Services
Geotechnical Engineering
Our geotechnical engineering services include subsurface investigations, foundation design, and site stability assessments. We analyze soil and rock properties to provide tailored solutions for commercial, residential, and industrial projects. Our engineers use advanced tools like the Marchetti Flat Plate Dilatometer to ensure accurate settlement predictions.
Construction Materials Testing
We perform comprehensive testing of construction materials including soil, concrete, masonry, and asphalt. Our certified technicians conduct field and laboratory tests to verify compliance with project specifications and building codes. Services include compaction testing and structural steel inspections.
Drilling Services
Our in-house drilling services support geotechnical investigations using two all-terrain drill rigs. We collect soil and rock samples for analysis, providing critical data for foundation design and earthwork planning across North Carolina and beyond.
Laboratory Testing
Our AAP-accredited laboratory conducts soil, concrete, and aggregate testing following ASTM standards. Services include triaxial testing, permeability analysis, and compressive strength evaluations to ensure material quality meets project requirements.
Special Inspections
We provide continuous special inspections for soils, foundations, and structural elements in accordance with local building codes. Our certified inspectors ensure construction practices meet regulatory requirements and project specifications.
