Full-Service Geotechnical Materials Testing Laboratory

The single most important deliverable of a geotechnical laboratory is accurate test results — period.
That’s why companies consistently rely on our lab… to make sure their work is exactly right.

Tom Burdick Alpha Omega Geotech lab manager

Our lab supervisor, Tom Burdick, is a long-time expert in local soil and rock materials and is often a lifeline for designers planning projects.

Materials Testing

We’ve spent decades sifting through soil and rock materials in and around Kansas City and that often allows us to jump-start projects with gut instincts because we know what builders are up against. Our test results give project leaders the insight they need to make decisions with fewer risks.

Soil Testing

The soil in and around Kansas City is not the same as the soil in other parts of the country. We have a lot of clay in our area, as well as rock materials in various formations. Soil testing can shine a light on potential problems with the ground you plan to build on. Land thought to be sufficiently solid can turn out soft under scientific scrutiny. Crucial soil inconsistencies and variations are also routinely uncovered. Only accurate test results from a trusted lab can prove the need for design adjustments or replacement soil and all of the associated costs.
