Controlled low strength material requires an approved what when used for shallow foundations?

Controlled low strength material (CLSM) is often used in construction for applications such as backfilling and as a lightweight fill material. When utilizing CLSM for shallow foundations, a geotechnical report is essential. This report provides critical information about soil properties, site conditions, and the overall suitability of the material for the specific application.

The geotechnical report helps assess the load-bearing capacity of the soil, identifies potential settlement issues, and ensures that the use of CLSM will satisfy engineering requirements. It is based on site-specific data and lab testing, which help determine how the material behaves in the context of local conditions.

Having an approved geotechnical report ensures that the foundation design and materials used comply with safety standards and building codes, ultimately enhancing the structural integrity and durability of the foundation.
