Frequently Asked Questions About Diamond Surface Inc.
What services does Diamond Surface Inc. provide?
Diamond Surface Inc. is a full-service concrete pavement restoration and rehabilitation contractor. Core services include diamond grinding, bridge deck grinding, Next Generation Concrete Surface (NGCS), close-proximity and specialty grinding, joint sealing, dowel bar retrofits, and full- or partial-depth concrete repairs.
What geographic areas does Diamond Surface Inc. serve?

Why choose diamond grinding over traditional asphalt overlays?
Unlike asphalt overlays that wear down over time and increase maintenance costs and road noise, diamond grinding is a long-lasting, sustainable solution that restores smoothness, increases skid resistance, reduces tire-pavement noise, and extends the overall service life of concrete roadways.
What is Next Generation Concrete Surface (NGCS)?
Next Generation Concrete Surface (NGCS) is an advanced texture design that provides a smooth, quiet ride on concrete pavements. It is specifically designed to significantly reduce highway noise while improving safety and surface friction.
Where is Diamond Surface Inc. located?
Corporate headquarters are located at 21025 Commerce Blvd, Ste 900, Rogers, MN 55374. DSI also maintains regional shop facilities in Big Lake, Minnesota, and Huxley, Iowa.
What is diamond grinding, and how does it extend concrete pavement life?
Diamond grinding uses specialized machines equipped with closely spaced diamond saw blades to shave off a micro-layer of concrete, leveling faulting, curling, and surface irregularities. By restoring a smooth riding surface and reducing dynamic vehicle impact, diamond grinding can extend pavement service life by 8 to 17+ years without damaging joints or compromising structural integrity.
How does diamond grinding differ from concrete milling or scarifying?
Unlike cold milling—which uses impact tools that chip and micro-fracture concrete, often causing spalling at joints—diamond grinding is a precise, smooth cutting process. It leaves uniform longitudinal grooves that reduce road noise, enhance skid resistance, and prevent joint damage.
What are the primary benefits of bridge deck grinding and profiling?
Bridge deck grinding removes surface bumps, corrects cross-slopes, and prepares bridge surfaces for protective overlays or final rideability standards. It improves surface traction, eliminates water-pooling areas, and ensures smoother transitions between bridge spans and approach roadways.
What types of projects does Diamond Surface Inc. handle?
Diamond Surface Inc. provides nationwide specialty concrete pavement restoration (CPR) services for state Departments of Transportation (DOTs), airport runways, local municipalities, commercial roadways, and general contractors. Core capabilities include diamond grinding, bridge deck profiling, Next Generation Concrete Surface (NGCS) techniques, dowel bar retrofits, joint sealing, and full-depth concrete repairs.
Is diamond grinding a cost-effective alternative to complete pavement replacement?
Yes. Diamond grinding is a fraction of the cost of total pavement reconstruction or thick asphalt overlays. Because it targets surface defects directly and requires shorter lane closure times, it significantly lowers project costs and reduces traffic disruption for surrounding communities.
How is slurry managed during diamond grinding operations?
DSI grinding equipment utilizes high-efficiency continuous vacuum recovery systems. Concrete slurry generated during wet grinding is immediately vacuumed off the road surface and transferred directly into slurry tankers for proper environmental handling, containment, or approved discharge according to state DOT regulations.
