL offers cheap soil stabilization techniques for long-term durability and protection for brick and concrete in contact with soil for residential, commercial, and industrial buildings.
