Geotechnical Investigations

Tier One Engineering conducts detailed geotechnical investigations to assess subsurface conditions, informing foundation design, site preparation, and risk mitigation for civil projects. Our integrated approach combines field exploration, laboratory testing, and expert analysis to support safe, cost-effective construction.

Scope of Our Investigations

• Subsurface Exploration: We perform borings, standard penetration tests, cone penetrometer tests, and sampling to characterize soil, groundwater, and rock conditions.
• Foundation Recommendations: We provide guidance on footings, piles, slabs, or soil improvement techniques like grouting or stabilization.
• Site-Specific Analysis: We evaluate slope stability, settlement, seismic risks, and fill requirements for roads, retaining walls, or other structures.
• Environmental Considerations: We identify potential issues like contamination, sinkholes, or expansive soils to mitigate future risks.

Geophysical Testing Expertise

Our non-invasive geophysical methods deliver accurate subsurface insights:

• Seismic Refraction: Measures wave velocities to identify layer transitions and excavatability.
• Ground Penetrating Radar (GPR): Provides high-resolution imaging for voids, utilities, or reinforcement near the surface.
• Electrical Resistivity: Maps moisture, leaks, or fractures using electrode arrays.

Our licensed engineers deliver comprehensive reports with data, design recommendations, and construction guidance. Using advanced technology and a safety-first approach, Tier One Engineering lays a solid foundation for enduring projects. Contact us to explore your site’s subsurface with confidence.
