Jet Grouting

Jet Grouting is a highly effective ground improvement method that creates stabilized soil-cement columns through high-pressure fluid injection. Pacific Foundation offers advanced Jet Grouting solutions for a wide array of soil conditions, project complexities, and market sectors—including civil, commercial, industrial, infrastructure, and government. Our specialized equipment fleet, deep technical expertise, and collaboration with an associated geotechnical engineering firm (Pacific Structural Solutions) enable us to deliver reliable, cost-effective solutions that meet stringent project requirements.

Technical Expertise

• Diverse Ground Conditions
  Our team has successfully applied Jet Grouting techniques across a wide range of soil profiles, from loose sands to stiff clays. By leveraging advanced equipment—including rigs from Bauer, Klemm, Casagrande, Hütte—and field-proven processes, we tailor each jet grout column design to address specific load, stability, and permeability requirements.
• Multiple Jet Grouting Methods
  We are experienced in implementing a range of jet grouting systems, choosing the most suitable approach based on subsurface conditions, project constraints, and performance targets.
• High-Precision Column Installation
  We regularly install vertical and battered (angled) jet grout columns to address unique project demands, including utilities protection, cutoff walls, slope stabilization, and foundation enhancements.

Notable Projects

• Sand Island WWTP (Synagro) – Honolulu, HI
  Challenge: The project site was directly above a main wastewater utility, requiring a specialized approach to protect existing infrastructure.
  Solution: We engineered a unique solution, deploying battered jet grout columns and used the existing thrust block to support the utility while creating a water cutoff seal. This approach preserved utility integrity and maintained continuous plant operations under tight spatial constraints.
• Kings Village (Ka Haku Tower) – Oahu, HI
  Challenge: Create a CDSM bottom seal below the water table while also controlling for settlement and foundation support in highly variable subsurface conditions.
  Solution: Tailored Jet Grouting and soil mixing  to improve ground stability and mitigate settlement risks, leveraging detailed soil data to optimize column spacing and diameter.
• Mainland Projects
  We have completed numerous high-profile Jet Grouting projects across California, Idaho, Washington, and Oregon. Our long-standing relationships with public agencies, private developers, and general contractors attest to the reliability and efficiency of our ground improvement solutions.

Key Advantages

• Integrated Geotechnical Support
  Through Pacific Structural Solutions, we have direct access to geotechnical engineering expertise. This synergy improves project planning, design execution, and real-time adaptation in the field.
• Advanced Equipment Fleet
  Our Bauer, Klemm, Casagrande, and Hütte rigs, combined with specially trained crews, provide the flexibility to tackle a broad range of geologic and site-specific challenges.
• Regulatory Compliance & Industry Involvement
  As a member of ADSC and other professional associations, we maintain strict adherence to industry standards and best practices, ensuring high-quality, compliant project outcomes.
• Geographic Reach
  Operating across the mainland United States (CA, ID, WA, OR) and Hawaii, we mobilize rapidly to support both regional and remote projects with minimal downtime.
