Why Do You Need Ripley's Dams?
   When ground water invades a pipe trench, it will flow down the slope, creating an under ground river. This flow erodes the back fill and creates voids. When a load passes over the pipeline, it could cause a collapse of the fill. If you have the dams in the ground it will prevent this from happening

Why Choose Ripley's

  • Stops sinkholes
  • Prevents dips in the road that where contaminated
  • Keeps Wetlands Wet
  • Safe and easy to install
