Research on Prefabricated Composite Drainage Systems of Retaining Walls.

Current research done by the Ohio Department of Transportation (ODOT) analyzes a more cost & time effective, durable, and comparable drainage system than that of the traditional practice of the ODOT. Prefabricated composite drainage systems (PCDS) were used as alternative drainage structures for comparison to traditional systems. Laboratory property testing, application evaluation, and cost analysis was completed to determine the more efficient and usable system. It was determined that PCDS systems cost 40% less than the traditional process and both types of systems have comparable flow and drainage measures. This has caused the ODOT to begin drafting specifications and construction requirements for PCDS systems. PCDS can now be used more commonly in ODOT projects.

To effectively address the Culvert’s drainage challenges at hand, the proposed solution included the drilling of 16 new weep holes, each 26 inches deep, and the insertion of 16 units of the JET Filter 4” diameter open-end drainage system

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.
