What We Do
“Soil construction is the only area of construction conducted by assumptions and trial & error compromise”

ESOL is a specialized geo-civil consulting group that solves major engineering and construction deficiencies, and brings significant business value to owners, designers, builders, concessionaires and the “smart compactor” industry. ESOL fills historical gaps between the geotechnical sector and the designers and builders in the industry. Due to these gaps, designers and builders have no reliable ability to control soil construction and build infrastructure fills to design requirements. ESOL provides that unprecedented ability and solves the most pervasive and costly problems plaguing design and construction. ESOL has successfully served hundreds of projects across the nation.

Historically, designers and builders have relied on assumptions and trial & error compromise in fill design and construction. Though inadvertent, these process conditions serve as the primary source of the greatest problem in infrastructure. These conditions escalate construction costs and result in ground movement from strength loss, settlements, and shrink swell problems. ESOL corrects these deficiencies, and solves these core problems which prevail today:

These ground movement problems drive the performance and maintenance warranties in construction contracts, and the heavily litigated earth movement exclusions in CGL (commercial general liability) policies carried by construction contractors. ESOL solves this with the performance, cost and liability controls all parties need by replacing the assumptions and compromise with site-specific determinations and verification. ESOL solves the primary source of the majority of the historic ground movement problems in infrastructure. ESOL also fills a critical gap in the use of “smart compactors.”

ESOL gives owners, designers and builders unprecedented control over the foundations of their projects -- by replacing process assumptions with determinations and verification -- in the everyday design and construction of infrastructure fills.

Historically, geotechnical engineers determine or assume how strong fills need to be, but do not provide connection or control for that in construction. Instead, design engineers are inadvertently provided with process control assumptions that, in reality, prevent achievement of design requirements in construction. Design requirements not achieved as believed include strength stability, permeability requirements, and shrink-swell control. These assumptions also cause process control problems during construction, which impedes production. ESOL fills this gap without changing industry compaction standards or affecting geotechnical testing services. ESOL provides total solution of the compaction control problems that plague the industry. See typical project results compared to the results of all other projects.

  • ESOL directly serves owners, regulatory agencies, design firms, environmental firms, architects, contractors, design-build firms, geotechnical firms, concessionaires, construction managers, insurance companies, and the construction litigation bar.
  • ESOL indirectly serves all compactor manufacturers and fills critical gaps in the “smart compactor” industry.

Some Additional Detail

Founding earthen fills are the only element of infrastructure design and construction that is conducted by assumptions, trial & error compromise, no real-time control, and no direct data verification. These conditions yield deficient subgrade fills unrealized in the industry. The central problem with that is, fills are foundations of our infrastructure, and infrastructure is expensive. These deficiencies include 1) deficient soil construction, 2) excessive construction costs, 3) deficient service life, and 4) excessive maintenance & repair costs. Because of these deficiencies, the earthworks element of construction is what generally dictates construction contracts, construction warranties, maintenance warranties, insurance coverage exclusions and premiums, and construction liability separation on projects.

  • Deficient Construction - The greatest problem in infrastructure is differential foundation movements occurring from strength loss, settlements and shrink-swell problems from moisture change primarily in the fill elements of our foundations. These problems are the primary cause of US property damages now amounting to $19 billion annually and escalating by $350 million each year. Most of this damage comes from the fill elements of our foundations more than from natural subsurface soils, because underlying in-situ soil conditions are conservatively managed in design, and fills are a common remedial component of this management. (See “The Most Critical Components of Ground Risk.”) These conditions result because the specified compaction standards are not achieved in construction as engineers traditionally assume, and strength properties are unknown and highly variable. ESOL provides the controls needed to prevent these problems, with real-time control and verification. Without ESOL's controls, these foundational problems will continue to occur and escalate.
  • Excessive Construction Costs - The traditional assumptions made in all process control methods force trial & error compromise during fill construction. Trial & error exercises include reference lab “curve shopping”, field “data shopping”, new reference curves, false compaction moistures, lift reworks, etc. These trial & error exercises are required because traditional control references conflict with the mechanical performance of the compactors used in construction. This condition forces compactor operators to try to perform differently than the compactor does - a mechanical impossibility. All of these trial & error exercises cost time and money, and cause adverse compaction. ESOL provides the controls needed to avoid costly trial & error and maximize production. ESOL serves all process control methods used today.
  • Deficient Service Life/Excessive Maintenance & Repair Costs - Our pavements and foundations are plagued by differential movement caused by saturation settlements and shrink/swell conditions during moisture changes. These conditions usually start developing about 2-5 years after construction. These conditions lead to eccentric loading on structures, structural damage, uneven and failing pavements. These conditions are progressive and can limit service life greatly and often require excessive maintenance and repair early on. ESOL provides the controls needed to minimize or eliminate these conditions, maximize service life, and minimize maintenance needs.
