Michigan DOT and Jet Filter System completed a successful 2-year product demonstration of Maintainable Weep Hole Filters. These results are now published on the AASHTO Product Evaluation List under DOT Evaluated Products

AASHTO stands for American Association of State Highway and Transportation Officials. The organization provides guidance and standards for construction products for America’s transportation infrastructure.

Every year, new products are developed to improve roads and bridges, reduce construction costs and provide longer service life.

Michigan DOT & Jet Filter Systems installed 52 weep hole filters into the exterior walls of a twin-barrel box culvert running under US-31 along the Macatawa North Branch. The demonstration project tested multiple filter sizes, configurations, and filter fabrics. Based on the results, Michigan DOT published a state-wide special provision allowing for the use of Maintainable Weep Hole Filters on any new or existing retaining wall.

What is a Weep Hole? Enhancing Drainage and Soil Stability with the Jet Filter Weep Hole System

Weep holes are critical elements in various construction materials including concrete, steel sheet piles, and vinyl walls. They serve a fundamental purpose in managing water within structures, particularly in preventing accumulation that can lead to structural damage or increased hydrostatic pressure. While traditionally associated with moisture control, weep holes also play a vital role in soil retention and stability.
