Driesenga & Associates' geotechnical team is skilled in conducting a wide range of geotechnical investigations, from simple one-story residential, commercial or industrial facilities, to multi-story structures, dams, highways, bridges, retaining walls and more.
With our client-focused approach, we work closely with you in order to fully understand the type of development and related structural loads proposed for a site. Then, based on a scope of services that we customize to your needs, we obtain data to form recommendations for site preparation and construction procedures, as well as for foundation, retaining wall, floor slab, and pavement design.
We work hard to maintain strong relationships with stakeholders and to provide top-tier service, which is why our comprehensive reports can be relied on by municipal agencies, state agencies, architects, structural engineers, developers, and the community.
Our geotechnical services include but are not limited to:
• Soil borings
• Shallow foundation, floor slab and below-grade wall recommendations
• Deep foundation including helical piles, auger cast piles, driven piles, etc.
• Ground improvement such as vibro-compaction, rammed aggregate piers, etc.
