How Bluff Drains Work

Animation of diverted groundwater draining into Lake Michigan.

Diverted groundwater drains into Lake Michigan 10 feet above the beach at rates as much as 120 gallons per hour, helping to prevent bluff failure.

The Bluff Drain Process

Each property is different and requires a unique solution to prevent bluff failure. Through wise use of technology, such as horizontal directional drilling (HDD) and innovative drain materials, Gillen’s system adapts well to many bluffside properties.

Gillen consults with licensed professional geotechnical engineers to analyze each situation. These experts use their knowledge of the area and methods such as soil borings to determine the best solution. Bluff drains are sometimes used in combination with stone shoreline revetments to prevent landslides and stabilize bluffs.

Bluff Drains Process—Patent Pending

Patented bluff stabilization drains offer an efficient, cost-effective solution. Internal groundwater is removed, preventing further erosion due to seepage and weight.

Your property can be stabilized and your investment protected.
