U-Drains are available in a wide range of sizes starting from 600 mm to 1500 mm in depth. They come with cover slabs, designed for various load conditions. Drains are factory-made, cast in a closed environment, have superior quality, and are well suited for fast-paced construction.

Based on the topography of the land, the drains will be laid. If the top level of the drain has to be kept flat level irrespective undulations or level differences in the existing ground level, then different depths of the drain have to be chosen to get the required slope. Inner slope for the free flow of water will be achieved by laying Plain Cement Concrete.
If the drain has to be laid as per the topography of the land (Top level of the drain will not be on flat level and varying according to the existing ground level), then there will not be any need for laying Plain Cement Concrete, provided there is enough slope for the water to flow.

A precast RCC U drain, also known as a precast reinforced concrete U-shaped drain, is a drainage structure in the form of a U-shaped channel made from reinforced concrete. It is used to collect and channelize stormwater, rainwater, or wastewater in various applications, such as roads, highways, residential areas, and industrial sites.
• Durability: RCC is a durable material that can withstand heavy loads, erosion, and environmental conditions.
• Quick installation: Precast components can be manufactured off-site and installed rapidly, reducing on-site construction time.
• • Cost-effectiveness: Precast RCC U drains can be cost-effective due to optimized material usage, reduced labor costs, and faster installation.
• • Customization: These drains can be manufactured in various sizes, shapes, and configurations to suit specific project requirements.
• Smooth flow: The U-shaped design of the drain promotes smooth and efficient water flow, preventing blockages and stagnant water.
The standard sizes of precast RCC U drains can vary depending on the region and specific project requirements. Common sizes range from small U drains with dimensions of a few inches to large U drains with widths and depths of several feet. It is advisable to consult local building codes, drainage design guidelines, and the manufacturer's offerings to determine the appropriate sizes for your project.
• Excavation: Trenches are excavated to the required depth and width to accommodate the U-shaped drain.
• Bedding preparation: A suitable bedding material, such as a layer of sand or granular fill, is prepared to provide a stable base for the drain.
• Placement: The precast RCC U drain sections are carefully placed in the trench, ensuring proper alignment and grade.
• Connection: The sections are connected using appropriate jointing techniques, such as tongue-and-groove joints or concrete grouting, to ensure a watertight seal.
• Backfilling: The trench is backfilled with suitable material, compacted in layers, and graded to ensure proper drainage and support around the U drain.
• Surface finishing: The exposed surfaces of the drain can be finished with appropriate coatings or sealants to enhance durability and minimize water absorption.
Precast RCC U drains generally offer good resistance to chemical corrosion. However, the specific resistance can vary depending on factors such as the quality of concrete, environmental conditions, and the presence of aggressive chemicals or contaminants. In cases where the drain is expected to come into contact with aggressive chemicals or wastewater, additional protective coatings or linings may be required. It is important to consider the specific site conditions and consult with engineering professionals to ensure the appropriate corrosion resistance measures are implemented.
