Geotechnical Engineering

LANDTEC provides geotechnical engineering services for some truly innovative projects. We partner with civil and structural engineers to assess site and soil conditions and, ultimately, provide design recommendations and lasting engineering solutions for: 

— urban mixed-use developments & hotels
— master planned communities & residential developments
— sports stadiums & ballparks
— entertainment complexes
— roadways, interchanges & bridges
— schools & education facilities
— distribution centers
— water / wastewater treatment plants
