Public owners and regulators need control over public expenses, assurance of their engineering standards and infrastructure needs, minimal maintenance costs, and minimal risk. Only the design & construction of foundation subgrades jeopardizes these needs. ESOL resolves the typical subgrade problems and minimizes subgrade risks. ESOL fulfills these needs and gives public owners unprecedented control, with the following benefits:

• Typical deficiencies of subgrade fill construction are remedied
• Design standards of practice (compaction standards and strength requirements) achieved in construction of foundation fills
• Agency compaction standards achieved in construction with direct data verification
• Stable infrastructure foundations and pavements
• stable subgrade strength during wetting and saturation
• no more saturation settlements
• controlled and minimized shrink-swell conditions
• No more inadvertent engineering compromise forced in construction
• Secure ability to design foundations and pavements with known subgrade strength & stability properties
• Greatly extended service life
• Minimized or eliminated maintenance & repair costs
• Higher production/reduced construction costs
• Cost/schedule/performance risk removed from area of highest construction risk
• Preempting change order risk
• Reduced construction warranty costs
• As-built construction records with direct verification of fill elements
