Alta SouthwestMaterial Testing

ALTA works with architects, engineers, owners, general contractors, and any other participants throughout each phase of a project to verify that the materials used during construction comply with the project specifications. Proper selection, quality, and workmanship of materials is vital to ensure today’s buildings and infrastructure perform to standards over long time periods. Our services can save clients significant amounts of money by preventing change orders during construction as well as reducing future maintenance and repair costs.

ALTA can provide systematic testing and inspection services to ensure material specifications and sustainability goals are achieved. ALTA engineers work closely with clients to minimize material replacements, reduce the likelihood of deterioration, avoid potential failures, and investigate and evaluate materials-related problems and failures when they do occur.

Material TestingServices Detailed

ALTA can provide a wide range of services during construction and operates several materials testing laboratories under current industry standards. We can also mobilize to provide the materials testing you need, where you need it, when you need it. Once construction is underway, our extensive experience and innovative thinking allows us to help our clients deal with challenges in a practical, hands-on manner to keep their project on track. Services include:

Field sampling and testing of fill materials placed for support of structural site components. Typically includes field density testing, field proctor testing, moisture determination, observations of lift thickness and verification of compactive effort and soil types used.

Typically includes observations, sampling and testing of soils (disturbed and undisturbed) for determination of engineering properties related to bearing capacity (foundation support) for proposed structures.

Compaction testing, rolling patterns, temperature, and thickness verification of asphaltic concrete (asphalt) materials for roadways, drives and parking areas.

Sampling and testing of fresh concrete for verification of material properties including unit weight, slump, air content, and temperature typically performed during placement on a project site.

Retaining Wall Monitoring and Certification includes monitoring of segmental retaining wall construction including drainage, geo-composite installation, material properties, and other key information utilized for certification of construction practices for the wall structure.

Utilized for determination of quantities of borrow soils, unsuitable soil, stone, asphalt, rock, and other materials typically for payment verification or estimating purposes.

Includes the evaluation of existing soil conditions and recommendations for remediation or suitability for proposed construction.

Utilized to determine the required aggregate, cement, water, admixtures and/or additives for concrete products based on their required use.

Preparation of mix designs and recommendations for chemical stabilization utilizing lime and cement based on actual site conditions and project requirements.
