Frequently Asked Questions

Yes. We offer: •Mobile labs or jobsite trailers •Satellite curing facilities •On-site testing for fast-paced projects

Yes. We maintain: •Scalable field and lab technician teams •Redundant equipment for surge capacity •Regional support to ensure uninterrupted coverage

Available 24/7, including: •Night pours or weekend shifts •Emergency mobilization •Remote and rural site coverage

•All test data is digitally archived with metadata •Secure cloud-based storage or internal servers •Easily retrievable for project closeouts, litigation, or QA audits

Yes. We can: •Export PDF or Excel reports •Integrate with systems like Procore, e-Builder, or SharePoint •Set up automated report distribution

•Preliminary results: often same-day (e.g., slump test, field density) •Final reports: typically within 24–48 hours •Results are sent via email or uploaded to client portals

Cores are drilled from the pavement, trimmed, and weighed. Density is calculated and compared to design or target compaction specs.

•Marshall: Stability, flow, density, air voids •Superpave (Gyratory Compactor): VMA, VFA, binder content, aggregate gradation •Performance tests (rutting, cracking) may also be included

•Density: Core samples (ASTM D2726) or nuclear gauge •Thickness: Measured directly from extracted core depths

Sieve analysis (ASTM C136) determines the particle size distribution of soils or aggregates. It’s crucial for assessing gradation for concrete, asphalt, or base materials.

•Standard Proctor (ASTM D698): Simulates light compaction •Modified Proctor (ASTM D1557): Uses higher energy to simulate heavy compaction, commonly used for roadway embankments

Using a nuclear density gauge (ASTM D6938) to measure: •Dry density •Moisture content Results are compared against Proctor values to determine percent compaction.

Typically: •Average of 3 consecutive tests: ≥ f’c (design strength) •Individual tests: no more than 500 psi below f’c for strengths > 5000 psi •Projects may have stricter tolerances.

•7-day breaks: within 24 hours after the 7th day •28-day breaks: within 24–48 hours after the 28th day Same-day reporting is often available upon request.

Per ASTM C39, cured cylinders are placed in a hydraulic testing machine and loaded until failure. The max load is divided by the cross-sectional area to determine compressive strength.

Cylinders are cast in standard 6”x12” molds per ASTM C31. They’re stored in a curing box on-site for initial 24 hours, then transported to a lab for curing at 73°F ±3°F until break testing.

•Immediate notification to the client/engineer •Retesting or resampling if needed •Non-conformance reports (NCRs) •Root cause analysis and recommendations

Yes, we provide standardized test report templates with: •Sample ID, test type, method •Results, specifications, remarks •Technician and reviewer signatures

Based on: •Project specifications •Contract documents •DOT or industry standards •Engineer or owner’s quality control plan

•Concrete: Slump, air content, unit weight, temperature, compressive strength •Soil: Proctor density, Atterberg limits, sieve analysis, field density (nuclear gauge) •Asphalt: Core density, Marshall/Superpave, binder content, gradation •Aggregates: Sieve analysis, specific gravity, absorption, LA abrasion

Yes, all tests are performed to standards recognized by local, state, and federal agencies, including DOTs, municipalities, and regulatory authorities.

Yes, we participate in: •AASHTO re:source proficiency sample programs •CCRL inspections •USACE - United States Corp of Engineers •State DOT accreditations ensures quality and consistency.

Labs are certified through programs like A2LA, AASHTO Accreditation and CCRL. Technicians hold certifications such as: •ACI Concrete Field Testing Technician •NICET (Soils, Asphalt) •WAQTC or state DOT certifications

We follow industry-recognized standards, including: •ASTM International (e.g., ASTM C39 for concrete compression) •AASHTO standards (common in DOT work) •Project-specific specs (TxDOT, FAA, Army Corps, etc.)

Testing occurs throughout the project lifecycle: •Pre-construction: material submittals and mix designs •During construction: field sampling and lab testing •Post-construction: final testing for as-builts and quality verification

A certified third-party testing agency typically performs the tests, though sometimes the contractor or the owner hires the testing firm. Engineers and inspectors review results for compliance.

Common materials include: •Concrete (compressive strength, air content, slump) •Soil (compaction, classification, density) •Asphalt (density, gradation, binder content) •Aggregates (sieve analysis, specific gravity) •Steel/Rebar (tensile strength, bend tests)

Construction Material Testing (CMT) ensures that the materials used in construction (concrete, soil, asphalt, steel, etc.) meet required quality, strength, and performance standards. It helps verify compliance with project specifications and ensures long-term structural integrity and safety.
