Protect your storm drains with the patented design that seals tight and won't rip. Guaranteed.
  • Long-lasting -- great for outdoor deployment without worrying about degradation
  • PIG Tough -- top layer resists stretching, ripping, tearing and infrared light
  • Super-sealing -- bottom layer conforms to uneven surfaces and tightly seals drains
  • Diesel-compatible -- withstands prolonged exposure to diesel fuel and gasoline
  • Use cover for quick spill response or long-term, outdoor deployment
  • Eliminates the need to frequently deploy and remove a temporary cover or permanently seal your drains
  • Ideal for drain protection where liquid transfers, washdowns or other leak- and spill-prone jobs are common
  • DuPont Elvaloy technology provides lifelong flexibility plus chemical, UV and infrared light resistance to vinyl top
  • High-visibility yellow top layer draws attention to spills for increased safety
  • Includes a nylon storage bag for easy transportation and fast spill response
  • Need a custom size? Call 1-800-HOT-HOGS (468-4647)

Spill stopper

We have deployed these around the perimeter of our facility at each storm drain. Incase of a spill, we can put these down to prevent anything from getting into the storm drains. They have worked without incident in testing / drills.

This drain blocker is far above others. This material is reusable and stops liquid immediately. It does everything as advertised and more!

Drain cover

We purchased this to cover a trap we don't want water getting into. Since we have installed it we have cleaned the floor numerous times even with a pressure washer and no water has gotten past the mat. Excellent product!
