Surface Preparation Technologies LLC

SPT is the nation’s most experienced, reliable rumble strips contractor for shoulder and centerline rumble strips. SPT has cut over 150,000 miles of shoulder rumble strips and centerline rumble strips in every state combating drift-off highway crashes.

The reason our competitors have only a fraction of our experience is simple — they haven’t been competitive. Our customers know that when you factor in our production, uncontested reliability, and hundreds of thousands of miles in cutting experience, SPT always offers the lowest cost option.

Rumble strips are often the final item on your construction schedule. Installation time must be fast, accurate and reliable. Nobody in the industry can meet these requirements like SPT.
