NDS Dura Slope Trench Drains

NDS Dura Slope Trench Drains

Efficient water control is critical in residential and commercial settings, and NDS Dura Slope Trench Drains deliver long-lasting performance across a wide range of applications. They help prevent flooding, reduce erosion, and keep outdoor surfaces safe and functional year-round.

Engineered from high-density polyethylene (HDPE), these lightweight yet durable systems feature an integral 0.7% slope, interlocking joints, and built-in rebar clips, offering reliable surface drainage with minimal maintenance. The material resists corrosion and cracking, making it ideal for areas exposed to the elements.

Designed to manage stormwater runoff efficiently, Dura Slope Channel Drains are ideal for driveways, loading docks, and parking lots. They outperform traditional concrete drains by reducing installation time and improving flow rates. Whether you're upgrading a commercial facility or your home drainage center, Dura Slope's modular design adapts easily to any layout.

Choosing the Right Dura Slope Components


An effective Dura Slope Channel Drain system includes several essential elements: sloped channel sections, end caps, catch basins, and transition fittings. Choosing the right configuration depends on flow demands, layout, and structural load requirements. Each site has different drainage challenges, so matching component specs to these variables ensures long-term performance and code compliance.


Maxx Drains carries grate options in cast iron, galvanized steel, and plastic. Selecting the correct drain grate provides optimal performance based on site traffic levels, aesthetic needs, and environmental exposure. Many options include tamper-resistant locking tabs to secure components in public or high-use areas, such as schools, parks, or commercial centers.


Our systems also support modular layouts using neutral channel drains and neutral sections, giving you the flexibility to adapt the drain layout to your site plan. These systems connect seamlessly with your connected drain pipe network for efficient water transport and proper release downstream. Because of their modularity, installers can scale up or redirect the flow path without needing custom fabrication.


Consult with NDS project specialists to explore the best trench drain systems for your project. Whether you need to manage heavy traffic or blend seamlessly into landscape design, we help you choose the right Dura Slope channel and accessories. For applications requiring a low-profile look, slot drain covers are also compatible with Dura Slope systems.


Installation Tips for Dura Slope Trench Drains


Proper installation ensures that your trench drain performs reliably. Begin by excavating the trench to the proper depth and slope. The factory-sloped channels simplify this step, with clearly marked indicators to align sections correctly. This reduces the risk of uneven flow or pooling, especially on long installations across sloped surfaces.


Use rebar clips to anchor channels securely before pouring concrete. Seal all joints with approved adhesives or sealants to prevent leaks. After the concrete has cured, install the grate to complete the setup. Installing grates last also protects them from shifting or damage during the concrete pour.


Choose your grate based on traffic load—from pedestrian areas to heavy vehicular zones—and consider optional concrete staining for visual appeal in exposed areas. Maintaining the system involves removing debris from the drain and inspecting the catch basin for blockages. Simple seasonal checks can prevent buildup that restricts flow and leads to surface flooding.


All NDS channel components are marked with directional arrows to ensure correct flow alignment during setup. Following these basic steps will ensure long-lasting performance while also reducing the likelihood of costly repairs or replacements over time.
