Scope
What we test in Bloomington
Concrete testing services
Fresh concrete sampled and tested at the pour — slump, air content, unit weight, and temperature — with cylinders and beams cast on site and broken in the laboratory on the schedule your specification calls for.
ASTM C172ASTM C143ASTM C231ASTM C173ASTM C138ASTM C1064ASTM C31ASTM C39
Aggregate testing services
Gradation, fines content, specific gravity and absorption, unit weight, abrasion resistance, and stockpile moisture for concrete, base course, and backfill aggregates.
ASTM D75ASTM C136ASTM C117ASTM C127ASTM C128ASTM C29ASTM C131ASTM C566
Soil compaction and density testing
Standard and modified Proctor curves in the laboratory and in-place density by nuclear gauge on every lift, so fill, subgrade, and trench backfill are documented against the specified percent compaction.
Soil classification and index testing
Sieve and hydrometer gradation, Atterberg limits, moisture content, specific gravity, and USCS classification for earthwork acceptance, select-fill verification, and geotechnical reports.
ASTM D6913ASTM D7928ASTM D1140ASTM D4318ASTM D2216ASTM D854ASTM D2487
Soil corrosivity testing
pH and electrical resistivity of backfill for MSE walls, pipelines, and buried structures, reported against the specification limits for metallic and geosynthetic reinforcement.
Special inspection (IBC Chapter 17)
ICC-certified special inspectors for reinforced concrete and soils, reporting to the building official alongside the materials test results, so one agency covers both requirements.

Local conditions
Construction materials testing conditions in Bloomington
Bloomington sits on glacially deposited soils — silty and sandy materials left behind by the retreat of the Laurentide Ice Sheet — that can vary significantly across a single project site. Add Minnesota's freeze-thaw cycle, which drives pavement and foundation design requirements year-round, and the dense mix of commercial, retail, and infrastructure construction concentrated along the I-494 corridor, and the margin for error in materials quality drops fast. Concrete placed in sub-40°F ambient temperatures demands documented cold-weather precautions per ACI 306; summer pours in the upper Midwest heat require equal discipline on water-cement ratios and curing. Our field technicians, dispatched from the Minneapolis regional hub roughly ten miles away, perform ASTM-compliant testing on concrete, aggregate, and soil — from fresh concrete workability checks and cylinder breaks to Proctor compaction curves and soil classification. Every result is produced under a documented quality system and delivered in clear, defensible reports your project team can act on.
Minnesota's glacially derived soils frequently include fine-grained silts and clays with frost-susceptibility characteristics that require careful classification and compaction verification before and during cold-weather construction windows. Seasonal temperature extremes — from subzero winters to humid summers — place particular demands on concrete mix design documentation and field curing records.
FAQ · Bloomington
How does Minnesota's freeze-thaw climate affect concrete testing requirements on my Bloomington project?
ACI 318 and project specifications for Minnesota typically require air-entrainment in flatwork and structural concrete exposed to freezing conditions. During field testing, technicians verify air content per ASTM C231 or ASTM C173 on every sampling event. Those results, combined with slump (ASTM C143) and temperature (ASTM C1064) readings, document that the mix meets freeze-thaw durability requirements and give you a defensible record if questions arise later.
What cold-weather concrete testing protocols apply when we pour during a Minnesota winter?
When ambient or concrete temperatures fall near or below 40°F, ACI 306R guidelines call for monitoring concrete temperature at placement and tracking curing temperatures over time. Technicians record in-place temperatures alongside standard fresh concrete tests. Cylinder sets intended to verify strength development may require matched curing or field-cured cylinders per ASTM C31 to reflect actual site conditions rather than standard laboratory curing.
Our Bloomington site has variable soils across the footprint — how do you handle Proctor and density testing when conditions change across the site?
When site soils vary in classification or moisture-density behavior, a single Proctor curve (ASTM D698 or ASTM D1557, depending on compaction energy specified) may not be representative of all zones. Technicians can collect representative samples from distinct soil units for separate laboratory Proctors, then reference the correct curve during nuclear gauge or sand-cone density tests (ASTM D6938 or ASTM D1556) performed in each corresponding area.
How fast can a technician be on site in Bloomington?
Bloomington work is dispatched through our Minneapolis, MN regional hub. Scheduled visits are set up by phone at (346) 420-5425; multi-day placements and full-time project assignments are scheduled through a proposal request.
Which office covers materials testing in Bloomington, MN?
Field work in Bloomington is dispatched through the Minneapolis, MN regional hub, about 10 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Bloomington projects.
Are the technicians you send to Bloomington certified?
Yes. Concrete technicians hold ACI Concrete Field Testing Technician Grade I; soils and laboratory technicians hold NICET Construction Materials Testing certifications; special inspection is performed by ICC-certified special inspectors. Where Minnesota agencies or owners require state-specific certifications, those are confirmed in the proposal.
