What geotechnical engineering services does Kiwa provide through Raba Kistner?

Kiwa delivers comprehensive geotechnical engineering services including subsurface soil and rock testing, laboratory testing, foundation engineering, pavement and subgrade evaluations, slope stability analysis, and groundwater and geohazard studies.

Why are geotechnical investigations important before construction begins?

Geotechnical investigations help identify underground risks early so project teams can reduce the chance of structural failures, construction delays, cost overruns, pavement distress, and long-term maintenance issues.

What types of projects has Raba Kistner supported with geotechnical expertise?

Raba Kistner has supported a wide range of projects, including retail centers, sports arenas, airports, energy transmission systems, levees, federal infrastructure, highways, and other complex or high-risk developments.

Geotechnical Engineering: Building on Certainty - Trusted Subsurface Expertise for Every Project

Subsurface conditions influence the safety, performance, and long‑term durability of every structure. Through Raba Kistner, Kiwa delivers industry‑leading Geotechnical Engineering services that help project teams understand underground risks, optimize designs, and build with confidence. Our geotechnical specialists combine decades of regional experience with one of the largest archives of geotechnical data in the Southwest, enabling highly accurate evaluations across diverse soil and rock conditions.

What We Do

Kiwa provides comprehensive geotechnical investigation and engineering services, including:

Subsurface soil & rock testing
Geotechnical drilling, in situ testing, and sample collection to characterize soil and rock conditions for design and construction.
Laboratory soil & rock testing - Classification, consolidation, strength, compaction, and specialized testing performed in accredited labs.
Foundation engineering - Recommendations for shallow and deep foundations, settlement analysis, and bearing capacity evaluations.
Pavement and subgrade evaluations - Geotechnical input for pavement design, rehabilitation, and performance assessments.
Slope stability & earth structure analysis - Evaluations for embankments, retaining structures, levees, and dams.
Groundwater and geohazard studies - Groundwater behavior, seepage, and risk assessments for expansive soils, coastal sands, and rock formations.

Our teams have supported projects ranging from retail centers and sports arenas to airports, energy transmission systems, levees, and federal infrastructure; bringing proven expertise to complex and high‑risk environments.

Why Geotechnical Expertise Matters

Uncertain or misunderstood subsurface conditions can lead to:

Structural failures
Construction delays
Cost overruns
Pavement distress
Long‑term maintenance issues

High‑quality geotechnical engineering reduces these risks by revealing potential challenges early and guiding design decisions that improve safety, performance, and cost efficiency.
