Geotechnical Exploration & Soil Testing Services

Are you looking for soil testing services in the St. Louis area? QTE explores below the surface of your potential site to arm your design professionals with the necessary data to provide you with the quality foundation you need to last the lifetime of your project. QTE is flexible enough to work with you to generate as much data as you require.

With decades of combined experience, our skilled team of geotechnical engineers, field staff, laboratory technicians, licensed geologists and certified scientist provide geotechnical services including field explorations, laboratory testing and foundation and site development recommendations. QTE’s geotechnical engineers are also trained to respond to a wide range of emergency situation soil-related issues including:

• Failure Analysis and Corrective Action Recommendations
• Soil Stabilization, Slopes and Sinkholes
• Retaining Walls and Foundations

QTE explores the subsurface conditions to provide your design professionals with critical data for shallow and deep foundation design, ground improvement methods, seismic analysis, and flexible and rigid pavement design. QTE also performs global stability analyses of cut or fill slopes, which may include retaining walls. Our field staff has the experience and certifications to carry your project beyond the design phase and through construction.  Our firm is one of just a few accredited testing laboratories in Southern Illinois.

QTE also performs Environmental Testing & Consulting and Construction Materials Testing.

Construction Monitoring

• Foundation observation
• Controlled engineering fill density testing
• Settlement monitoring
• Soil stabilization recommendation and monitoring

St Louis Soil Testing Services For Construction

St Louis contractors count on Quality Testing & Engineering when they need a geotechnical engineer or soil engineers who stand behind their work. Whether your construction project involves installing septic systems, pouring foundations or any other application, QTE can help.

Quality Testing and Engineering’s O’Fallon, IL and St Louis, MO offices can help you with your subsurface exploration requirements. We employ traditional drill rig technology as well as rotary air drill and can assist with test pits.

QTE uses in-house labs to conduct geotechnical testing. We can assist with triaxial compression testing, permeability testing, shear strength testing soil density and soil compaction testing as well as monitoring soil conditions. We can help with liquid limit or Atterberg limits testing, unconfined compression, swell pressure, consolidation, resistivity grain size distributions tests and Proctor compaction tests.

We work with all types of soil to determine moisture content and to help you determine what types of structures soil can support.

Builders in the St Louis area know that they can stand by our site development recommendations for shallow foundations, auger cast piles, drilled piers, rammed aggregate piers, seismic design considerations, settlement potential, determining soils ph level, shrink-swell potential and other considerations. We are experts at determining influence of groundwater on design construction as well as suitability of on site soils for structural fill. We can help you determine engineering criteria for placement of structural fill as well as making pavement sub-grade recommendations.

Our team of structural engineers, geologists and technicians have been advising on commercial and home build projects for decades. Consider QTE for soil sample analysis and soil construction analysis in the St Louis and Southern Illinois area.
