Subsurface Constructors built its reputation with drilled foundations in the Midwest, but has expanded into a complete foundation engineering and construction corporation. Our experience in drilled foundation construction, continual investment in technology, and a culture of process improvement has made Subsurface Constructors the region’s recognized leader in our industry.

Subsurface has a large fleet of foundation drilling equipment ranging from drill rigs specially suited for tight areas with limited overhead space to high-torque drill rigs capable of excavating competent rock at high production rates. The variety of machinery we own gives us the confidence and ability to offer the most practical and cost-effective means for installing drilled foundations on a project.

Some of Subsurface’s drilled pier capabilities include:

• Drilling depths up to 160 feet
• Drilling diameters up to 12 feet
• High production rock excavation
• Low overhead restrictions / tight rig access
• Slurry Drilling
• Load Testing / Osterberg Cells
