Innovators in Drainage Structure Repair & Maintenance

At Subsurface Inc., we’ve always believed there had to be a better, more cost-effective way to address drainage structure issues. Growing up in the earthmoving business, we spent years removing and replacing countless drainage structures, often asking ourselves—why not rehabilitate instead of replace?

Like an iceberg, the real challenges in infrastructure lie beneath the surface. With our extensive background in open-cut excavation, we sought innovative solutions to restore aging drainage systems without the high costs and disruption of traditional methods. The answer? Trenchless technology.

With over 80 years of combined experience in both traditional construction and advanced trenchless repair methods, Subsurface Inc. delivers smarter, more efficient solutions for infrastructure rehabilitation. Our approach is simple: Do what’s best for the customer—not what’s easiest for the contractor.
