The National Authority on Pressure Grouting Standards, Compliance, and Engineering Oversight
Advancing safe, code-compliant pressure grouting practices through engineering standards, research, testing, and enforcement guidance across the United States.
Pressure Grouting Standards
National guidance for code-aligned pressure grouting practices supporting infrastructure, foundation, and slab stabilization applications.
Research, Testing & Data
Independent research, material science context, and verified testing benchmarks informing engineering-led decision-making.
Resources
Curated technical references, code excerpts, and supporting documentation for pressure grouting evaluation and review.
Setting the Standard for Pressure Grouting in the United States
US Pressure Grouting Administrations (USPGA) exists to establish clarity, accountability, and technical integrity within the pressure grouting and slab stabilization industry.
Our mission is to support engineers, agencies, contractors, and asset owners with verified engineering data, code-aligned methodologies, and transparent performance standards.
“Pressure grouting is not a product or a shortcut. It is an engineered process that must be designed, executed, and verified in accordance with recognized codes and performance standards.”
— USPGA Technical Advisor
Why Engineering Oversight and Code Compliance Matter
Pressure grouting plays a critical role in pavement stabilization, foundation support, void filling, and structural rehabilitation. When performed without engineering oversight or code compliance, it introduces risk, premature failure, and liability. USPGA was formed to help provide information and resources to help ensure that pressure grouting applications across the United States align with International Building Code (IBC) requirements, Department of Transportation (DOT) specifications, and established geotechnical engineering principles .
Engineering & Compliance Support
Pressure grouting applications often involve structural and regulatory considerations where independent technical review is required. US Pressure Grouting Administrations (USPGA) provides neutral, standards-focused engineering guidance when questions arise around documentation, testing results, or code alignment.
