America’s Floor Slip Resistance Testing Experts

We’ve tested flooring for the dynamic coefficient of friction (DCOF) and slip resistance all over North America and beyond for around 1,000 individual clients so far as America’s leading independent third-party certified floor friction test lab. We don’t lie in court for slip and fall lawyers (like those who mainly use the Brungraber Mark IIIB, which has no ASTM standard, and no standard in any other country on earth as well), and the English XL tribometer (which has a withdrawn ASTM standard, and no standard in any other country on earth), and we don’t help major American tile manufacturers and floor polishers sell slippery tile and stone to unsuspecting consumers (which is what ANSI A326.3 was designed to do).

We just test floors for slip resistance to get architects, building owners, flooring designers and flooring manufacturers the truth based on internationally-accepted, peer-reviewed science so they can avoid costly slip and fall accidents on properties, and allow people to make informed decisions so they can avoid installing a slippery floor problem. Here’s some photos of us doing floor slip resistance testing around North America and beyond:

Floor Friction Testing in Las Vegas

Floor Friction Testing in Las Vegas, Nevada. They love polished floors in this town, and we’ve tested several of them. We’ve tested plenty of pool decks here, too


Pendulum floor slip resistance testing in Boston – train station, private school pool deck, hotel lobby stairs, etc.


Testing with the pendulum DCOF tester on a pool deck in a multi-million dollar home in Beverly Hills, CA. This pool deck was later featured on an episode of the show Modern Family

Testing floor slip resistance in Florida

Testing floor friction to find the slip resistance of stairs, big box store restrooms, and pool decks on cruise ships all over Florida


Testing floor slip resistance with the BOT-3000e for one of the “big box stores” in Phoenix, AZ. The BOT-3000e, however, shouldn’t be relied upon for getting reliable slip resistance test data on most polished floors, especially polished concrete


Testing stairs with the pendulum tester for a United States Naval Hospital (in the early days of covid-19 when N95 masks were in short supply). We’ve also tested for the U.S. Space Force


Testing a new parking structure with the pendulum tester at LAX International Airport


Testing flooring for slip resistance with the pendulum tester in a mayonnaise factory near Chicago, IL. The look on my face here is because I abhor mayonnaise, and was forced to spend the day surrounded by it

Pendulum Floor Friction Test for City of San Francisco

Testing Floor Friction on bricks of various ages and textures for the City of San Francisco down Market Street

Floor DCOF Testing in Parking Garage

Floor DCOF Testing in a Parking Garage under construction somewhere in the Midwest of the USA many years ago
