Soils & Engineering Services, Inc. (SES) is a family-owned and operated consulting engineering firm located in Madison, Wisconsin. We have been serving clients on projects located in the Madison area, as well as throughout Wisconsin, upper Michigan, northern Illinois, and eastern Iowa since the company was started on April 1, 1966. We are a certified Minority Business Enterprise (MBE) and Disadvantaged Business Enterprise (DBE).

SES is a consulting engineering firm specializing in geotechnical and environmental services; monitoring well and piezometer installations; geotechnical and environmental drilling and sampling; and materials testing of soils, aggregate, concrete, hot-mix asphalt, emulsified asphalt, masonry blocks, and bricks.

Our staff includes engineers, technicians, drillers and administrative support personnel. We have seven drilling rigs plus field and laboratory testing equipment. Our laboratory is AASHTO-accredited for testing concrete, aggregate, and hot-mix asphalt. We are a WisDOT-approved laboratory for testing soils, concrete, aggregate, and hot-mix asphalt.

Our project experience includes testing concrete and base course materials under the Wisconsin Department of Transportation (WisDOT) Quality Management Program (QMP) for bridges, culverts, and roadways. We provide quality assurance testing for other engineering firms on airport construction projects for runways, taxiways, and aprons. This work includes testing concrete, asphalt, base course, and subgrade materials both on-site and in our laboratory.

Testing

Sampling and testing of soils, aggregate, concrete, asphalt cement, hot-mix asphalt, emulsified asphalt, mortar, masonry units, concrete pavers, bricks, concrete beams, and silo staves.
Compaction (field density) testing using nuclear density test gauges or sand cone methods.
Moisture-density test curves, modified and standard Proctor methods.
Laboratory testing methods include: California Bearing Ratio, Atterberg limits, moisture content, organic content by loss on ignition, particle size distribution using hydrometer and sieve methods, rate of consolidation, compacted permeability rates, falling head permeability rates, constant head permeability rates, fracture count, freeze-thaw durability, L. A. Abrasion, and sodium sulfate soundness.
AASHTO-certified laboratory for soil, concrete, aggregate, and hot-mix asphalt.
WisDOT-approved laboratory.
QMP testing on WisDOT projects including concrete and aggregate base course, and field density of hot-mix asphalt pavement and MSE wall backfill.
Field and laboratory technicians certified through the Highway Technician Certification Program for WisDOT QMP projects.
Double-ring infiltrometer testing (for in-situ rate of permeability) .
Slug testing of monitoring wells and piezometers (for in-situ rate of permeability) .


Engineering Services

Work scope preparation for geotechnical services based on discussions with our clients and the project proposed.
Foundation type recommendations (shallow spread footings, drilled shafts, driven pilings, micropiles, push-piles, soil nailing, rammed aggregate piers, etc.) based on the soil and bedrock conditions encountered and the proposed structures.
