Materials Engineering, Construction Testing & Environmental Services

As a registered Professional and Consulting Engineering firm, and certified by the Indiana Department of Transportation and a prequalified designer by the Public Works Certification Board for the Department of Administration for the State of Indiana, GEOTILL places the highest priority on properly defining and understanding our clients’ needs. Accordingly, we use a project team approach to evaluate all aspects of a client’s project. Our staff of professional engineers, project managers, and certified technicians collectively has many years of experience in foundation and geotechnical engineering and materials testing projects.

GEOTILL’s staff is committed to resolving the foundation and geotechnical-related problems all the way through construction services and materials testing confronting our clients actively, economically, efficiently, and with minimum interruption to normal routine.

GEOTILL is unique for the ability to offer engineering and testing package services that allow our clients more control, continuity, and a cost-effective solutions to their projects.

GEOTILL routinely provides geotechnical evaluations, site exploration, and materials testing and consulting to small and large construction, engineering, architectural, retail, and development firms, as well as local governmental agencies.

Traditional Geotechnical Services

 Geotill’s traditional geotechnical services include projects range from basic footing inspections to complex geotechnical evaluations. They include engineering analyses and design recommendations for shallow (spread footings and mat foundations) and deep (auger-cast, drilled pier, driven piles, aggregate columns, stone columns) foundation systems, and earth retention systems including drilled pier, sheetpile walls, slurry walls, braced excavations, segmental, soldier pile, soil nail, MSE and modular block walls, large block walls and stone gravity retaining walls.  Our geotechnical personnel are also experienced with site development including site grading, construction of engineered fills and retention systems, and infrastructure improvements, including water and sewer lines.

Instrumentation Geotechnical Services

 Our instrumentation geotechnical services include instrumentation for tieback installation, settlement monitoring, deep foundation load testing, slope inclinometer monitoring, vibrating wire piezometers, settlement cells and earth pressure cells.  Our staff has experience in instrumentation, installation, commissioning of geotechnical instruments, knowledge of Instrumentation Geo-Control Systems and IT.

Drilling Services

GEOTILL’s Geotechnical Drilling and environmental soils drilling services provide accurate, reliable information in a cost effective manner.

Environmental Services

GEOTILL is a full-service environmental consulting firm based in Indiana. The environmental services include Phase I & Phase II environmental site assessments, building decontamination, Investigation & Remediation Services.

Construction & Concrete Testing

Concrete and aggregate testing plays a vital role in the construction project by providing owners, designers, and contractors with valuable information throughout a project’s progress. GEOTILL operates fully equipped, state-of-the-art concrete testing laboratories specifically devoted to the testing and analysis of cementious materials. We provide mortar testing, sand testing, concrete testing, aggregate testing, and stone testing services.

In order verify that the materials used during construction such as backfill compaction  and other related testing comply with the project specifications. Geotill is capable to respond quickly to ever-changing construction needs and schedules. We respond with innovative solutions and alternatives that target your long-term performance objectives while considering cost consequences.
