Why do I Need a Geotechnical Report before Foundation Repair?

A geotechnical report is a vital investment for any foundation repair project because it provides the essential subsurface data required for a safe and effective design. This report avoids the risks of under-design and costly setbacks by ensuring the repair strategy is based on actual site conditions rather than guesswork.

The primary reasons you need a geotechnical report include:

• Identifying Soil Characteristics: The report analyzes soil type (such as Denver’s prevalent expansive clays), bearing capacity, and groundwater levels. These factors determine the required load transfer depth and the specific repair approach needed.
• Guiding Solution Selection: Accurate data allows engineers to match your soil conditions to the correct advanced earth anchoring systems, such as choosing between helical piers for low-bearing soils or push piers for heavier loads.
• Ensuring Code Compliance: Local building codes (IBC and IRC) and ICC-ES acceptance criteria (AC358) typically require a geotechnical report to prove that the repair design meets minimum standards for load-bearing capacity and settlement potential.
• Preventing Failure: By providing precise bearing capacity data, the report helps prevent foundation pile failure and ensures the long-term stability of the repair.
