LT Concrete Box Culvert | Precast Box Culvert Selangor

Product Description

The LT Concrete Box Culvert is a premium precast solution engineered for high-capacity water management and structural crossings in civil engineering projects. Designed for maximum durability and load-bearing performance, these culverts are essential for major infrastructure, including road crossings, tunnels, and large-scale storm drains.

1. Box Culvert W/O DWF: A standard flat-bottom invert for general drainage.
2. Box Culvert W DWF: Featuring an integrated Dry Weather Flow (DWF) channel to maintain velocity during low-flow periods, preventing siltation and buildup.

Key Features & Benefits

• Modular Versatility: Available in nominal sizes ranging from $300\text{ mm} \times 300\text{ mm}$ up to a massive $2100\text{ mm} \times 2100\text{ mm}$ capacity.

• Heavy-Duty Performance: Engineered for significant structural loads, with the largest inverts weighing up to 3.22 tonnes. 

• Precision Engineering: Manufactured with a standard length of one (1) metre for consistent alignment and fast installation.

• Integrated DWF Channel: The "W DWF" option features a specific channel (C and d dimensions) to optimize hydraulic performance during dry spells.

• Rebate Joint System: Features a 12 mm rebate design to ensure tight, reliable connections between units.

• Stormwater Management: Designed to channel large volumes of surface water, making it ideal for main monsoon drains in urban and residential areas. 
• Structural Crossings: High wall thicknesses (up to 165mm) and heavy-duty weights (up to 3.22 tonnes) allow these units to be used for road crossings and underpasses. 
• Infrastructure & Civil Works: Suitable for highway drainage, airport runway runoff systems, and industrial estate water management. 
• Low-Flow Hygiene: The "W DWF" (With Dry Weather Flow) version is specifically designed for areas where preventing stagnant water and silt buildup is a priority during dry seasons. 
• Modular Construction: Each unit is a standard 1-metre length, allowing for rapid, sequential installation for long-distance culverting. 

• Invert & Lid System: The box culvert is an assembly of a base (Invert) and a top cover (Lid), which allows for easier transport and installation compared to monolithic structures. 
• Joint Integrity: Features a 12mm rebate design to ensure a secure and stable connection between the lid and the invert. 
• Size Versatility: With internal widths ranging from 300mm to 2100mm, it can be applied to everything from small utility trenches to massive subterranean drainage networks.
