U-Drains & Cable Trenches: Durable, Customizable, Efficient Solutions. AVSTech offers versatile U-Drains that not only serve as effective stormwater drains but also function as cable trenches. Our pre-casting process ensures precise, easy installation with customizable solutions tailored to your specific needs. For added convenience, we offer weep holes for efficient water runoff and insert plates for cable segmentation, making it perfect for both stormwater management and cable infrastructure. Our U-Drains are made with high-strength concrete, cast using a low water-to-cement (w/c) ratio in advanced precast molds. Pre-placed rebar is securely embedded, and the concrete is vibrated to ensure a strong, homogeneous structure with no trapped air. We also offer the option for coring or incorporating hole formers for added flexibility. Once stripped, the mold is reused for further efficiency.
